NodeJS - Custom DNS lookup, fallback to ipv4

I’m trying to solve an issue with nodejs not being able to lookup the ip address when using ipv6 family: 6 in the Https.Agent options.

Error

Error: getaddrinfo ENOTFOUND raw.githubusercontent.com
  at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:66:26) {
  errno: 'ENOTFOUND',
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'raw.githubusercontent.com'

The solution I built is working, but seems very inefficient because I have to repeat the DNS lookup for ipv4 after the first one with ipv6 has failed. Is there a better way to solve this?

Code

function customLookup(hostname, options, callback) {
    return lookup(hostname, options, (error, address, family) => {
        if (error) {
            lookup(hostname, { ...options, family: 4 }, (error, address, family) => {
                callback(error, address, family);
            });
        } else {
            callback(error, address, family);
        }
    });
}
...

return new Https.Agent({
  keepAlive: true,
  family: options.family || 6,
  lookup: customLookup,
});
