Looking up Whois Info the Right Way - mrkoolaid - Oct 22, 2016

You can find a nice Whois Server list on Github

Add Using statement:

Code 
using System.Net;

using System.Net.Sockets;

Global Declarations:

Code 
public string whois_server;

public int whois_port;

public TcpClient client;

public string dns_qry;

Form Load Event:

Code 
whois_port = 43;

whois_server = textBox1.Text;

dns_qry = string.Empty;

Tetxbox 2 Keypress Event:

Code 
switch ((Keys)e.KeyChar)

{

    case Keys.Enter:

        client = new TcpClient();

        textBox3.Text = "";

        client.Connect(whois_server, whois_port);

        dns_qry = textBox2.Text + "\r\n";

        byte[] qry_bytes = Encoding.ASCII.GetBytes(dns_qry.ToCharArray());

        Stream dns_strm = client.GetStream();

        dns_strm.Write(qry_bytes, 0, qry_bytes.Length);

        StreamReader rdr = new StreamReader(dns_strm, Encoding.ASCII);

        while (rdr.ReadLine() != null)

        {

            textBox3.Text += rdr.ReadLine() + Environment.NewLine;

        }

        rdr.Close();

        dns_strm.Close();

        client.Close();

        break;

}

I think you are skipping half of the lines.
