  The same thing happens when companies buy other companies.  The worst
I've seen (so far) is 3 layers of NAT, all using Net 10.  It works, and
it plays hob with equipment trying to have "internal" IP addresses.  But
hacking selected server equipment is usually cheaper than changing
hundreds of switches and thousands of end hosts.
