Throwing IPv6 in the mix does blur the distinction between internal
and external.  In the blueprints, internal and external have more to
do with whether we're dealing with the name/IP mapping internally to
Neutron or externally to Neutron by integrating with an external DNS
service.  In other words, are DNS entries being consumed by other VMs
on the same network from the dnsmasq server or are they being consumed
external to the network from DNSaaS.

This is the type of question that I was looking forward to to help
flesh out the blueprints to make them IPv6 friendly.  Thanks for

I don't think that we need a separate blueprint as I think that IPv6
will be worked in to the current Neutron architecture.  Sean Collins
made one comment on my blueprint that IPv6 addresses are being
inserted in to the dnsmasq host file.
