Obtaining a Connecting Client's IP Address

What I would like to know is how I can go about obtaining the IP of a client connecting to my server while trying to login. The reason for this is because I would like my server to compare the IP with acceptable IPs in an XML file.

Now I know one solution would be to make my own packets and have the client send his/her IP somewhere in a login packet, put implementing packets takes quite a lot of time and this is only a small project, experiment, w/e.

Any help will be greatly appreciated. :)

It really depends what you are using for connection.
is it sockets? ordinary HTTP? what are you using for client to connect?

I am using source based off of the example found here:

http://www.codeguru.com/Csharp/Cshar...cle.php/c7695/

My client connects using this function:

void Join(object sender, System.EventArgs e)
{
if(port.Text == "" || IP.Text == "")
{
MessageBox.Show("IP Address and Port Number are required to connect to the Server\n");
return;
}

try
{
m_clientSocket = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
IPAddress ip = IPAddress.Parse (IP.Text);
int iPortNo = System.Convert.ToInt16 ( port.Text);
IPEndPoint ipEnd = new IPEndPoint (ip,iPortNo);
m_clientSocket.Connect ( ipEnd );

if(m_clientSocket.Connected)
{
WaitForData();
}
}
catch(SocketException se)
{
string str = "\nConnection failed, is the server running?\n" + se.Message;
MessageBox.Show (str);
}
}

get address list from Ipendpoint.

care to elaborate on that? :)

I'm still new to C# sockets...

in your server...

Socket m_ConnectedClientSocketHandler = /*Client connection*/

Console.WriteLine(IPAddress.Parse (((IPEndPoint)ConnectedClientSocketHandler .RemoteEndPoint).Address.ToString ()));

try either of this

x=Request.ServerVariables["REMOTE_ADDR"]

or

x=Request.ServerVariables["REMOTE_HOST"]

suhaib, that would work perfect for a web request. but here, as i understand, he is working using Sockets and need to get the IP address of the connecting client.

thanks for you suggestion. it is nice, now I will know too :)
