Free DNS Tools by Connected Geek
DNS Propagation Checker
See whether a DNS change has reached the rest of the world, and exactly how long outdated caches have left.
Try an example:
1
We ask the source
Your domain's own nameservers are queried directly. Their answer is the correct, current record.
2
We check the world
Real devices on networks across six continents, plus major public resolvers, report what they currently have cached.
3
We show what is left
Every outdated cache shows its remaining time, so you know exactly when a change will be visible everywhere.
