IP2Location Erlang Module

This Erlang module provides a fast lookup of country, region, city, latitude, longitude, ZIP code, time zone, ISP, domain name, connection type, IDD code, area code, weather station code, station name, mcc, mnc, mobile brand, elevation, usage type, address type and IAB category from IP address by using IP2Location database. This module uses a file based database available at IP2Location.com. This database simply contains IP blocks as keys, and other information such as country, region, city, latitude, longitude, ZIP code, time zone, ISP, domain name, connection type, IDD code, area code, weather station code, station name, mcc, mnc, mobile brand, elevation, usage type, address type and IAB category as values. It supports both IP address in IPv4 and IPv6.

This module can be used in many types of projects such as:

  • select the geographically closest mirror
  • analyze your web server logs to determine the countries of your visitors
  • credit card fraud detection
  • software export controls
  • display native language and currency
  • prevent password sharing and abuse of service
  • geotargeting in advertisement

The database will be updated in monthly basis for the greater accuracy. Free LITE databases are available at https://lite.ip2location.com/ upon registration.

The paid databases are available at https://www.ip2location.com under Premium subscription package.

As an alternative, this geolocation module can also call the IP2Location Web Service. This requires an API key. If you don't have an existing API key, you can subscribe for one at the below:
