Domain name system (DNS) records look like small components, but their role is really important. Those small pieces of data accomplish specific purposes. They are key for the Internet’s performance and its permanent interaction with domains.
Here you have what is important to know about the DNS TXT record.
What is the DNS TXT record?
TXT or text records are the ones that have text format data for external sources. This means sources outside domains like yours. Usually, on these records, you can find general domain information but also key data required for validation. Through TXT records, ownership of a domain can be verified, data for e-mailing can be validated, etc.
This type of record was created for human-readable notes for administrators. But since text has become a common language for machines too, it is readable and understandable for both. This advantage makes DNS TXT records a vital tool for administrators to give instructions to machines through entering text into the DNS.
