making the host ("interface ID" in IPv6-speack) to be fixed length,
with bigger bitwidth, makes IPv6 address independent from the hardware
interface layer.
today, i see the following horror story a lot:
- use like /28 or something for an IPv4 subnet
- there are 15th computer installed, no room for the new computer
- renember and get /27
- repeat it with (prefix length + 1)
- repeat it with (prefix length + 2)
- ...
today the most expensive cost is the human labor cost. one less IT
guy = happier management level.
