DNS Propagation Checker

Compare current DNS answers from independent public recursive resolvers without pretending to provide worldwide monitoring.

What this checker tests

  • Google Public DNS response
  • Cloudflare resolver response
  • Answer agreement
  • A, AAAA, MX, TXT, CNAME, or NS records

How to understand the result

Recursive resolvers cache records according to TTL.

Different answers can be normal shortly after a change.

This tool compares independent public resolvers; it is not a network of geographic probes.

Common problems

  • Resolvers disagree after expected TTL expiry
  • No record returned
  • An upstream resolver timeout
  • Authoritative data differs from the intended configuration
