[14:39] <smoser> rharper, is there something in cloud-init that says is_ipv6_addr(address)
[14:39] <rharper> cloud-init/net ?
[14:40] <smoser> or something like that. given a list of addresses i want to filter out the ipv4 ones and the ipv6 ones.
[14:40] <smoser> yeah.
[14:40] <rharper> lemme look
[14:42] <rharper> smoser: I don't see anything specific, but I think ':' in addr is sufficient
[14:42] <smoser> k
[18:09] <harlowja> rharper https://github.com/openstack/oslo.utils/blob/master/oslo_utils/netutils.py#L84
[18:09] <harlowja> https://github.com/openstack/oslo.utils/blob/master/oslo_utils/netutils.py#L99
[18:09] <harlowja> if u want another way
[18:10] <harlowja> but that uses netaddr ...
[18:20] <rharper> harlowja: I wonder what netaddr does?
[18:20] <harlowja> thou shall look at the code?
[18:21] <rharper> yeah, looking now
[18:29] <rharper> harlowja: looks like a fancier versision of checking for '.'  ipv4 and ":" in ipv6
[18:29] <harlowja> nice, ha
[18:29] <harlowja> where's the code for that
[23:21] <smoser> rharper, i just pushed to bzr+ssh://bazaar.launchpad.net/~smoser/cloud-init/trunk.smartos-fabric/ with what we'd worked on.
[23:33] <Nivex> Hi folks. I'm trying to boot an Ubuntu 16.04 Cloud image on an IPv6-only VLAN. I have the datasource set to local so it doesn't need to talk to the network, but it still hangs on Raise network interfaces for 5 minutes.
