TXT-records are used to hold descriptive text.

 

They are often used to hold general information about a domain name such as who is hosting it, contact person, phone numbers, etc.

 

One common use of TXT-records is for SPF (see http://www.openspf.org).
This is however gradually being replaced by the new SPF-record type.

 

To create a new TXT-record, right-click a zone in the left list in the DNS Records window, and select "Other new record" from the pop-up menu.

 

This record type is defined in RFC1035.
