What are the different types of DNS records?

There are several types of DNS records. Each has specific roles and functions. Here is a short list of the main ones to help you distinguish them and understand their respective uses.

The most common DNS record types

A: This record is used to match a DNS name to an ipv4 IP address.
Example: IN A

AAAA: This DNS record is used to match a DNS name to an ipv6 IP address.
Example: IN AAAA 2b04:ehf:1:f:3p0:c4ff:fia5:4da0

*CNAME: This type of record is used to match two DNS names.
Example: sql.mondomaine.ext. IN CNAME mysql1.unautredomaine.ext.

MX: An MX record allows you to configure for a given DNS area (associated with mail servers) in the form of a DNS name.
Example: IN MX 10

The DNS name used in an MX record must be of type A. It is not possible to use an IP or a CNAME record.
The figure represents the priority level. This is the order in which mail servers must be contacted if there is more than one.

TXT: This record stores a string of up to 1024 characters. As the name indicates, it is used to add text elements.

URL Redirect: This record allows you to redirect your domain (or subdomain) to another web address. The redirect is not displayed in the URL address bar.

URL Frame: Like the Redirect URL, this record does the redirect to the specified website. However, it differs by displaying the redirected domain name in the URL bar
