Comment 6 for bug 1786799

@Neils, I wanted to run an idea by you.

What if you could set a particular space to be the default to use when assigning IP addresses? (If you're not familiar with spaces, they're a way to assign a particular "tag" to a VLAN in MAAS to indicate its purpose. Juju and other tools can use spaces as hints or instructions about what networks it's okay to bind a particular service to.)

For example, in your case, you might have a 'provisioning', 'intranet', and 'storage' space. Then you could set your 'intranet' space to be the default space to use for providing DNS names. With each of your VLANs in MAAS labeled with a particular space, MAAS could better infer which to use for the default DNS name - without the need to manually assign default IPs on a per-node basis (which seems a bit cumbersome).

Thoughts?
