How to log Client IP Address and Machine Name in ASP.NET

Question

I am developing a Web Application in ASP.net, which requires login name and password.

I want to log IP Address and Machine Name of client, who are accessing this Web Application.

I am using log4net for logging.

I have tried this piece of code, but I am getting Server Machine HostName in log after deploying this web application using IIS-7 instead of Client Machine Name.

Login Page Page_Load Method:

protected void Page_Load(object sender, EventArgs e) { log4net.GlobalContext.Properties["Hostname"] = Dns.GetHostName(); }

Web.Config Changes:

 <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date %property{Hostname} [%thread] %-5level %logger - %message%newline" /> </layout>

Its really huge project, So Please suggest me the way which requires minimum changes in Code to log the IP Address and Machine Name of Client.

Did you try using following?

Request.UserHostAddress Request.UserHostName

Refer to following answer posted on a different thread

Try For Client Computer name..

string[] computer_name = System.Net.Dns.GetHostEntry(Request.ServerVariables["remote_addr"]).HostName.Split(new Char[] { '.' }); String ecname = System.Environment.MachineName; txtComputerName.Text = computer_name[0].ToString();

For Client IP address..

Request.ServerVariables["REMOTE_ADDR"]

Dns.GetHostEntry(log.IPAddress).HostName

For some reason the other answers didn't work on my shared hosting server. Go figure...

For Client IP:

System.Web.HttpContext.Current.Request.ServerVariables["**REMOTE_ADDR**"];

For Client Hostname:

System.Net.Dns.GetHostEntry(Request.ServerVariables["**REMOTE_HOST**"]).HostName;

Ensure that the server on which this application is hosted must have correct entry for the DNS Servers in TCP/IP configuration.
