Regarding "ipecho.net"

Please note that this is a free service, provided as-is with out any warranty.

I know the links have to be consistent so they will probably never change, I'll also try to keep the uptime as close to 100% as possible, but again, I can't offer any warranty for anything and I reserve the right to do whatever I please with it, so you're using the service at your own risk.

If you're planning to use this service in an application you might consider using this link instead: http://ipecho.net/plain

PS: Please don't abuse the system, try to cache the IP for a reasonable amount of time before doing another request, so everyone can enjoy it.
