How to get the IP Address of a Remote Socket Endpoint

Here is how we can IP address, you need to use below namespace library

using System.Net.Sockets;

IPHostEntry ipHostInfo1 = Dns.GetHostEntry(Dns.GetHostName());
// loop through list of system IP address 
// get the IP4 Address of the current machine
foreach (IPAddress ipaddr in ipHostInfo1.AddressList)
{
    if (ipaddr.ToString() == ConfigurationManager.AppSettings["SystemIPAddress"].ToString())
    {
        strIpAddress = ipaddr.ToString();
        break;
    }

}

                
IPAddress ipAddress = IPAddress.Parse(strIpAddress);

Hope this helps!
