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

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

Swift

func chilkatTest() {
    var success: Bool = false

    let dns = CkoDns()!

    let json = CkoJsonObject()!
    json.emitCompact = false

    success = dns.query(recordType: "AAAA", domain: "x.com", answer: json)
    if success == false {
        print("\(dns.lastErrorText!)")
        return
    }

    print("\(json.emit()!)")

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

    // {
    //   "answer": {
    //     "aaaa": [
    //       {
    //         "name": "x.com",
    //         "ttl": 229,
    //         "ipv6": "2606:4700:4400::ac40:96f2"
    //       },
