careful with the skip condition this time. Addresses are only not taken into
account if:
- The interface is POINTTOPOINT
- There is no route installed for the address
- The user specified noalias (:0)
and - We are looking at an IPv4 address.
This should be enough paranoia to not cause any false positives.
