So nobody ever needs a name/ip mapping to the nodes anyway?

I thought you said you _were_ running a DHCP server. And the part
that confuses me is why anyone would split the addressing and naming
authority into something that doesn't match the topology. That is, if
you are working together with whoever runs the DNS I'd expect the
name/IP mapping to be coordinated, probably with a central DHCP as
well, or if your network management is delegated to you, then you'd do
both independently. But if you are running something unusual that
doesn't care about names or DNS then it doesn't matter...
