VB.NET Pogramming question(how to get the ip)

Just wondering if there is a easier way to get the ip through vb.net code then having the client when he logs in send a text message of what his ip he is using. Here is my code

While (bExit = False)

'accept an incoming connection
connection = listener.AcceptTcpClient

'Get Data
socketStream = connection.GetStream

'declare a byte array to store data
Dim bytes(connection.ReceiveBufferSize) As Byte

'Transfer Data from Stream to byte array
socketStream.Read(bytes, 0, CInt(connection.ReceiveBufferSize))

'Conver the Byte into String
reader = Encoding.ASCII.GetString(bytes)

'Indicate that Data was received successfully on the Form
Me.txtData.Text &= vbCrLf & "Connection received."

' Step 4: Display the message on the form
Me.txtData.Text &= vbCrLf & "Message: " & reader

'Show as a marker of end of message
Me.txtData.Text &= vbCrLf & "User terminated connection" & vbCrLf

'Close connection
socketStream.Close()
connection.Close()

End While

What i'm wanting to do is every time a person connects it stores there ip in a array or in later projects a database. If I store it in the array I can store what clients are connected then when client 1 sends a message, the server sends it out to all the rest of the clients pretty much like a messaging program. Late r projects I also want to store there user name to see who does what but you get my idea I think. If you have any questions let me know.

What is 'connection' defined as?

Here is the top chunk of my code

Imports System.Net.Sockets
Imports System.Threading
Imports System.Text

Public Class TCPServerForm
Inherits System.Windows.Forms.Form

Private connection As TcpClient ' Socket object handles connection
Private readThread As Thread ' server thread

'Stream through which to transfer data
Private socketStream As NetworkStream

'Objects for writing and reading data
Private reader As String
Dim listener As TcpListener

'Boolean item to communicate with thread
Dim bExit As Boolean = False

Where is the "connection" made to the server?

From a client app , i will post the code that makes the connection.
But just too be sure im wondering if there is a way I dont have to send the ip lets say in text to the serve just a built in function like connection.getip obviously that dont exist but you get the point.

Private Sub btnSend_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnSend.Click

Dim tcpClient As New System.Net.Sockets.TcpClient 'TCP Client Socket
Dim StreamData As NetworkStream 'Declaration to Send data as a stream

'Connect the TCP Client to ServerIP and Port
tcpClient.Connect(Me.txtIP.Text, CInt(Me.txtport.Text))

I don't think that information is available anywhere, but that doesn't mean that it is not possible, it just means that it wasn't where I thought it would be.

I mean somehow the server has to know the clients ip address if its requesting a connection. Especially if its going to talk back.

You know what I just found that as well, was just reading it actually. haha

I tried everything I could find but tcpclient i figured it would be in the connection peice. Well thank you so very much on going thru this and helping me out!
