Hi Gert,

I see your point. We use a hierarchy in operating a large network, for
example the headquarter assigns an address block to a province, and the
province assigns a sub-block to a city, and administrators in the city
assigns an address to a router. We cannot require an admin to assign an
address with a unique id as they don't know what others use for ids.
Operating the entire network by a single person would be easy but we can
rarely see this case.
