DNS Propagation Checker
DNS (Domain Name System) is the internet's address book, and a change only appears once each resolver's cached copy expires. Query three independent public resolvers at once and compare their answers — differing results usually mean the old TTL has not run out yet.
What is DNS propagation?
There is no single global DNS database to update. Each resolver caches answers for the record's TTL, so after a change some visitors keep getting the old address until that cache expires. Agreement across independent resolvers is the practical sign that a change is live everywhere.
