Domain Name System (DNS)

Text [TXT] Record

A Text Record provides the ability to associate some text with a domain or a subdomain. This text is meant to strictly provide information and has no functionality as such. A TXT Record can store upto 255 characters of free form text. This record is generally used to convey information about the zone. Multiple TXT records are permitted but their order is not necessarily retained.

For example, you may add a TXT Record for yourname.com with the value as "This is my mail server". Here if anybody was checking ALL or TXT records of yourname.com, they would notice the above text appearing in the TXT record.

TXT Record is also used to implement the Sender Policy Framework (SPF) and DomainKeys specifications.
