DNS Checker
Look up DNS records from resolvers around the world and the authoritative servers, and see whether a change has propagated.
- via Check-Host.net
All the record types
A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, SRV, PTR, and modern types like HTTPS/SVCB and DNSSEC records — decoded and shown clearly.
Propagation view
We query many public resolvers and the zone’s own authoritative servers, then group the answers so you can instantly see whether a DNS change has reached everywhere or is still propagating.
Authoritative and public resolvers
Records are queried from many public resolvers around the world and directly from the domain’s authoritative name servers, so you can compare what different networks see.
Frequently asked questions
Has my DNS change propagated?
The propagation view groups answers from resolvers worldwide. If they all agree with the authoritative server, propagation is complete.
How long does DNS propagation take?
It depends on the TTL of the old record: resolvers keep answers until the TTL runs out, so a change can take from minutes to 48 hours. Lowering the TTL before a planned change shortens the wait.
What does NXDOMAIN mean?
NXDOMAIN means the domain name does not exist. Check for typos, an expired domain or a missing delegation at the registrar.
Which record types can I look up?
A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, SRV, PTR, HTTPS and the DNSSEC records DNSKEY and DS.
