IP Addressing in Point-to-Point Links

Each of the LANs in the previous diagram is a distinct network (or subnet) for purposes of IP addressing and routing.
 
Not so obvious is the fact that the point-to-point link is also a network (or subnet), albeit one with only two hosts. For example, until recently the Bundoora and Bendigo campuses of La Trobe University were linked as follows:
Point-to-point link is IP subnet
Here we see that subnet 131.172.239.0 has been assigned to the point-to-point link between between the Bendigo and Bundoora campuses.
