ifconfig.co: Simple IP address lookup service

A simple service for looking up your IP address. This is the code that powers http://ifconfig.co

Basic usage

The usual suspects

$ curl ifconfig.co
127.0.0.1
$ wget -q -O - ifconfig.co
127.0.0.1

BSD fetch

$ fetch -q -o - ifconfig.co
127.0.0.1

Pass the appropriate flag (usually -4 and -6) to your tool to switch between IPv4 and IPv6 lookup.

Features

An excuse to use Go for something
