DNS lookup & propagation checker
Look up any DNS record across several public resolvers at once and see whether your change has propagated — or is still rolling out around the world.

When every resolver returns the same answer, your record has propagated. While it differs, some networks are still serving the old value from cache — give it up to the record's TTL and check again.
This domain is served through Cloudflare. Its proxied addresses are anycast and differ between resolvers by design, so varying results here are expected rather than a sign your DNS hasn't propagated.
What is DNS propagation?
When you change a DNS record, the new value doesn't reach the whole internet at once. Resolvers around the world cache the old answer until its TTL (time to live) expires, so for a while different networks can hand back different results. That window is DNS propagation.
This tool queries several independent public resolvers at the same time and compares their answers. If they all agree, your change is live everywhere this tool can see. If they don't, it's still rolling out — wait for the TTL and check again.
