What Do Different DNS Records Mean?

There are many types of DNS Resource Records that are used for different management purposes. The most common ones include:

  • A – the most common record for setting up domain and subdomain access. This is a host record that directs a hostname to a numerical IP address.
  • AAAA – similar to A record, but AAAA lets you point to a domain with an IPv6 address.
  • CNAME – this record is used to map an alias domain name to a standard domain name. This means that you can enter a domain name that you wish to relate to another one, then fill the domain string of the related domain. When someone visits any of the related websites, they will see the same content on both of your domains.
  • MX – this record explains how to send an email to your domain. In other words, it directs the domain’s mail flow to the server that was configured to process mail for your chosen domain.
  • LOC – this type of record determines the geographical location of your entered domain.
  • SPF – the Sender Policy Framework record allows the owner of the domain to publish a list of IP addresses to send emails on their behalf.
  • SRV – this record defines the location, hostname and port number of the domain name you enter. The SRV record points one domain name to another while using a port of a specific destination.
  • TXT – this is a text record that maps a DNS name to a description that you enter.
