• 6.11 RC4 docker ipv6

    Hi

    Before 6.11, docker containers got IPV6 address based on the IPV6 prefix and the container mac address as suffix (EUI-64) (docker using macvlan)

    after 6.11RC4 (the first RC I installed) the containers get IPV6 address based on prefix and ::2/::3 (etc) suffix.

    how can I restore old behaviour?

     

    Thanks in advance

    Not a bug.

    Docker changed the IPv6 behavior and made it the same as IPv4 behavior.

    This means Docker itself hands out IPv4 and IPv6 addresses to containers.

    You still have the ability with macvlan (ipvlan) to set your own IPv4/IPv6 address.

    Thanks

    I still don't understand how to make it use the mac address as suffix like before

    Because my prefix isn't fixed and changes upon renew, I can't use it in docker template
