What you get

What an IP lookup tells you

Field	Meaning
country, region, city	Where the network is estimated to be
zipcode, latitude, longitude	Approximate postcode and coordinates, usually of an area rather than a building
timezone	IANA time zone, e.g. Europe/Athens
isp, organization	Who operates the network the address belongs to
asn	Autonomous system number of that network
risk.is_ai / is_crawler / is_scanner	Whether the address is published infrastructure of an AI crawler, a search or SEO crawler, or an internet scanner

Accuracy

IP location is an estimate of where a network is, not where a person is. Country is usually reliable; city, postcode and coordinates are approximate, and VPNs, proxies, mobile carriers and cloud providers can place an address far from its user. Each uncached lookup merges answers from several independent providers, and a field stays empty when none of them has a value.

Verified bot signals

Anyone can send a GPTBot or Googlebot user agent. The bot signals look at the address instead: they are set only when it is in the IP ranges an operator publishes, or passes forward-confirmed reverse DNS for that operator. See every operator and how it is checked on the bot signals coverage page.

Fair use

This page allows 30 lookups of other addresses per hour from one IP address. Looking up your own IP doesn't count. Private and reserved addresses are answered without a lookup.

FAQ

IP lookup questions

What does an IP lookup show?

For a public IPv4 or IPv6 address: country, region, city, postcode, approximate coordinates, time zone, the ISP and organisation that operate the network, and its autonomous system number (ASN).

How accurate is IP geolocation?

It is approximate. Country is usually reliable; city, postcode and coordinates are estimates. Each uncached lookup merges answers from several independent data providers, and fields no provider can answer are left empty rather than guessed.

Can I look up a domain name?

Yes. Enter a domain such as example.com and it is resolved to its first IPv4 address (A record), which is then looked up.

What is an ASN?

An autonomous system number identifies a network operated under a single routing policy, such as an ISP, a cloud provider or a large company. It tells you whose network an address belongs to.

What do the AI crawler, search crawler and scanner flags mean?

They show whether the address belongs to infrastructure an AI company, search or SEO crawler, or internet-scanning project has published as its own, using the operator's IP range files or forward-confirmed reverse DNS. A user agent alone never sets them.

Why can't I see a location for 192.168.x.x or 10.x.x.x?

Those are private or reserved addresses used inside local networks (or for documentation and testing). They are not routed on the public internet, so they have no location or ISP.

How many lookups can I do?

This page allows 30 lookups of other addresses per hour from one IP address. For more, a free API key gives you 1,000 requests a day.
