(Unicode C++) 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.
#include <CkDnsW.h>
#include <CkJsonObjectW.h>
void ChilkatSample(void)
{
CkDnsW dns;
CkJsonObjectW json;
json.put_EmitCompact(false);
bool success = dns.Query(L"NS",L"x.com",json);
if (success == false) {
wprintf(L"%s\n",dns.lastErrorText());
return;
}
wprintf(L"%s\n",json.emit());
// Sample response.
// Parsing code below..
// {
// "answer": {
// "ns": [
// {
// "name": "x.com",
// "ttl": 86400,
// "domain": "alexia.ns.cloudflare.com"
// },
// {
// "name": "x.com",
// "ttl": 86400,
// "domain": "tosana.ns.cloudflare.com"
// }
// ]
// }
