One way would be to poll your routers' ND tables (like fetching ARP tables in IPv4). As soon as you use relaying you most certainly won't get a useable MAC address from your client, even though it might be possible in the same network segment. (The MAC address is not copied from the wire into the new relayed packet sent by the router to your server.) DHCPv6 uses the so-called client identifier extensively and not the MAC address anymore. So you cannot do any static assignment based on MAC addresses. Kind regards Philipp Kern
