What is IPThing?
  IPThing's primary function is to display the current Wide Area Network IP address of the machine it is being executed on.  This IP address is what uniquely identifies your computer or router on the internet.  There are any number of reasons why you might need to know your WAN address.  You may wish to direct traffic to your machine if you have a web cam or website.  With your IP address you could establish a direct connection with friends and colleagues for collaborations and peer to peer file exchanges.

In addition to displaying your WAN Address, IPTHING will also display the IP addresses of machines on your internal network and provide a few other functions you may find useful.
