here is an interesting article:

Largest estimate of all the stars in our universe:
1,000,000,000,000,000,000,000,000
...Number of websites addresses available:
340,282,366,920,938,463,463,374,607,431,768,211,456
Just a thought but I'm assuming this works by adding an extra few numbers to IP adresses. So when these new longer adresses become more common what happens on older games and things like gamespy that won't be updated. Will people still be able to log? Will booting still work on SWBF?
Those are good questions :)
I suspect that things could be mapped from the old system to the new one.
If you have a newer computer and type in IPCONFIG at a command window, you may already see lines in there
for IPv6. So, I think they are trying to keep it compatible, but I can't say for sure.
Typing IPCONFIG gives me an IPv6 address that includes numbers and a % symbol so I'm not sure how that would affect things. I read before that the two systems should be compatible though so lets hope so :)
