Sounds like your DNS will be assigned via DHCP leases?  If so, you
probably don't want to muck with that too much or things will break :)

Just drop references to all your local machines into /etc/hosts.

That'll let you ping them easily/simply through whatever aliases you
feel are appropriate, and scales just fine up to 5-10 machines before
getting very cumbersome; internal DNS is definitely an option, but its
going to be 50x more work to setup and requires careful maintenance.
