I've always wanted to try, but never got around to, keying off the PXE "vendor-class-identifier" option in the bootROM DHCP request.

If it works, perhaps it should be the default in Cobbler. Here's some HOWTOs:

Also (though this really isn't quite as useful except in smaller home-lab sort of cases, I think), you can configure ISC dhcpd to listen on only one interface.   

 

Another option is to get the main DHCP admins to set "next-server" and "filename" for your subnet to point at Cobbler so you don't have to run your own DHCP, but this is not always possible.

to be safe, you can also disable any dhcp helpers on your switch ports

that service you subnet.

 

This is only true if your network is on a seperate vlan or physical

network. Multiple subnets can coexist on a single vlan, in which case

you would surely cause issues on the LAN.

 

You could also configure a dhcp server to respond only to known macadresses.
