Free DNS Propagation Checker
Query 6 global DNS resolvers (Cloudflare, Google, Quad9, OpenDNS, NextDNS, AdGuard) and see at a glance whether your DNS change has rolled out everywhere.
How it works
Pick a hostname and record type
A, AAAA, CNAME, MX, TXT, or NS — anything that propagates.
We hit all resolvers in parallel
DoH (DNS-over-HTTPS) queries to 6 public resolvers; results return within seconds.
Read consistency at a glance
Same answers everywhere → propagated. Different answers → still rolling out. Easy.
Frequently asked questions
How long does DNS propagation take?+
Bounded by your record's TTL. Cached resolvers won't refetch until the TTL expires. If you lowered the TTL ahead of time, propagation completes within that window (often minutes); if not, expect up to the original TTL (sometimes 24h+).
Why does one resolver still show the old value?+
That resolver has the old record cached. It'll re-fetch when its cache entry hits its TTL. Nothing you can do to force it — though Cloudflare and Google both have public 'flush cache' pages.
Are these resolvers regionally distributed?+
All six use global anycast networks — your query lands on the closest PoP. So the variance you see in answers reflects each operator's internal caching rather than literal geographic distance.
Is DoH the same as 'real' DNS?+
Same data, different transport. DoH packages standard DNS queries over HTTPS — what the resolver sees and returns is identical to UDP/TCP DNS.
