See an example file below, with three subnets.  Note that the machine 
name -> IP mappings are defined in DNS in my case, and that DNS server 
happens to be on the DHCP server machine.  I suspect that /etc/hosts 
entries on the DHCP server would work as well, but I haven't tested that 
configuration.
