DNS Propagation Checker
Check DNS propagation across global nameservers
DNS propagation is the process of DNS changes spreading across the global DNS infrastructure. This can take anywhere from minutes to 48 hours.

What is DNS Propagation?
DNS propagation is the process by which DNS changes spread across the global DNS infrastructure. When you update DNS records, it takes time for these changes to be reflected on all DNS servers worldwide.
How DNS Propagation Works:
- You make changes to your DNS records at your DNS provider
- Your authoritative nameservers are updated with the new records
- DNS resolvers around the world gradually cache the new records
- Old cached records expire based on their TTL (Time To Live) values
- New records are fetched and cached by DNS resolvers
- Eventually, all DNS servers worldwide have the updated records
Propagation Timeline:
Immediate0-5 minutes
Authoritative nameservers updated
Partial5 minutes - 4 hours
Major DNS resolvers updated
Complete4-48 hours
Global propagation complete
Why Propagation Takes Time:
- DNS caching improves performance but delays updates
- TTL values control how long records are cached
- Thousands of DNS servers worldwide need to be updated
- Some ISPs and organizations use longer cache times
- Network latency affects update speed
