IPv6 IP pollution
IPv6 gives you a huge address space where you can use anything from 0-f in eight notations to create an address. This allows IPv6-users do create creative IPv6 addresses which are viewed as IP pollution by some dead-inside system administers. Other more hacker-minded people see create IPv6 addresses as another form of the playful cleverness which underpins hacker culture.
Why "IP pollution" Is Bad
The reasons why the simple act of idling on IRC with a "IP Pollution" address is a bannable offense at tunnel brokers like SixXS is beyond our understanding. We can only speculate that the Google and IBM employed people who run that service are dead inside.
Why People Use "IP Pollution" Addresses
When Rome was still a functioning republic, Roman judges would always ask the simple question:
Who benefits from this crime? in original Latin: "cui bono?"
When asking this simple question, we see:
- It's fun.
- It shows that some effort was made to configure a machine to use a custom IP
- Want-to-be 1337 teens who may want to look cool can use a IP pollution IPs to do that. They benefit by getting dozens and dozens of n00b fans.
Apart from that? Who knows.
It must also be noted that if you have a /48, which was very easy to get (lots of) once upon a time, you could play with provided with:
...where Y are parts of the IP that's given to you while X are parts you can choose. If you only have a /64 then you've only got 4 blocks of 4 to decide:
Now, the obvious thing to do when you have a huge address space to play with is to use :1::1. But that's no fun. So people (those bastards?) IP-pollute.
Some examples of this are:

Using beef:cafe as part of an IPv6 IP was highly recommended by the BT exact IPv6 Tunnel Broker in their howto]]. BT exact seized their tunnel broking operations sometime between 2010 and 2015.
