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 ;-)
