Public bug reported:
Hello,
We have an cloud service based on Openstack, we have provide IPv4 (dhcp) and
IPv6 (static),
on ubuntu 18.04 we detected that when is parsed instance-data.json it take info
only for IPv4 and not get static records for IPv6. And related to this it not
generate config for IPv6 we tested with netplan and ENI (ifupdown), all data in
instance-data.json are present in the file.
