Hi Randy,

The first time they had 256 addresses (8 bits) right? That's where the
original /8 assignments in IPv4 came from, the folks listed back in
RFC 758 who had an IP address before IPv4. IPv4 jumped from 8 bits to
32 bits. Which when you think about it is the same ratio as jumping
from 32 bits to 128 bits.
