DNS Propagation Checker

Check real-time DNS records across global resolvers. Verify propagation status for A, MX, NS, and more.

What is DNS Propagation?

DNS propagation is the time it takes for DNS changes to be updated across the entire internet. When you update your nameservers or DNS records, the change doesn't happen instantly. It can take anywhere from a few minutes to 48 hours for the new information to spread to all DNS servers worldwide.

⚠️ Important: Just because you see the correct record here doesn't mean every user in the world sees it yet. Local ISP caches can persist longer than global resolvers.

Understanding TTL (Time to Live)

TTL stands for "Time To Live." It is a setting on DNS records that tells servers how long to cache (store) the information before checking for updates again.

  • Short TTL (300s / 5 min): Good for planned changes. Updates propagate quickly but increase server load.
  • Long TTL (86400s / 24 hrs): Standard for stable records. Reduces load but makes updates slower.

If you plan to move your website, lower your TTL a day in advance to ensure the switch happens smoothly!
