how can you apply an hd ration when you do not know their actual
need. whatever it may be, i have this wild guess that it is not
for 2^48 hosts.
and why not to a /40, for byte alignment? or a /32 for half-word?
i don't know what we're smoking here, but i know what we're
burning. address space. and it is not an infinite resource.
