Will this work on machines that only have IPv6 configured?

@cjihrig , the listen will fallback to IPv4, when IPv6 failed.
if (address || port || isTCP) {
debug('bind to ' + (address || 'anycast'));
if (!address) {
// Try binding to ipv6 first
err = handle.bind6('::', port);
if (err) {
handle.close();
// Fallback to ipv4
return createServerHandle('0.0.0.0', port);
}
} else if (addressType === 6) {
err = handle.bind6(address, port);
} else {
err = handle.bind(address, port);
}
}

I didn't notice before that this is just for formatting an exception. I don't know how I feel about setting the value artificially just for that, but I'm OK with the rest of the PR.
