It numbers it. But it's less useful than a traditional MAC address as it's not as generally usable after connecting the device to a compatible network. > i believe that an ip -ADDRESS- is an indication of -WHERE- in > the topology a node currently sits, btu the address is not the name. > > so are IPv6 numbers "addresses" or "names"? or some bastard combination > foisted on the poor operations community who is left with trying to > figure it out? :) They're identifiers on the network layer. Names are what hu-mans give services, devices etc. They consist of two parts, a network part and a host part. The network part identifies the topology, the host part identifies the exact place in that topology. It seems we went back to pre-CIDR days with IPv6 and made everything a /64 (at least in 2001::/16). That makes it at least easier to tell the parts apart. -- Niels.
