As someone else mentioned even if you did a /31, those addresses aren't
on the same network...
254 & 1 == 0
254 & 2 == 2
Hence different networks.. the other thing is that you can't have a /31
due to the fact that one ip w/ all the node bits set is the broadcast
for the network causing other sorts of troubles... the smallest usable
network is a /30...
