DNS records explained

DNS stands for Domain Name System. The main function of DNS is to translate domain names into IP Addresses.

The DNS records for each domain are stored in its active DNS zone. The active DNS zone is where the name servers of the domain are pointed.

There are a lot of DNS record types  The most commonly used DNS record types are (A, MX, CNAME, TXT, AAAA, SRV).

In this post, we are going to talk for each one of them and its porpouse.

Let’s talk DNS


  • A – specifies IP addresses corresponding to your domain and its subdomains.

    Example A record:

MX Record


  • MX – specifies where the emails for your domain should be delivered.



  • CNAME – specifies redirects from your domain’s subdomains to other domains/subdomains.



  • TXT – used to store text-based information related to your domain. Most commonly used for storing SPF data.



  • AAAA – it maps a domain name to the IP address (IPv6) of the computer hosting the domain.



  • SRV – stands for Service Record and it specifies on only an IP but also a port.
