Check DNS Propagation Globally
Multi-Resolver DNS Checker

Query your domain against Cloudflare, Google, and Quad9 resolvers to verify DNS changes have propagated worldwide.

Frequently Asked Questions

What is DNS propagation?

DNS propagation is the time it takes for DNS changes (like updating an A record or changing nameservers) to be reflected across all DNS servers worldwide. During propagation, different resolvers may return different results — some showing the old data, others the new.

How long does DNS propagation take?

Propagation typically takes anywhere from a few minutes to 48 hours, depending on the TTL (Time To Live) of the old records, caching behavior of resolvers, and the type of change. Lowering your TTL before making changes can speed up propagation.

Which DNS resolvers does this tool check?

This tool queries three major public DNS resolvers: Cloudflare (1.1.1.1), Google (8.8.8.8), and Quad9 (9.9.9.9). These resolvers are geographically distributed and widely used, giving a good representation of global propagation status.

What does 'Fully Propagated' mean?

When all queried DNS resolvers return the same set of records for your domain, the tool shows 'Fully Propagated'. If some resolvers return different results, it means propagation is still in progress.

Which record types can I check?

You can check A (IPv4 address), AAAA (IPv6 address), MX (mail exchange), NS (nameserver), TXT (text records like SPF/DKIM), and CNAME (canonical name alias) records.

Complete Guide: How to Use the DNS Propagation Checker

Check DNS propagation worldwide to see if your DNS changes have taken effect across different geographic regions. Our tool queries multiple DNS servers around the world and shows you which ones have updated records and which still show cached (old) values. Essential after making any DNS changes.

Step-by-Step Instructions

1
Enter your domain
Type the domain whose DNS propagation you want to check (e.g., example.com).
2
Select the record type
Choose the DNS record type you changed: A, AAAA, MX, CNAME, TXT, or NS.
3
Run the propagation check
The tool queries DNS servers in multiple countries/regions simultaneously. Results appear within seconds.
4
Analyze the results
Green results show the updated record. Red/yellow results show servers still returning the old value. The map visualization shows global status.

Common Use Cases

✓DNS changes — verify that record updates have propagated after modifying DNS settings
✓Domain migration — confirm DNS is pointing to the new server from all regions
✓CDN configuration — check that CNAME records are resolving globally after CDN setup
✓Troubleshooting — identify if DNS issues are global or regional
✓Go-live planning — monitor propagation progress during website launches
✓Email migration — verify MX record changes have propagated before switching email providers

Pro Tips

💡Lower the TTL to 300 (5 minutes) at least 48 hours BEFORE making DNS changes. This ensures faster propagation when you make the actual change.

💡Full DNS propagation typically takes 4-48 hours, depending on the TTL of the old records.

💡Some ISPs ignore TTL values and cache records longer. There's nothing you can do about this — it resolves itself within 48 hours.

💡After confirming propagation is complete, raise the TTL back to a higher value (3600-86400) to reduce DNS query load.
