Hi Trevor. See http://www.comptechdoc.org/independent/networking/guide/netdhcp.html for a basic treatment of the issue.

You use the global broadcast address for DHCP which is 255.255.255.255 as the source and 0.0.0.0 as the destination. (I have seen some DHCP servers use the subnet broadcast address which would be 255.255.0.0 for a class B subnet, but it proved to be problematic.)

DHCP is a broadcast protocol, given the fact that you don't actually have an address on the subnet yet. You would issue a DHCPREQUEST on destination port number 67 using 68 as the source port. Clients always use 67 and servers always use 68.

Thanks for the info Bob. Very helpful.

Now I just need to figure out how to make these requests from Rev... Anyone know how to do this?
