DNS Propagation
DNS Propagation Checker
Check whether your DNS change has reached 12 global resolvers. Use this after updating any DNS record to confirm the new value is live worldwide.
Enter a domain and select a record type to check propagation
About this tool
- How long does DNS propagation take?
- Most DNS changes propagate globally within minutes to a few hours. The actual time depends on the TTL of the old record — resolvers cache records until the TTL expires. Use a short TTL (e.g. 300s) before making changes to speed up propagation.
- Why do different resolvers show different values?
- Each resolver caches records independently based on their TTL. After a change, resolvers that have cached the old value will continue returning it until the cache expires. This is normal and expected during propagation.
- What is DNS TTL?
- Time to Live. A value in seconds that tells resolvers how long to cache a DNS record before re-querying the authoritative nameserver. Shorter TTLs mean faster propagation of changes but more DNS queries.
- Why does the checker show 'No record found'?
- Either the record genuinely doesn't exist yet, or the change hasn't started propagating. Check your DNS provider to confirm the record was saved correctly. If recently added, wait a few minutes and try again.
