About Us
Confidence that your DNS has truly propagated
isPropagated is a free DNS propagation checker built for people who need a definitive answer, not a guess. When you change a DNS record, the update reaches resolvers around the world at different speeds. We run a single test query for flag propagation check across independent global public DNS networks at once and line up the results so you can see exactly where your change is live.
Genuinely independent networks
We query 7 resolvers operated by different organizations on separate infrastructure — Google, Cloudflare, AdGuard, NextDNS, DNS.SB, Alibaba and DNSPod — instead of many labels sitting behind one anycast network.
Records and DNS flags
We compare both the records returned and the header flags (AD, CD, RA, RD, TC), so you catch DNSSEC and resolver issues that a plain record check would miss.
Free, no sign-up, no ads
Every propagation check is completely free. There is no account to create and no advertising cluttering your results.
Why we built it
Traditional DNS checkers often query dozens of geographically labelled servers that actually share the same underlying network, so they return the same cached answer and give a false sense of certainty. We wanted a tool that queries operators who are truly independent of one another, because agreement between separate organizations is a far stronger signal that a record has propagated worldwide.
Whether you have just switched hosts, updated nameservers, added an SPF or DKIM record, or enabled DNSSEC, isPropagated helps you re-run the check until every network reports the new value — quickly, freely and without any noise.
