DNS Query NS Records

See more DNS Examples

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

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

Go

    success := false

    dns := chilkat.NewDns()

    json := chilkat.NewJsonObject()
    json.SetEmitCompact(false)

    success = dns.Query("NS","x.com",json)
    if success == false {
        fmt.Println(dns.LastErrorText())
        dns.DisposeDns()
        json.DisposeJsonObject()
        return
    }

    fmt.Println(*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"
    //       }
    //     ]
    //   }
    // }

    var name *string = new(string)
    var ttl int
    var domain *string = new(string)

    i := 0
    count_i := json.SizeOfArray("answer.ns")
    for i < count_i {
        json.SetI(i)
        name = json.StringOf("answer.ns[i].name")
        ttl = json.IntOf("answer.ns[i].ttl")
        domain = json.StringOf("answer.ns[i].domain")
        i = i + 1
    }


    dns.DisposeDns()
    json.DisposeJsonObject()
