http.request option "family: 6" doesn't enable request over IPv6

Version: 5.5
Platform: Ubuntu 14.04.1
Subsystem: http(s)

Seems like family option does nothing with actual DNS resolve to ipv6.
Problem is internal server should only use ipv6. So, instead of

https.get({
    hostname: 'cloud-api.yandex.net',
    path: '/v1/disk/resources?path=/',
    family: 6,
    port: 443,
    protocol: 'https:'
}, (res) => {
    console.log(res);
}).on('error', (e) => {
  console.log(`Got error: ${e.message}`);    // Got error: connect EHOSTUNREACH 213.180.204.127:443
});

i should write

dns.lookup('cloud-api.yandex.net', { family: 6 }, (err, addr, family) => {
    https.get({
        hostname: addr,
        path: '/v1/disk/resources?path=/',
        port: 443,
        protocol: 'https:',
        headers: { host: 'cloud-api.yandex.net' }
    }, (res) => {
        console.log(res);
    }).on('error', (e) => {
      console.log(`Got error: ${e.message}`);
    });
});
