IP Location Lookup

Geolocate any IPv4 or IPv6 address to its country, region, city and coordinates, along with the ISP, organisation and AS number behind it.

About IP Location Lookup

Enter an address and IP Location Lookup queries our self-hosted DB-IP Lite databases to return the country and its ISO code, the region or subdivision, the city, and the latitude and longitude, which are plotted on a map. It also reports the AS number and the network organisation that owns the address, giving you both the where and the who of an IP in a single result.

IP geolocation works because addresses are allocated in blocks to networks that register a location for them, and geolocation databases map those ranges to places. The result therefore reflects the network's registration rather than a device's exact position. It is typically accurate to the country and often to the city, but addresses belonging to mobile carriers, VPNs and cloud providers can resolve far from any real user.

Both IPv4 and IPv6 addresses are supported and return the same set of country, region, city, coordinate and network details. Private and reserved addresses have no public registration, so they return no location; only globally routable addresses can be placed on the map.

The lookup runs entirely against local databases on our EU servers, with no third-party geolocation API involved, so the address you check is not forwarded to an outside service. That makes it a privacy-preserving way to investigate an IP from your logs, review the network behind a login attempt, or confirm where a server or CDN edge is hosted.

How to use it

  1. 1Enter any public IPv4 or IPv6 address you want to locate.
  2. 2Press Locate to query the self-hosted geolocation databases.
  3. 3Read the country, region, city and coordinates, plus the AS number and organisation.
  4. 4Use the map to see the approximate position of the address.

Common use cases

  • -Identify the country and network behind an unfamiliar IP found in your server logs
  • -Check the AS number and ISP of an address as part of an abuse or fraud review
  • -Verify where a server, mail host or CDN edge is physically located
  • -Investigate the origin of suspicious traffic or an unexpected login attempt
  • -Confirm an address maps to the region you expect for compliance or routing checks

Frequently asked questions

How accurate is IP geolocation?
It is generally reliable at the country level and often correct at the city level, but it reflects where the IP block is registered rather than a user's exact location. VPNs, mobile carriers and cloud providers can shift the result by hundreds of kilometres.
What is an AS number?
An Autonomous System Number identifies the network operator that announces an IP range on the internet, such as an ISP or hosting provider. This lookup shows the AS number and its organisation for the address you enter.
Can you geolocate an IPv6 address?
Yes. This tool accepts both IPv4 and IPv6 addresses and returns the same country, region, city, coordinates and network details for either type.
Does an IP location reveal a person's home address?
No. IP geolocation resolves to an approximate area tied to the network, not to a household or individual, and cannot identify a specific street address or person.
Where does the location data come from?
Lookups run against the self-hosted DB-IP Lite databases on our EU servers, so no third-party geolocation service is queried and the address you check is never sent to an external API.
