Tools / DNS propagation

DNS propagation checker

Compare current A, AAAA, MX, and NS answers from Cloudflare, Google, and Quad9 resolvers.

Interpreting differences

A difference can reflect caching, TTLs, geographic anycast, resolver policy, or a recent DNS change. Results are a point-in-time comparison, not proof that a record has or has not propagated worldwide.

For the full record set and DNSSEC details, use the DNS records lookup.
