So as to resolve hostnames in the LAN, no matter how small, without
having to maintain a separate /etc/hosts on each machine

Yes, if you run your private dns as caching.

Uh... well for a private LAN you can fake authority for whatever you
want (i.e.  my.funny.little.home.lan), provided you spend some time
studying the documentation. If you want to run your real
(i.e. reachable from outside) domain, you must register it and your
official authoritative nameservers (remember you need at least 2 of
them) must have fixed IP addresses.
