Turn off the dhcp in the router and use the /etc/hosts file to do the 
resolving.  You can use the same hosts file throughout your local 
network.  I've been doing that here for 6 or 7 years.  You'll have to 
assign the local ip address per machine in 
the /etc/sysconfig/network-scripts/ifcfg-eth0 scripts also, which 
will give a fixed address for that machine.  To me, dhcp on a small 
home network, or even on an 80+ machine business internal network is 
a waste of time and resources.  But then thats just my opinion too.

One could even setup a cron job on those machines that have a cron, to 
grab the master copy of the hosts file and refresh it if the network 
is being constantly changed.  That would take a load off the IT guy, 
who usually has his own pool of alligators to wrestle.
