Global DNS resolution with DNS pollution detection across multiple resolvers
• Target: the domain name to resolve (e.g. example.com)
• Record type: A (IPv4), AAAA (IPv6), MX (mail), TXT, CNAME (alias), NS (name server)
• Result: DNS resolution result, response time, and authoritative server
• Nodes: pick specific nodes; defaults to all available nodes
A DNS lookup queries your domain's records from DNS resolvers around the world and returns the result and response time seen from each region. Comparing regions surfaces cases where resolution differs by location, helping you confirm a record has taken effect everywhere.
A, AAAA, MX, TXT, CNAME and NS record types are supported. It is commonly used to verify that resolution config has propagated globally, investigate propagation delay after switching DNS or changing a record, and compare results across regions.
This is usually expected: geo-aware DNS returns a nearby IP based on the requester's location, and CDNs do similar steering. Multi-location lookup is precisely how you confirm that steering behaves as intended.
DNS is cached (TTL), so resolvers worldwide only update once the old record expires, which can take minutes to hours. Multi-location lookup lets you watch the new record propagate region by region.
Common types are supported: A (IPv4), AAAA (IPv6), MX (mail), TXT (text), CNAME (alias) and NS (name server). Choose the one you need.
First confirm the record type exists and the TTL isn't too short; if only one region looks off, it may be that resolver's cache or steering — verify reachability with a multi-location ping.
