TXT record

A TXT record (short for text record) is a type of resource record in the Domain Name System (DNS) used to provide the ability to associate some arbitrary and unformatted text with a host or other name, such as human readable information about a server, network, data center, and other accounting information.

Usage

A domain is not limited to having only one text record. Any fully qualified domain can potentially have several records. Each record can have one or more character strings.

Common uses include defining to verify domain ownership or in setting up Sender Policy Framework, DomainKeys, DomainKeys Identified Mail records which are used to validate legitimate email sources from a domain, and Zero-configuration networking DNS-based service discovery.
