DNS Query SOA Records

See more DNS Examples

Shows how to perform a DNS query to retrieve SOA records.

Note: This example requires Chilkat v9.5.0.96 or later.

Rust

let dns = chilkat::Dns::new();

let json = chilkat::JsonObject::new();
json.set_emit_compact(false);

if dns.query("SOA", "x.com", &json).is_err() {
    println!("{}", dns.last_error_text());
    return;
}

println!("{}", json.emit().unwrap_or_default());

// Sample response.
// Parsing code below..

// {
//   "answer": {
//     "soa": [
//       {
//         "name": "x.com",
//         "ttl": 1800,
//         "mname": "alexia.ns.cloudflare.com",

//     ]
