DNS Propagation Checker

Free online DNS Propagation Checker. No sign-up needed, and it runs in your browser.

Processed on your device

Check whether a DNS change has reached the big public DNS resolvers — Cloudflare, Google, Quad9, OpenDNS and 8 more.

Every resolver keeps its own copy (cache) of your records until the TTL runs out, so right after a change some show the old answer. The flags show where each DNS company is based; their servers answer from many countries.
