oc get po openshift-apiserver-operator-5fbd9ddd8d-2d2sd -n openshift-apiserver-operator -o jsonpath='{ .status.hostIP }' fd2e:6f44:5dd8::117 I think that this is a configuration problem, the apiserver log in the bootstrap show > I0208 13:09:03.980230 1 flags.go:59] FLAG: --advertise-address="<nil>" then it defaults to the IPv4 address using in the interface with the default network > I0208 13:09:03.981891 1 server.go:697] external host was not specified, using 192.168.123.125 if we want to use the IPv6 address of the interface in the default network we need to pass "::" to the --advertise-address flag advertise-address is set by config observer owned by networking team. Moving component. Actually, it is not due to an observer, but the advertise address is the node IP, compare https://github.com/openshift/cluster-kube-apiserver-operator/blob/master/bindata/v4.1.0/kube-apiserver/pod.yaml#L57.
