So by "*once you've assigned an IP to a server*" I mean in OCCI, not in the
server. If OCCI knows the server (presumably by MAC address) has a given IP
and your DHCP server can talk to the OCCI backend (or vice versa) then
there's no special case here... if you can support it then do and people
won't have to (but can anyway) configure statics. Have I missed something?
