Query 8 public DNS resolvers simultaneously via DNS-over-HTTPS to check if your DNS records have propagated worldwide. Shows per-resolver answers, TTL, and latency.

Enter a domain and select a record type, then click Check.

Queries 8 public resolvers simultaneously, through our server.

The domain you enter is sent to our server, which asks 8 public resolvers (Cloudflare, Google, Quad9, AdGuard, NextDNS, OpenDNS, Comodo, CleanBrowsing) and compares their answers. Results reflect each resolver's current cache — propagation can take up to 48h.

Frequently asked questions

Is my data uploaded to a server?

Partially — see the note above. The domain you check is sent to 8 public DNS-over-HTTPS resolvers to compare their answers; that's the whole point of a propagation check.

How does the propagation check work?

It asks 8 public DNS resolvers (such as Cloudflare, Google, Quad9 and OpenDNS) at once, relayed through the site's backend, and shows each resolver's answer, TTL and latency.

How long does DNS propagation take?

It depends on the record's TTL and resolver caches. Comparing the answers per resolver shows which still return the old value.

Which record types can I check?

A, AAAA, CNAME, MX, TXT, NS, SOA, PTR and SRV records, for example after a mail server migration.
