Did the usual man commands before I sent the email.  It is not clear how
it can be done.

I don't see why not, although I'm not reading the source code right
now.  But the client can create a dhclient.conf file and use it to send
out a host identifier.  That identifier can be unique per IP address,
but I don't believe it has to be unique per originating MAC address.
So you could create the client config file on the fly, run dhclient
specifying that config file, and you should get the IP address that you
want.  Also, different VLANs or LANs for that matter may have different
DHCP servers.  You could also just keep all the information in one
dhclient.conf file and specify the info per interface name.  man
dhclient.conf is your friend.
