Ouch.  That's why you use DNS (of course...you knew that from later comments)

If you statically assign the IP addresses, then it wouldn't have to be
updated except when a server is changed/added/removed.  I've done this in
the past with scripts that can be scheduled to run on each machine that
pull a master hosts file from a designated main server, but it's far less
reliable and desirable than running DNS.

You would normally set up a DNS server to provide local name resolution and
set it to go to your external DNS servers for addresses outside your local
domain.  (It gets a lot trickier with "split DNS" if you're running your
own outward-facing DNS server, but you're not doing that now, so don't
start.)
