(C++) DNS Query AAAA Records
Shows how to perform a DNS query to retrieve AAAA records.
Note: This example requires Chilkat v9.5.0.96 or later.
#include <CkDns.h>
#include <CkJsonObject.h>
void ChilkatSample(void)
{
CkDns dns;
CkJsonObject json;
json.put_EmitCompact(false);
bool success = dns.Query("AAAA","x.com",json);
if (success == false) {
std::cout << dns.lastErrorText() << "\r\n";
return;
}
std::cout << json.emit() << "\r\n";
// Sample response.
// Parsing code below..
// {
// "answer": {
// "aaaa": [
// {
// "name": "x.com",
// "ttl": 229,
// "ipv6": "2606:4700:4400::ac40:96f2"
// },
// {
// "name": "x.com",
// "ttl": 229,
// "ipv6": "2606:4700:4400::6812:250e"
// }
// ]
// }
// }
