How many resolvers are checked?

10 resolvers across different geographic regions: Cloudflare, Google, Quad9, OpenDNS, AdGuard, NextDNS, DNS.SB (Asia), Mullvad (Europe), BlahDNS (Japan), and CanadianShield (Canada).

What does the consistency rate mean?

The consistency rate shows the percentage of responding resolvers that returned the same record set. 100% means all resolvers agree. Lower values indicate the change is still in progress or some resolvers are serving stale cached data.

How long does DNS propagation take?

Propagation speed depends on the TTL of the old record. A low TTL (e.g., 300 seconds) spreads changes in minutes. A high TTL (e.g., 86400 = 24 hours) means resolvers may cache the old record for up to a day.
