DNS Propagation Checker

Just changed a DNS record? See whether it's gone live by comparing what three major resolvers return right now.

Queries three major public resolvers (Google, Cloudflare, dns.sb) at once. Matching records mean your change is consistent everywhere. Differing answers usually mean a change is still rolling out (minutes to 48 hours, depending on your TTL) — but big sites on a CDN or geo-balanced DNS legitimately return different IPs by location, which is normal, not a problem.
