Description Maciej Szulik 2021-05-04 19:48:50 UTC 
In https://github.com/openshift/origin/pull/26054 we temporarily disabled the following tests:

[sig-network] Services should be possible to connect to a service via ExternalIP when the external IP is not assigned to a node
[sig-network] Networking IPerf2 [Feature:Networking-Performance] should run iperf2
[sig-network] HostPort validates that there is no conflict between pods with same hostPort but different hostIP and protocol

example failures can be noticed in:

Comment 1 Maciej Szulik 2021-05-25 14:03:37 UTC 
In https://github.com/openshift/origin/pull/26178 I'm adding one more:

[sig-network] Networking should provide Internet connection for containers

which seems to be a new test coming from 1.21.1 but most likely similar issue as the others.
Comment 3 Arda Guclu 2021-06-21 12:53:55 UTC 
Below tests are also failing due to IPFamily is incorrect in IPv6.

\[sig-network\] Conntrack should be able to preserve UDP traffic when server pod cycles for a ClusterIP service
\[sig-network\] DNS should provide /etc/hosts entries for the cluster
\[sig-network\] DNS should provide DNS for ExternalName services
\[sig-network\] DNS should provide DNS for pods for Hostname
\[sig-network\] DNS should provide DNS for pods for Subdomain
\[sig-network\] DNS should provide DNS for services
\[sig-network\] DNS should provide DNS for the cluster
\[sig-network\] DNS should resolve DNS of partial qualified names for services
\[sig-network\] DNS should resolve DNS of partial qualified names for the cluster
