(.NET Core 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.
Chilkat.Dns dns = new Chilkat.Dns();
Chilkat.JsonObject json = new Chilkat.JsonObject();
json.EmitCompact = false;
bool success = dns.Query("AAAA","x.com",json);
if (success == false) {
Debug.WriteLine(dns.LastErrorText);
return;
}
Debug.WriteLine(json.Emit());
// 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"
// }
// ]
// }
// }

string name;
int ttl;
string ipv6;
int i = 0;
int count_i = json.SizeOfArray("answer.aaaa");
while (i < count_i) {
json.I = i;
name = json.StringOf("answer.aaaa[i].name");
ttl = json.IntOf("answer.aaaa[i].ttl");
ipv6 = json.StringOf("answer.aaaa[i].ipv6");
i = i + 1;
}
