DHCPv6 still not working as expected.
My ISP enforces all 24 hours a disconnect. IPv4 address and IPv6 prefix is dynamic, but it takes 20 minutes until a new prefix is obtained.
Last working Router OS was v 6.33.6.

By the way, when can we expect a working prefix delegation according to RFC 7084?
Mikrotik and IPv6 ist still a very painful experience.
