An excellent thought-provoking post, although in the end I somewhat disagree. From the point of view of the network, the nodes in the graph are attachment points, not hosts. Attachment points are where the network stops. We do have names for those points without invoking node identifiers -- according to <http://trac.tools.ietf.org/group/irtf/trac/wiki/RRGTerminology> they are called locators. Of course forwarding functions will use whatever they want as input, including things that some people call "identifiers", but that extra information is not necessary to describe topology.
Well, for the most part we seem to be using locators to name the edges of the graph, not the nodes. If we only have locators, it makes it very challenging to describe topology. How do you deal with the case where there are two nodes that are both connected to two edges?
