What is DNS Propagation?

DNS changes typically propagate globally within 1–48 hours, depending on the TTL (Time to Live) set on your DNS records.

Different resolvers around the world may have cached your old DNS records. This tool shows you exactly which locations have your new records.

Before making DNS changes, lower your TTL to 300 seconds (5 min). This speeds up propagation. Restore it to 3600+ after changes are confirmed.
