What it does
DNSAudit's propagation checker compares DNS answers across multiple global resolvers and offers a map and printable or saved results.
DNSAudit’s propagation checker compares a domain’s answers across a fixed set of more than fifteen public recursive resolvers, with a map and saved or printable results. It does not query authoritative nameservers for this check. Different cached answers can persist according to resolver policy and TTL, and a timeout can reflect routing, rate limits or upstream access rather than a missing record. Some providers use anycast, so a “Global” entry is not a single fixed server location. Treat agreement across the displayed sample as evidence about those queries, rather than proof that every client worldwide has refreshed.
