With your network topology in mind, you can use the following guidelines to select a host on which to set up a DHCP server.
The server must:
Run the Solaris 2.6, Solaris 7, or Solaris 8 operating environment
Be accessible to all the networks having clients that will use DHCP, either directly on the network or through a BOOTP relay agent
Be configured to use routing
Have a correctly configured netmasks table that reflects your network topology
