Hello. I have 4 Mikrotik CCR’s (2x 1036-12g-4s and 2x 2116-12G-4S+), and they set up to give IPv6 subnets /64 for users. But some users have buggy routers, which change constantly DUIDs and IAIDs. So CCRs constantly give them different subnet. Is there ability to teach DHCPv6 server to give subnet only by MAC address of client, not IAID or DUID?
