Let’s explore one DNS record with multiple purposes – the DNS TXT record. It is used for various verification methods, and it is essential to the right mail server functionality.
What is a DNS TXT record?
The DNS TXT record is one DNS record type with multiple purposes like authentication, verification, mail policies, and more. The DNS TXT record is showing domain information to external sources.
The TXT record has a text field that can be filled with readable instructions for people or with instructions for computers like cryptographic keys and email instructions.
You can add multiple TXT records for the same DNS zone. They can have different purposes, and sometimes they can work together, like in the case of DMARC.
