DNS propagation
Compare one DNS record across Cloudflare, Google, Quad9, and OpenDNS.
A propagation check asks the same question of four public resolvers. After you change a record, some of them still show the old value until the previous TTL expires.
Pick A, AAAA, MX, NS, or TXT. A row that says no answer means that resolver did not return a record in time. Check again in a few minutes.
DNS propagation FAQ
Why do the answers differ?
A change is still moving through DNS. Resolvers keep the previous record until its TTL ends.
Which resolvers are used?
Cloudflare (1.1.1.1), Google (8.8.8.8), Quad9 (9.9.9.9), and OpenDNS (208.67.222.222).
What does no answer mean?
That resolver did not return the record before the check timed out, or the record is not published there yet.
