We're still using v4 because we can, because there has been no 
compelling business case to justify spending time on something that 
isn't necessary just right now, especially given the not insignificant 
changes between v4 and v6.  There is nothing on line that isn't 
accessible over IPv4 so there has been no critical app outside the 
infrastructure to spur such changes yet either.

We can all sit here and say "Hey we're running out of addresses, we must 
switch" but until we've run out you're not going to convince the large 
majority of operators, who lets face it are traditionally lazy^W^W 
cautious people , to do anything.
