We should call this NetworkInterface.

Done.

I think we should add a flag here to filter out link local addresses as well. It
should probably filter out by default

  ...
  bool includeLinkLocal: false});
  ...

With IPv6 the link local address is always present even if there is a routeable
address. For IPv4 they normally go away after an routable address has been
assigned.

For IPv6 it is fe80::/10 and for IPv4 it is 169.254.1.0 to 169.254.254.255. See
http://en.wikipedia.org/wiki/Reserved_IP_addresses.

Alternatively (and maybe better) add an isLinkLocal to the InternetAddress and
make sure that these addresses are always last in the addresses list.
