Hi Simon.

Do you think Option 82, is not it?
Really my question is, that whether can I do this with regular ISC DHCP 
config statements
  or options (like hardware ethernet - fixed-address pair) without 
sniffing the DHCP
discover packets or processing the dhcpd.log?
If anybody would a revelant config part, I thank to him.
