DNS server definition. What is DNS, how it works and how to specify or change DNS servers for a domain

"How to find out the provider's DNS server," - such a question can sometimes arise both for experienced users and for people who solve their problem with accessing the network. It may arise when it is necessary to configure Internet access through the internal network using a specific DNS server address, and not an automatically determined address. This is usually needed if there are always some difficulties with the dynamic address pool. Such a connection is more stable and allows you to set up DSL access without line breaks.

by the most simple option How to find out the DNS provider is a call to the support service. Operators usually provide two addresses that you can enter in the network settings you configure. If for some reason this cannot be done, use our tips below.

Admin tip! If there is a problem accessing the network. It is possible that the dns address determination service is not working correctly, as a result you will have a physical connection to the network, but without access to the Internet through a browser. This can be fixed by a normal reboot of the computer, advanced users can restart the service and restore the network over the http protocol.

How DNS works

The principle of operation of DNS (Domain Name Services) is well demonstrated in the illustration. The user sends the usual textual name of the site and in response receives an IP address that already provides access to a specific resource. The DNS is a global network of server routers that provide daisy chain connectivity to the server system and access.

Admin tip! Ordinary users do not need to configure network settings and clarify the DNS provider and other sites. But for general development, you need to know that each text name is associated with a specific IP address, for example, 78.1.231.78.

DNS spoofing - a classic hacker attack

Experienced users will be interested to get acquainted with the scheme of servers that provide access to the Internet. A DNS server that routes user traffic is also available on the side of your provider.

Admin tip! Please note that when the DNS server is spoofed, it is possible to connect to a "fake" site. This interface is used to steal passwords and credit card information. Usually this issue is resolved by installing anti-virus software, which includes protection against such "traffic listening".

DNS provider

As we said, to set up a network connection, the DNS address of the provider is required. Usually there are several of them, especially for large telecommunications systems to which many users connect. Usually in the support service you can find out the primary and secondary DNS, these servers duplicate each other when there is a rather large load when users connect.

Determining the DNS provider from your network

The easiest way to do this is when there is a network and Internet access, or the same can be done from a subscriber who is also served in your provider's network. For these purposes, follow the instructions:

  • launch the command line by clicking on the "Start" menu, then "Run" and typing CMD (lower case) in the line;
  • in the command line window that opens, type ipconfig / all;
  • in the report you will receive a list of DNS addresses;
  • the received addresses can be physically registered in the network settings, in which case access to the network will work stably even if the automatic discovery of DNS servers fails.

This method helps to make network access more stable, in fact, you assign a permanent DNS server with a backup address. Both servers will route your requests on the Internet.

Screenshots

Examples are shown on screenshots. In the first case, the standard server addresses are indicated. In the second case, reserve and additional. In this option, users have access to three redundant servers.

Alternative ways to find provider DNS addresses

If you do not have access to the network, the support service does not give direct DNS addresses and you cannot get them in another way, try searching through an Internet search. This can be done using search engine and keywords "DNS addresses (name of your provider)". In some cases, this information may be posted on the official website of the telecommunications company or in forums by users.

What is DNS, how it works and how to specify or change DNS servers for a domain - 3.5 out of 5 based on 2 votes

DNS - (Domain Names System) Domain Name System - is a network service, on the servers of which domain names are compared with the digital values ​​of their IP addresses.

Let's take a closer look at what DNS is, how it works and how it works.

The Internet is an IP network and each computer in this network has a specific personal number, which is called an IP address. But since it is not convenient to use digital addressing, it was decided to use the alphabetic spelling of addresses. Therefore, when you go to any sites on the Internet, you do not enter numbers, but letters. But the problem is that computers can only perceive digital information, that is, a sequence of ones and zeros, and absolutely cannot understand alphabetic information.

That is why a special service was created on the Internet that translates letters of addresses into numbers and this service is called DNS (Domain Name System).

The DNS service is a huge database that contains information about the correspondence of a specific domain name to a specific IP address. Visually, it can be depicted as follows:

There are a huge number of domain names on the Internet and more and more every day, so you can imagine how huge the database of this service is. It is not reasonable and practically impossible to store such a large amount of information on one server.

But since the Internet network consists of subnets, it was decided to split this database and place its certain size in each of the subnets. Where there are correspondences of IP addresses to domain names only for computers included in this subnet.

What is NS server

The server that contains all the information about the correspondence of domain names in a particular subnet is called the NS server, stands for Name Server or name server. Consider an example of converting a domain name to an IP address based on a simplified network.

As you can see, in this network there is a computer with the alfa domain with an IP address of 192.55.11.25 and a computer with beta domains with an IP address of 192.55.11.26, and the DNS server itself, which also has the corresponding IP address. Now suppose the beta computer needs to contact the alfa computer, but it doesn't know its IP address, only its domain name. However, it knows the IP address of the DNS server to which it accesses to find out the IP address of the alfa server. The NS server searches its database and, finding the IP address that matches the alfa domain name, passes it on to the beta computer. The beta computer, having received an IP address, uses it to contact the beta computer.

As you know, all domain names have their own hierarchical structure and are divided into .ru domain zones. com and others. See the material for more details. So, each domain zone has its own NS server containing information about the IP addresses of those domains that are included in a specific domain zone. Thus, this huge database is divided into smaller ones.

DNS setting

How can I change and specify DNS servers for a domain.

In order for it to load when you enter the address of your site in the address bar of your browser, you need to associate the domain name of the site with the hosting. To do this, we must tell the DNS service which NS server to contact, so that it, in turn, looks in its database and tells which server (hosting) to contact the browser.

The DNS server entry looks like this:

ns1.yourhosting.ru
ns2.yourhosting.ru

You can find these addresses:

  • in a letter that the hosting provider sends you immediately after ordering hosting;
  • in the hosting control panel, for example, in the domains section;
  • by contacting hosting support.

Now about where they need to be specified. These DNS server addresses must be specified to the domain that you are going to use as the address of your site. Therefore, go to the website of the domain name registrar where you registered your domain. In the domain management, find the item DNS servers or Manage DNS servers / Delegation, the name may differ depending on the registrar. For example, at the domain name registrar that I use to register my domains, you need to go to the "My domains" section >> mark the desired domain and select "Change DNS servers" from the drop-down list.

After entering this section, a form will open in the fields of which you need to enter the appropriate DNS servers. To do this, in my case, you need to uncheck the box "Use registrar names" and then specify ns1.yourhosting.ru in the DNS1 field, and ns2.yourhosting.ru in the DNS2 field. IP addresses can be omitted, so some hosting providers do not issue them. After filling in the fields, click the "Edit" button.

After that, you need to wait a while until the DNS servers are matched. This can take anywhere from a few hours to a whole day. Therefore, as soon as you specify them, your site will not load.

How to specify your DNS servers for a domain

Sometimes you need to specify your own DNS servers, i.e. DNS servers that are located in the same domain. Almost everyone has their own DNS server service. In this case, for example, for this site, ns1..site is specified as the DNS server.

In doing so, the following points must be taken into account:

1. If you specify your DNS servers for a domain located in the RU, SU, RF zones, then you must specify its IP address for each DNS server. In this case, each specified IP address must differ by at least one digit; it is not allowed to indicate the same IP.

2. If the DNS servers that you specify for your domain name are in another domain, for example, if you specify DNS servers like 1ns.vash-sait.ru or 2ns.vash-sait.ru for the site domain, then you do not need to specify IP addresses .

3. If you specify your DNS servers for an international domain, then these DNS servers must be registered in advance in the international NSI Registry database. It is not possible to specify them without registration in this database. When registering with the NSI Registry, you will need to enter IP addresses for each DNS server. Therefore, when specifying DNS servers for a domain, there is no need to specify IP addresses.

Attaching an IP address to a domain

To attach an IP address to a domain, you need to go to the DNS records settings. How to do this will depend on the hosting control panel. For example, in ISPmanager you need to go to the "Domain names" section, then double-click on the required domain name and specify or edit the following three entries (to create an entry, click on the "Create" icon, to change, click on the required entry):

For the first entry, enter www in the "Name" field, select A (Internet v4 address) in the "Type" drop-down list, and enter the desired IP address in the "Address" field.

For the second entry, enter @ (dog) in the "Name" field, select A (Internet v4 address) in the "Type" drop-down list, and enter the required IP address in the "Address" field.

For the third entry, enter * (asterisk) in the "Name" field, select A (Internet v4 address) in the "Type" drop-down list, and enter the required IP address in the "Address" field.

Video: How DNS works

The material was prepared by the project:

Many owners of home PCs, laptops and tablets use the Internet without understanding the principles of its functioning at all. You can get a much more stable connection than the provider usually gives us by taking the time to study this issue. One option to improve your web browsing experience is to replace the default DNS address with an alternate one.

What is DNS and why is it needed

To begin with, let's figure out: what is the meaning of the letter combination DNS. The full name is Domain Name System, and translated into Russian means "domain name service". Each site on the Internet has its own domain name, we see it every day in the address bar of the browser. For example, for the well-known social network Facebook it will look like this https://www.facebook.com. In addition, each site has its own IP address in the form of a numeric value, like this: 31.13.65.36.

DNS server translates the site's domain name into an IP address

The function of DNS is to store data about the addresses and domain names of sites. When an alphabetic request for a site name is received, the DNS server returns the numerical value of the resource address.

How to find out which DNS is provided by the ISP

If you periodically have difficulty accessing the Internet, it is better to use the setting of a specific DNS address, and not automatic tuning. Such a connection works more stable. To do this, you need to find out the address of your provider. The easiest way is to call the operator of the organization that supplies you with the Internet service. If this is not possible, find out the DNS address using Windows tools. To do this, you need to call the command line.

You must do the following:

  1. Open the "Start" menu, then "All Programs", on the "Accessories" tab, click "command prompt".

    Enter the "Start Menu" select "Command Prompt"

  2. Alternative way: simultaneously press the combination of the Win and R keys - in the tab that appears, type the command "cmd" and click "OK"

    On the Run tab, type "cmd" and click "OK"

  3. In the window that appears, type the command "nslookup" and press "Enter".

    Type "nslookup" in Command Prompt and press "Enter"

  4. This way you will get the provider's DNS address value.

    Your ISP's IP address will appear in the Command Prompt window.

Alternative DNS servers on the Internet, overview, pros and cons

Each ISP has its own DNS service, but sometimes it makes sense to connect to an alternative server. The reasons may be different:

  • the provider is not able to ensure the stable operation of the DNS;
  • the user seeks to increase the level of protection of his computer;
  • PC owner wants to increase network speed;
  • the desire to get rid of restrictions on access to information based on territorial position.

Consider best options and try to choose the most suitable one.

Google Public DNS

The service launched in December 2009 as an experimental service. It is currently the largest public DNS service in the world, averaging over 70 billion requests per day. It uses the CDN (Content Distribution Network) method of information transfer. Google Public DNS servers support the Internet protocol IPv 6.

    The Network icon indicates the presence of an Internet connection

  2. In the "Current Connections" tab that appears, select "Network and Sharing Center" and click the left mouse button.

    Left click on "Network and Sharing Center"

  3. In the new window, select "Local Area Connection".

    On the "View Basic Network Status" tab, left-click on "Local Area Connection"

  4. A new tab will appear, click Properties.

    On the tab that appears, click "Properties"

  5. Select "Internet Protocol Version 4 (TCP/IP 4)", click the "Properties" button again.

    Select "Internet Protocol Version 4 (TCP/IP 4)" and click "Properties"

  6. In the new tab, in the paragraph "Use the following DNS server addresses", fill in: "Preferred DNS server" and "Alternative DNS server".

    Fill in the "Preferred DNS server" and "Alternative DNS server" items, click "OK"

  7. Check "Verify settings on exit".
  8. Click the "OK" button and restart your computer.

Common DNS Errors and How to Fix Them

There are a few common DNS errors that users encounter from time to time:

  1. The DNS server is not responding, the DNS address of the server cannot be found.
  2. Windows cannot contact the device or resource.
  3. No access to DNS server.

If an error occurs, first of all, you need to check if the Internet cable has fallen out of the computer. If everything is fine, try connecting it directly, bypassing the router. If everything works without a router, try rebooting it. There are many varieties of these devices, but in general terms, the settings for all are almost the same. How to do this, consider the example of one of the models of the well-known brand TP-Link:

  1. Enter 192.168.0.1 into the address bar of your browser and click search.

    Enter the IP address of the router in the address bar of the browser

  2. In the window that appears, enter your username and password (the default is "admin", if the password has been changed, you must remember it).

    Enter your username and password correctly

  3. Click the Login button.
  4. In the router control panel that appears, select "System Tools".

    In the menu that opens, select "System Tools"

  5. The following window will open, in it click the "Reboot" item.

    In the "System Tools" section, click "Restart"

  6. In the next tab, the message “Press this button to reboot the device” will appear, press the button, confirm the reboot, wait.

After rebooting the router, the error should disappear. Elementary device failures happen quite often, do not rush to panic, any problem can be solved on your own.

Quite often the cause various errors DNS is a problem with your ISP's servers. If you have already taken the steps listed above, but the error message does not disappear, call your ISP, perhaps the reason lies in the incorrect operation of its DNS server.

If the provider's equipment is working, the router is working, the network is available, and the browser continues to give an error, such actions will help.

Site DNS (Domain Names System) is a system of distributed storage of keys and values ​​for them, linking information about the actual site with the domain name of the site.

How DNS Works

In this way, the Internet solved the problem of connecting domain names with the real Internet routing system - IPv4 and IPv6 addresses. The creators simply added a site directory feature and called it DNS.

Interesting fact

When the Internet was distributed to only a few computers, and the number of sites could be counted manually, the well-known hosts file was used to link the domain and the IP of the computer. It manually registered the addresses of web pages in pairs with the addresses of the servers serving the given domain. Instead of 128.0.0.2, it was possible to enter mysit in the / address bar of the browser e .com and get to the right resource. But as the network grew to immense proportions, it became necessary to create a centralized and constantly updated array. Hosts has been replaced by a generic DNS.

Consider the entire chain of requesting information about the site:

  • You entered the site name in the address bar of the browser, for example yandex.ru.
  • The browser recognized that it is clearly not an IP address in front of it, which means it needs to be obtained manually. The browser generates a request to the most convenient DNS server.
  • The DNS server, having received a request from the browser, requests information about the site along a long chain that reaches the root servers.
  • After receiving a response, DNS sends as a response the IP address of the server to which the specified domain name belongs.
  • The browser directs you directly by IP.

We talked about accessing root servers, which was a valid but rather rough rounding off of DNS routing information.

Root servers

Root servers are the 13 main DNS servers serving all existing sites in the world. All root servers are located in the USA.

There are 9 replicas of these storages in Russia, in the following cities: Moscow, St. Petersburg, Novosibirsk, Yekaterinburg and Rostov-on-Don

In real conditions, one request out of a thousand reaches the root node. If each browser request led to the passage of the entire chain of world servers, we would wait ten times longer for the download, and at peak times we would not receive a response from overloads at all. It turns out that the developers have made a powerful distributed data caching system.

If you once requested a domain, its data is stored in the server cache for a very long time. When you re-apply, DNS will not check the IP with other servers along the chain, but will simply give you the answer you received earlier.

How to find out the DNS of a site

In order to find out the DNS of a site, there are simple and free tools. All of them simply repeat the steps of the browser, displaying the response headers of the servers.

  • Go to the service page: https://2ip.ru/dig/.
  • Enter the domain name of the resource of interest in the "Domain" field.
  • Select the type "ANY" and click "Check".
  • All available information about the domain will be displayed on the screen.

How to set up and register the site's DNS

Let's consider step by step the process of setting parameters for a web resource.

  • After completing the domain registration procedure, you will be prompted to go to the delegation control panel. Go to the NS records management section.
  • For many, it is much easier to keep the site server and DNS records under one account, so domains are delegated to the hosting company's DNS servers. To perform this procedure, check with the hosting provider for the addresses of NS servers and enter them in the domain settings.
  • If you want to leave the default NS records, further configuration will have to be done in the control panel from the registrar. In case you changed NS to a hosting server, go to its control panel and add your domain to the list. Most often, the procedure receives a technical response after 48 hours, do not wait for the domain to instantly appear in the list.

After completing all the initial configuration settings, you can proceed to the direct configuration of the DNS records. Each control panel has its own characteristics, but the principle is the same - select the domain editing mode, change / add / delete the necessary parameter-value pairs, save, and after 24-72 hours the result is reflected on the site

Primary DNS Resource Records

ATTENTION: a dot is always placed after the hostname in DNS

yourdomain.com. A 127.0.0.1

The main setting of any domain. Association of a name with an IP address. Configured by you immediately after delegation.

CNAME sub.yourdomain.com. CNAME yourdomain.com

Subdomain creation tool. If you create a subdomain on the site, specify it in the CNAME directive, otherwise it will not be accessible.

MX mail.yandex.ru. MX0

Mail server entry for your site. Without specifying this directive, sending and receiving mail for the site will be impossible. If you use third-party services such as Yandex.Mail, carefully read the instructions for using this directive. The value of the second parameter is a priority number from 0 to 65535, where the priority decreases as the number increases. This means that attempts to access servers will start from the highest priority, but if it fails, they will go down the hierarchy further down.

TXT

Any text information. Used to connect services, check domain rights and add additional data to the DNS structure.

TXT record of the mailing policy

Contains information about servers that are authorized to send email on behalf of the domain.

Internet is a collection of local networks of computers located all over the world that communicate with each other according to uniform rules called protocols.

In order not to remember the numerical address of the computer, the DNS system was created. Domain Name System or DNS (Domain Names System), associates names like numeric addresses (185.12.92.137) that computers use to communicate with each other.

In order for your site with your domain name to work, you must specify the DNS servers on which it will be "recorded" on which server (hosting) your site is located. DNS servers look like:

ns1.yourhosting.ru
ns2.yourhosting.ru

There are three ways to set up DNS:

  1. registrar DNS. In this case, you will need to fully configure the DNS zone as in the third option.
  2. hosting provider's DNS. In this case, the hosting provider will do all the preliminary DNS setup, sufficient for the normal operation of your site.
  3. Third party DNS. You can specify DNS hosting in general on a third-party DNS server, such as Yandex-DNS.

How to specify (change) DNS servers for a domain?

To specify/change the DNS server for a domain, you need to:

  1. register with a domain name registrar;
  2. Find the desired domain and select there "DNS Server Management / Delegation"
  3. In the form that opens, specify the required DNS servers (IP can be omitted). or check the "Use registrar's DNS servers" checkbox.
  4. Click on the "Save" button.

Information about your changes will be available for a period of several minutes to 72 hours. Therefore, at first it is possible that the DNS servers will be old. This does not depend on the registrar or the hosting provider. You just have to wait.

Setting up DNS records.

To add/change records on the DNS server, you need to do the following:

An example of making records in DNS:

Suppose you have registered the mydomain.ru domain and the IP address of the web server where the site will be located - 195.128.128.26. In this case, you will need to create at least two "A" records for your domain (to link mydomain.ru and www.mydomain.ru to 195.128.128.26). To do this, in the form for adding "A" records, in the "Subdomain name" field, specify "@" for the first record and "www" for the second record, and in the "Data" field, specify 195.128.128.26 (for both records).

To forward all subdomains to an IP address, you need to specify * as the "Subdomain Name"

Example 2: You want mail.mydomain.ru to point to the same host as relay.highway.ru. To do this, enter "mail" in the "Subdomain name" field, select "Record type" CNAME, and enter "relay.highway.ru." in the "Data" field.

An example of DNS records for the mydomain.ru zone:

@ A 195.161.114.80 @ MX 10 relay.highway.ru. www A 195.161.114.80 ctrl CNAME ctrl.muse.highway.ru. ftp CNAME ftp.muse.highway.ru. mail CNAME relay.highway.ru. ssh CNAME ssh.muse.highway.ru.

Instructions for Changing DNS Servers

  1. If you specify DNS servers located in the same domain (i.e. "your" DNS) for the RU, SU, RF domain, for example, for the domain testsite.ru you specify DNS servers ns1.testsite.ru and ns2.testsite.ru, then necessarily you must specify for each DNS server its IP address.
  2. If you specify DNS servers in any domain that are located in another domain, for example, for a domain testsite.ru you specify DNS servers ns1.abrakadabra.ru and ns2.abrakadabra.ru, then specify IP addresses for each DNS server no need.
  3. IP addresses of DNS servers (if necessary, see above) for RU, SU, RF domains must differ by at least one digit! Same IP for all DNS is not allowed.
  4. For international domains (com, net, org, info, etc.), the DNS servers that you specify for the domain must be necessarily registered in the international database NSI Registry. If they are not registered there, then they cannot be specified. For international domains, IP addresses do not need to be specified at DNS servers. They are specified when registering DNS in the NSI Registry database.

How to attach a domain to an IP address?

In order to attach a domain to an IP address, you need to:

Now you need to wait until the changes take effect and your site will open from this IP address. This may take up to 72 hours.

How long does a DNS change take?

Changes to DNS are made instantly. But due to the fact that providers cache DNS, the process of changing DNS around the world can take from several minutes to 72 hours.
