TXT Record Lookup
Find text records for verification and configuration
This page provides original, human-reviewed information about TXT record lookups, covering SPF, verification tokens, and arbitrary text payloads, plus handling of multi-string records over 255 characters.
TXT records allow domain administrators to insert arbitrary text into DNS records. They're commonly used for domain verification, email security policies, and various service configurations.
Common TXT Record Uses:
- SPF Records:Email authentication and anti-spoofing
- DMARC Policies:Email security and reporting policies
- Domain Verification:Prove ownership for services like Google, Microsoft
- DKIM Keys:Email signing public keys
- Site Verification:Search engine and service verification
- Security Policies:CAA records for certificate authority authorization
