Sorry I don't get you. Isn't it that even with this check is in place, you
would still get "127.0.0.1" address returned by if_enum_by_af()?
Thinking about the NULL address again, I think probably that's a valid
behavior for "ppp" interface, e.g. during initial negotiation and when IP
address is not assigned yet. So I'm not sure if this is a Linux bug.
And regarding the duplicate interfaces that you reported, probably that's
because of IPv6 address?
Cheers
