Couldn't let this one slide...

Bits grow exponentially.  Saying IPv6 is 4x IPv4 isn't really accurate
unless you're counting bits.

A 128-bit address space gives you over 340 undecillion (3.4 * 10^38)
unique values compared to the pathetic 6 billion or so of a 32-bit
address space.  Certainly more than 4 or 5x ;-)
