Last modified: 2017-11-28 17:16:24 EST
Description of problem: Panic error found in node log when adding ipv6 as egressIPs to hostsubnet. Version-Release number of selected component (if applicable): v3.7.0-0.147.0 How reproducible: always Steps to Reproduce: 1. Setup multi node env 2. Modify the hostsubnet of any node to add the egressIPs # oc patch hostsubnet node1 -p '{"egressIPs":["fe80::54aa:c3ff:fe26:2e76"]}' 3. Check the node log on node Actual results: Panic error about `index out of range`. Expected results: Should not be able to add ipv6 address as egressIPs.

Tested on ocp build v3.7.0-0.158.0, ipv6 addr cannot be added as egressIP. [root@ose-master ~]# oc patch hostsubnet ose-node2.bmeng.local -p '{"egressIPs":["fe80::9400:a1ff:feb5:93b7"]}' The HostSubnet "ose-node2.bmeng.local" is invalid: egressIPs[0]: Invalid value: "fe80::9400:a1ff:feb5:93b7": must be an IPv4 address
