There's enp0s3 and lo. Both are up, and no, they've no ipv6 addresses (cannot assign them even using ifcfg). ifcfg enp0s3 add fc00::1002/124 results in arping: Unknown host fc00:1002 Error: some host already uses address fc00:1002 on enp0s3. You know the last error message sounds ridiculous. The virtual interface on the host has IP fc00::1001/124 Using ip, it also complains "RTNETLINK answer: Permission denied". Since this's a fresh install, I think I should file a bug.
