Usage:

myip.blue is available over http/80 or https/443, and resolves to ipv4 and ipv6 addresses.
v4.myip.blue only resolves ipv4.
v6.myip.blue only resolves ipv6.
myip.blue/json returns json-formatted output.
myip.blue/ip returns only a text string of the client IP address.

If user-agent begins with 'curl' or 'wget' at /, the behavior also defaults to the simple text string. For more detailed information while using curl, use the /json endpoint.

cf.myip.blue is similar functionality but as seen through the Cloudflare edge.
