Data sources

Where every answer comes from.

Each value on peekip names its source. This is the full list, with the version we are using right now. A source we couldn’t load says “Not checked” on the page rather than a guess.

Attribution

IP Geolocation by DB-IP — DB-IP Lite databases are licensed under CC BY 4.0. DB-IP describes Lite as having reduced coverage and accuracy compared with its paid data, and it publishes no accuracy radius, so we never draw one.

IP address data is powered by IPinfo — IPinfo Lite is licensed under CC BY-SA 4.0. It is shown only when the IPinfo source was actually checked.

Place names for the lens and distances come from GeoNames (CC BY 4.0). IANA registries are CC0. Provider IP ranges are published by each provider for its customers and carry no licence; we cite each file and its timestamp and imply no affiliation.

Rules we apply to the data

  • Hosting network: an address is labelled hosting when it is inside a cloud or CDN provider’s published ranges, or its DB-IP network is one of 34 hosting operators on our curated list (checked against DB-IP’s operator name). VPNs usually exit from such networks; a hosting address is not proof of a VPN.
  • Registry country is where a block is registered, which isn’t always where it is used. ARIN records usually carry no country, so the registry doesn’t vote for those.
  • Geofeeds are only trusted for addresses inside the registry record that links them (RFC 9632), are fetched over HTTPS with an 8 MB cap, and are cached for 7 days.
  • Device clock is read in your browser and only ever counts as a weak signal: a time zone fits a set of countries (IANA zone1970.tab, zone.tab and backward).
  • Carrier-grade NAT is only claimed for addresses in 100.64.0.0/10, or for a provider that documents it.
  • Not used: MaxMind GeoLite (its licence doesn’t allow showing it), RIPEstat, PeeringDB, RouteViews, CAIDA, Tranco and Spamhaus.

Registry answers come live from each regional internet registry over RDAP and are subject to their terms. See also our policy.
