That version is fairly old now, you might want to
be looking at an upgrade sometime.
Your fundamental problem is that you need a
unique and persistent identifier for the client.
BY default this is the client-id, or if this is
not supplied by the client (as is the case for
most non-WIndows devices), the MAC address.
Unless you have something else then you are stuck
with the MAC address.
In some networks it's common to use option 82,
Circuit ID, for an alternative identifier. This
is inserted into client requests by the switch or
cable network equipment, and can be used to
assign addresses to clients (with some effort).
If your network can identify clients by an
equivalent to Option 82 (as might be the case if
you have an NTE at the client end into which the
client connects his equipment) then you may want
to search the archives for Option 82. Otherwise I
think you're stuck with MAC address.
