How to get a client's IP Address

I have a web app that need to get the client's IP Address. I have attempted several different methods without success. I have pasted the code below.

strDNS = Dns.GetHostName();

Session["UserIP"] = Dns.GetHostEntry(strDNS).AddressList[0].ToString();

I believe this will retreive the Server's IP address.

strDNS = HttpWorkerRequest.GetRemoteAddress.ToString();

I believe something along these lines should work but VS 2005 erros on build saying "Cannot convert method group 'GetRemoteAddress' to non-delegatetype 'object'.' How can I accomplish this task

That is great, I thing this gets the same infromation the code I posted gets. Doesn't the 'GetHostName' getting the server name and the IPAddress of the Server

Shouldn't I be using 'HttpWorkerRequest.GetRemoteAddress' to get the client IPAddress and How would I do that
Alias

strDNS = Dns.GetHostName();
Session["UserIP"] = Dns.GetHostEntry(strDNS).AddressList[0].ToString();

strDNS = HttpWorkerRequest.GetRemoteAddress().ToString();

Sorry, I have been out of the office. I have attempted to change the code but I continue to get the error on build "Error 1 An object reference is required for the nonstatic field, method, or property 'System.Web.HttpWorkerRequest.GetRemoteAddress()'"

WHat does this mean and How can i fix it

If it's a web app running from asp.net, wouldn't "Context.Request.UserHostAddress" get the IP of the client connecting to it Perhaps I'm misinterpreting what the question was

Sorry, posted the wrong code. Don't know what happend but here is the code i want to post:

IPAddress[] addresses = Dns.GetHostByName( "MACHINE1" ).AddressList;

foreach( IPAddress address in addresses )
{
Console.WriteLine( address.ToString() );
}

If the client has a private IP... the web server must be inside the client's network to retrieve the private IP. If you're not in the network, you'll only get the visible public IP of the router that's actually connecting to the server. The client would have to send it's internal IP in order for you to get it.

I believe you understand correctly, It is a web app that I am trying to get the User's IP Address. The IP returned from the code you provided returned, I Believe, the Router's IP Address. Is there an effective means to collect the user's IP
