DNS Propagation Checker
Compare DNS answers across multiple public resolvers worldwide.
About this tool
Queries the same record from Google, Cloudflare, Quad9, NextDNS, and OpenDNS resolvers in parallel via DNS-over-HTTPS. If every resolver agrees, your record has propagated. If answers diverge, the change is still rolling out.
FAQ
- How long does DNS propagation take?
- Most modern resolvers respect TTL within a few minutes. Stragglers can take up to the previous TTL value (often 1–24 hours). Lowering the TTL before a planned change shortens the window.
