on my systems (private network),  I have all the local hosts use DHCP.  
I set the MACs within the DHCP server to hard code IPs of key servers i 
want to be static.  I then manage a centralized host file that i share 
amoung hosts.  Since I'm only managing a hand full of servers--less than 
10, this is very managable.
