option 82

Hi,

My dhcpd.leases file looks like this:

lease x.x.x.x {
  starts 4 2006/06/15 14:31:02;
  ends 5 2006/06/16 14:31:02;
  binding state active;
  next binding state free;
  hardware ethernet 00:30:1b:13:51:0d;
  uid "\001\0000\033\023Q\015";
  set circuitID = "192.168.128.62:1-4-20-0-adsl-1-32";
  client-hostname "winxp";

This is what I did:
I assign IP based on circuitID which is a port on DSLAM  and it is unique.

but

If a customer changes MAC address (replaces ethernet card in computer) this 
stops working which is normal because there is a lease entery with a 
different MAC address and the customer would have to wait until that lease 
expires.

This is what I want to avoid, I would like to make dhcp server that flexible 
if the customer changes MAC address that this would still work.
Like I said before I would lock that IP to the DSLAM port which is in OPTION82
(circuitID).

Do you have any suggestions how could I solve this problem?

Regards,
Micko
