In https://github.com/openshift/kubernetes/pull/641 which brings k8s 1.21 I disabled all of IP dual stack tests, since the current setup we have is not supporting it.
Similar skips were added in https://github.com/openshift/origin/pull/26039
(The tests were already skipped, but the skip rule is being moved from [Disabled:Alpha] to [Disabled:Broken], since the feature is no longer alpha.) https://github.com/openshift/origin/pull/25818 adds support to openshift-tests for autodetecting whether the cluster is IPv4/IPv6/dual-stack, and once that merges we can merge https://github.com/openshift/kubernetes/pull/565, which un-annotates the tests, while also explicitly skipping them in the local openshift/kubernetes e2e.
