Steps to reproduce:
1) Create network with ipv6 subnet.

# neutron net-list
+--------------------------------------+------+-------------------------------------------------------+
| id                                   | name | subnets                                               |

+--------------------------------------+------+-------------------------------------------------------+

2) Create instance with 3 nic
# nova boot \

	--user-data=/root/cloud-config \
	test

# nova list

Logon to instance, mount configDrive:
# mount /dev/disk/by-label/config-2 /mnt/

Actual result:
# cat /mnt/openstack/latest/network_data.json | python3 -m json.tool

        }
    ],
    "services": []

network_data.json provide information about ipv4 adresses only.

Expected result:

network_data.json provide information about all ip adresses.
