Checking IP addresses and geo location is important to anyone who ever tried a VPN. There is a well known, free to use, relatively uncluttered website that provides that service: freegeoip.net
They also provide machine-consumable API:
freegeoip.net probably fell victim to its own popularity and the service is often unavailable because of overload.
Since we need reliable service both internally and for users, Fruho provides its own geo location API. There are also some differences:
https://fruho.com/ip # Just your external IP address, plain text, nothing more
https://fruho.com/loc?as=json # Your IP's geolocation
https://fruho.com/loc/22.214.171.124 # Given IP's geolocation, plain text
https://fruho.com/loc/126.96.36.199?as=json # Given IP's geolocation
As you can see after clicking the links above the JSON variants produce much simpler answer with minimum essential data to geolocate IP address.
There is also a version for humans: fruho.com/geo
Feel free to use, but not abuse. If in doubt contact us.
