Everything we can tell about your address, from registry data to routing.
Real tools for real network work. No sign-up, no limits for normal use.
Clear explanations of the protocols and numbers behind every connection.
Routing, registry and location data are compiled by us from public sources every 24 hours. Missing data is shown as missing.

IP geolocation is an estimate. We show the source of each field and never imply precision we don't have.
From typing a name to getting an address: resolvers, root servers, TLDs, caching and TTLs, in plain language.
