Check if your DNS changes have propagated worldwide. Test from 20+ global locations across Asia, Europe, Americas and more.
When you change DNS records, it can take 24-72 hours for the change to spread to all DNS servers worldwide. This tool checks 20+ resolvers around the globe to see which ones have your latest record.
When you update a DNS record — like pointing your domain to a new server or changing your MX records — the change doesn't take effect instantly everywhere. DNS servers around the world cache records for a period defined by the TTL (Time to Live) value. Until that cache expires, some users may still see your old records.
Our tool queries 20+ real DNS resolvers across the globe simultaneously and shows you exactly which ones have picked up your new record and which ones are still showing the old value.
Typically 1 to 48 hours, but sometimes up to 72 hours for full global propagation. Setting a lower TTL before making changes (e.g. 300 seconds) can speed this up significantly.
Why do some locations show different results? Each DNS resolver caches records independently. Until the TTL expires, they serve the old cached record.
What does 100% propagation mean? All 20 resolvers we test are returning the same (or a) record for your domain. It doesn't guarantee every ISP worldwide has updated, but it's a very strong indicator.
