Questions about Geolocation Use | IP Geolocation API | WhoisXML API


How extensive is your IP geolocation data?

Our IP geolocation database contains circa 3.7B unique addresses in the IPv4 space and undecillions of IP addresses in the IPv6 space. This corresponds to 99.5% of all IP addresses in use, across 17,390,000 IP ranges in 250 countries and 291,103 unique locations.

Which geo data points do you cover?

Our data points include location (i.e., country, region, city, latitude, longitude, postal code, UTC timezone, and GeoNameID), ISP, connection type, associated domains, and Autonomous System (AS) data (i.e., AS number, name, route, domain, and type).

How precise is your geolocation data?

We identify locations with precision up to the city and postal code level but do not specify the street name. Latitude and longitude coordinates normally point to the center of the city.

How can I find a mobile phone's geolocation or the owner of an email address?

Our IP Geolocation API service allows you to identify a geographical location of a specified IP address, email address, or domain name. However, we operate with only public IP addresses (opposite private, which most phones have) and MX servers for email addresses.

Therefore it is impossible to locate a mobile phone or connection point of an email address owner this way. In such cases, you should contact the respective carrier or ISP.
