Exam CV0-003 topic 1 question 257 discussion

A TXT (Text) record in DNS is commonly used for domain verification purposes. Many third parties, such as SSL providers, cloud services, and email security services, require the domain owner to add a TXT record containing a specific verification code or secret. Why TXT? TXT records can store arbitrary text data, such as ownership verification tokens, SPF (Sender Policy Framework) settings, DKIM (DomainKeys Identified Mail) keys, and security policies. Many services (Google, AWS, Microsoft, etc.) use TXT records to confirm domain ownership before allowing access to services.

This is a common method used for domain ownership verification or various other purposes, such as email authentication (SPF and DKIM) or site verification for search engines like Google. The TXT record can contain arbitrary text information, including the secret provided by the third party.
