This is a rather long standing issue. LibDNS didn't allow to decode empty domain names. Empty domain names were previously only observed with PTR records, but were now also observed in regular queries in authoritative records that include the root nameservers. LibDNS 2.0 mainly adds scalar types has just a few breaking changes. We don't expose it anywhere, so an upgrade is perfectly fine. Fixes #53.

var_dump($githubIpv4);
$googleIpv4 = Amp\Dns\resolve("google.com", Dns\Record::A);
$googleIpv6 = Amp\Dns\resolve("google.com", Dns\Record::AAAA);
$firstGoogleResult = yield Amp\Promise\first([$googleIpv4, $googleIpv6]);
var_dump($firstGoogleResult);
$combinedGoogleResult = yield Amp\Dns\resolve("google.com");
var_dump($combinedGoogleResult);
$googleMx = yield Amp\Dns\query("google.com", Amp\Dns\Record::MX);
