The TXT is a type of DNS record that stores miscellaneous information in a human- and machine-readable format.
It allows domain administrators to add custom text to their domain's DNS settings, providing various types of information for sources outside their domain.
The data stored in a TXT record can be used by other systems to verify domain ownership, authenticate email senders, and perform other essential functions.
One of the primary uses of the TXT record is for email authentication. It is commonly employed for implementing SPF, DKIM, and DMARC protocols.
