About the DNS Propagation Checker
The DNS Propagation Checker queries 20+ global public DNS resolvers in parallel to show exactly how a DNS change is spreading around the world. Every time you update an A, AAAA, MX, CNAME, TXT, NS, or CAA record at your registrar or DNS host, recursive resolvers refresh their caches on their own schedule — driven by the record's TTL. A worldwide propagation check makes it obvious which resolvers already return your new value and which are still serving the old one, so you can plan a cutover or wait out a stale cache with confidence.
We dispatch DNS-over-HTTPS (DoH) queries in parallel to Cloudflare 1.1.1.1, Google 8.8.8.8, Quad9, OpenDNS, AdGuard, Comodo Secure DNS, CleanBrowsing and major regional providers across North America, Europe, Asia, Oceania and South America. Because queries run on Cloudflare's edge network — not in your browser — you sidestep CORS, corporate proxies, and ISP-side caching, so answers are truthful and full worldwide results usually return in under two seconds.
Use the propagation checker when migrating a domain, switching hosting providers, rotating mail servers, cutting over to a new CDN, verifying a DNS-based SSL/ACME challenge, or debugging an outage. If some resolvers show the correct value and others still serve the old one, that isn't a bug in your DNS host — it's normal TTL-driven behavior. Lower TTLs 24 hours before a planned change to make propagation feel instant.
Enter the required value in the input field above (domain, IP, URL, or text depending on the tool).
Click the action button to run the check — results are computed instantly from our edge network.
Review the parsed output, key fields and any warnings shown in the result card.
