How to get the socket information(such as source ip address and target ip address) from HttpResponseMessage or related exception?

If it is not currently supported, can it be provided in the next version?

e.g:

        [HttpGet]
        public string Get()
        {

            var feature = Request.HttpContext.Features.Get<IHttpConnectionFeature>();
            //return feature.LocalIpAddress.ToString();
            return feature.RemoteIpAddress.ToString();

        }

Good luck.

Is http client request, not asp.net/asp.net core.

Can you explain why you care about this information?

edit: To answer the original question, there's no way to get this info from HttpResponseMessage currently.

We could consider adding this in the future, but to do so we need to understand the motivation for it.

.Net 6

using System.Net.Sockets;

SocketsHttpHandler handler = new SocketsHttpHandler();
handler.ConnectCallback = async (context, cancellationToken) =>
{
    Socket socket = new Socket(SocketType.Stream, ProtocolType.Tcp);
    socket.NoDelay = true;

    try
    {
        await socket.ConnectAsync(context.DnsEndPoint, cancellationToken).ConfigureAwait(false);
        Console.WriteLine(context.DnsEndPoint);
        Console.WriteLine(socket.RemoteEndPoint.ToString()); //IP Address 
        return new NetworkStream(socket, true);
    }
    catch
    {
        socket.Dispose();
        throw;
    }
};
using (var httpClient = new HttpClient(handler))
{
    var result = await httpClient.GetAsync("https://www.google.com");
}

audit logs was big one I have seen in the past @geoffkizer. Either for regulatory reasons or for troubleshooting.
