fwiw, wide-dhcp also allocates a 10/8 address if it doesn't get a response
from a DHCP server.

But this brings up another question:  If the DHCP client only gets NAK
responses should it still allocate a 10/8 address for itself, or should it
take this to mean that it shouldn't be using the network at all?
