TcpListener TcpClient get IPAddress

Question

I wish to get the IPAddress from

Server side

TcpListener ftp_listener = new TcpListener(IPAddress.Any, ftpport);
 newclient = listener.AcceptTcpClient();

how do I find newclient ipaddress please

client side

TcpClient ftpclient = new TcpClient();
 ftpclient.Connect(ipAddress, ftpport);

how do I find ftpclient ipaddress

Currently I am using

 TcpClient ftpclient = new TcpClient();

            //get IpAddress of Server
#pragma warning disable CS0618 // Type or member is obsolete
            IPAddress ipAddress = Dns.Resolve("localhost").AddressList[0];
#pragma warning restore CS0618 // Type or member is obsolete

            ftpclient.Connect(ipAddress, ftpport);// "192.168.1.160", ftpport);

Is there a better way ...

Thanks

For both server and client, the approach for getting the remote endpoint (IP Address and Port) is the same.

1. Get the client IP Address on the server:

   IPEndPoint remoteIpEndPoint = newclient.Client.RemoteEndPoint as IPEndPoint;
   Console.WriteLine("Client IP Address is: {0}", remoteIpEndPoint.Address);
   

2. Get the server IP Address on the client:

       IPEndPoint remoteIpEndPoint = ftpclient.Client.RemoteEndPoint as IPEndPoint;
       Console.WriteLine("FTP Server IP Address is: {0}", remoteIpEndPoint.Address);
