Happy World IPv6 Day!

Companies all over teh internets are testing their IPv6 deployments as we speak (http://www.worldipv6day.org/). In general this is a good thing, but one of the many changes in the Internet Protocol destroys something near and deer to my geeky child hood. Let me explain with the following IRC re-enactment that played out over and over in my youth.

Some_D-Bag: You're such a n00b, you suxor!
Me: Whatever, go away.
Some_D-Bag: I'll show you, I'm 1337!
Me: I told you, go away.
Some_D-Bag: I'll show you I've got skillz. Whats your IP
Me: Ooooooohh, I'm scared. Do you worst, idiot. I'm at 127.119.84.217
Some_D-Bag has left #some-chan

In IPv4, the entire 127.0.0.1/8 is considered loopback. In IPv6, there is only one loopback address defined: 0:0:0:0:0:0:0:1. So that little trick won't work. Oh well.
