IP.cx

Very simple «Whats my IP?» service mostly inspired by icanhazip.com but significantly shorter. It can also detect that you're visiting from - which belongs to - (-) and your timezone is probably -.

Usage is pretty straightforward. Do curl to ip.cx to get your IP as seen from public internet. Use keys -4 or -6 to get IPv4 or IPv6 addres respectively. Host info.ip.cx will return simple JSON object with IP address, ISP, AS number, country and timezone — depending on what is known by CloudFlare geolocation database.
