Excellent, identification by MAC address was often requested. Thanks
for this software.

like other people we had the problem that existing DHCPv6 servers do
not evaluate the MAC address of clients, following RFC 3315.

I'm not convinced that it is RFC's fault. The only thing I find in RFC
3315 is (section 9) "DHCP servers use DUIDs to identify clients for
the selection of configuration parameters and in the association of
IAs with clients." I read it as "a compliant DHCPv6 server MUST
recognize DUID and identify clients this way" which does not logically
imply that it cannot identify clients by other means as well.
