(Perl) DNS Query NS Records
Shows how to perform a DNS query to retrieve NS records.
Note: This example requires Chilkat v9.5.0.96 or later.
use chilkat();
$dns = chilkat::CkDns->new();
$json = chilkat::CkJsonObject->new();
$json->put_EmitCompact(0);
$success = $dns->Query("NS","x.com",$json);
if ($success == 0) {
print $dns->lastErrorText() . "\r\n";
exit;
}
print $json->emit() . "\r\n";

$i = 0;
$count_i = $json->SizeOfArray("answer.ns");
while ($i < $count_i) {
$json->put_I($i);
$name = $json->stringOf("answer.ns[i].name");
$ttl = $json->IntOf("answer.ns[i].ttl");
$domain = $json->stringOf("answer.ns[i].domain");
$i = $i + 1;
