I think, and I could be wrong:

- if we can't reach DNS, we keep trying until we do
- if we get an authoritiative "That site doesn't exist" we move on
- if the interface is unavailable it will be added to the list when
  it comes up.

If we know the IP of the remote machine, it is added to the association
list.

A local interface is a NIC on the local machine.

There are a bunch of pieces here, DNS, NICs, and routing.

I'm pretty sure it works - what documentation says it doesn't?
