Frequently Asked Questions

How long does DNS propagation take?

DNS propagation typically takes 1-48 hours, depending on TTL values and caching. Our tool helps you monitor progress in real-time.

Why might DNS propagation be inconsistent?

Different DNS servers cache records for different periods based on TTL. Some servers may still have old cached values while others have updated.

Which DNS servers do you check?

We check major DNS providers including Cloudflare (1.1.1.1), Google (8.8.8.8), Quad9 (9.9.9.9), OpenDNS, and regional servers in US, Europe, and Asia Pacific.

How can I speed up DNS propagation?

Lower your TTL values before making changes, wait for old TTL to expire, then make changes. After propagation, you can increase TTL again for better caching.
