Does not handle default ipv6 localhost entries on OS X

[e110c0]

on Macs there generally is a special entry in /etc/hosts:

fe80::1%lo0 localhost

while trying something like this:

dns.resolve4('www.google.com', function (err, addresses) {
  if (err) throw err;

  console.log('addresses: ' + JSON.stringify(addresses));

});

it throws: ipaddr.js:374 throw new Error('ipaddr: the address has neither IPv6 nor IPv4 format');

The problem can be avoided by removing that entry from /etc/hosts, but might occur in other scenarios as well. Not sure how to handle this strange entry appropriately.

for now I'm guarding against the interface portion of this, but I think perhaps I should send the issue upstream to ipaddr.js
