There are various types of DNS Resource Records that are used for different management purposes. The most common ones are:
- 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 - this is similar to A record, but it lets you point to a domain with an IPv6 address.
- CNAME - this record is used to alias one domain name to another. For example, you can enter a domain name that you want to relate to another one, then fill the domain string of the related domain. When someone visits any of your entered websites, they will see the same content on both of your domains.
- MX - MX 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 - this record stands for Sender Policy Framework and allows the owner of the domain to publish a list of IP addresses to send emails on his behalf.
- SRV - this record defines the location, hostname and port number of the domain name you enter. SRV record points one domain name to another, while using a port of specific destination.
- TXT - this is a text record that maps a DNS name to a description that you enter.
