[ale] dhcpd to multiple vlans from one server

[Michael Trausch]

ISC dhcpd will hand an address out based on the interface it came in on. If if eth0 has 203.0.113.1/25 and eth1 has 203.0.113.129/25, and the DHCP server is authoritative for those two subnetworks, then when it receives a request on eth0 for an address it will issue an address in 203.0.113.0/25; when it receives a request on eth1 it will issue an address in 203.0.113.128/25.

I don't want to spawn a bunch of servers and if I can do it with a single interface that would be ideal.  If I have to go with eth0.0, eth0.1, etc that's a good second choice.
