How to change DNS server and why to do it?

Have you bought a domain and want to change your DNS - the Domain Name Servers? Are you at the beginning of your journey, wondering what Domain Name Servers and DNS records actually are and how to set them?

This article will cover how to change DNS servers and connect a domain to a server. DNS configuration will be easily achieved once you have these instructions at hand.

DNS, or Domain Name Servers

DNS is the abbreviation for Domain Name Servers. In a nutshell, Domain Name Servers are a set of computers that are responsible for publishing websites, forums, or applications on the web.

The main function of the servers is to translate complex IP addresses into easy-to-remember domain names. When the name of a website is entered into a search engine, the server will easily find the IP address assigned to the website. Such servers are called recursive servers.

With such servers, you can publish your company website or blog. If you have registered your domain with Let's Domains, we will show you how to assign Domain Name Servers step by step. This will make every change done easily for you.

Servers that remember and store your domain configuration are called authoritative servers (e.g., DNS authoritative servers usually consist of two or three DNS servers:



Most often each server has a different IP address (different IP address) due to technical aspects. The different IP address is the standard when it comes to DNS configuration. Authoritative servers are also responsible for storing records corresponding to services such as the website or mail.

Hosting is a service provided on servers. It consists of separating and providing a part of the server with certain parameters. You will find many hosting providers on the Internet. In most cases, the hosting provider offers several hosting packages which differ in terms of space or individual parameters.

Management systems (cPanel, DirectAdmin, Plesk)

Many hosting providers will offer various management systems. Among the most popular you can find:

  • cPanel - cPanel is an extremely intuitive and easy-to-use hosting administration panel. cPanel is available in 36 languages. cPanel is an easy way to manage your files, mail, or DNS zone.

How to add secondary DNS server?

A secondary DNS server is a server that, in the event of a failure of the primary DNS, retrieves the configuration and, despite the failure of one of the servers, the content is still displayed without service disruption. It is important that when you add DNS servers, you enter all that your provider indicates to you. If it is three server names, enter three; if it is two servers, enter two. It is important that you add a secondary DNS server. Entering a set of DNS servers allows your site to operate without service disruption. Need help setting up DNS servers?

How to connect domain to a server?

Connecting a domain to a server is possible in two ways:

  • By changing the DNS servers. We have described the individual steps of how to set the DNS configuration above.


  • By updating DNS records. We have included information on how to add DNS records on the servers below.

DNS records

Assigning a domain to specific servers is the first step in its configuration. The next step is to set up the various services: mail, website or applications. In Let's Domains, you can set up the following records:

  • A record - address record - Points the domain to an IPv4 address.
  • AAAA record - address record - Directs the domain name to an IPv6 address.
  • CNAME record - canonical name record - Directs the domain name alias to another name. Cannot be set for a root domain.
  • MX record - mail exchange record - Responsible for redirecting the domain name to the mail server name. It has a defined numerical priority (in case of several identical entries, they are processed according to the priority from its lowest values, this is important e.g. in case of failure of one of the servers).
  • TXT record - Allows appending any text to a DNS record. TXT records are also often used to authenticate rights to a domain, e.g. by the Google Search Console service.
  • SRV record - service record - Contains additional information about the location of a particular service that the server provides. Allows you to authenticate mail.
  • CAA record - The CAA record in a domain's DNS indicates which issuers are authorized to issue an SSL certificate for the domain. If the record does not exist, then any issuer can issue an SSL certificate (after authorizing rights to the domain, of course). If a CAA record exists, then an issuer not listed in the record will not issue a certificate (despite confirming rights to the domain by any means).

Where to get information about the content of the records? Most often, record information is provided by the operators responsible for the service. If you need help with setting up the records, please contact our customer service. We will be happy to help you with the DNS configuration.

How to update DNS records?

Management and updating DNS records constitute an important part of domain services. To update DNS records, go to the administration panel: Enter your e-mail address and password.

login to manager

Go to Domains > Domains list. Click the domain for which you want to update DNS records. Find the DNS hosting option and click Manage.
