Hi, as the documentation sends mixed signals in https://docs.ceph.com/en/latest/rados/configuration/network-config-ref/#ipv4... "Note Binding to IPv4 is enabled by default, so if you just add the option to bind to IPv6 you’ll actually put yourself into dual stack mode." and https://docs.ceph.com/en/latest/rados/configuration/msgr2/#address-formats "Note The ability to bind to multiple ports has paved the way for dual-stack IPv4 and IPv6 support. That said, dual-stack operation is not yet supported as of Quincy v17.2.0." just the quick questions: Is a dual stacked networking with IPv4 and IPv6 now supported or not? From which version on is it considered stable? Are OSDs now able to register themselves with two IP addresses in the cluster map? MONs too?
