Hi All,

I have to fetch the ip address client machine.
for this i use the below code:

C#

protected void Application_BeginRequest(object sender, EventArgs e)
   {
       HttpRequest request = base.Request;
       string address = request.UserHostAddress;
       base.Response.Write(address);
   }

My Ip Address is 202.164.45.14
But when i run the above code on my local system, it returns ::1
And when i deploy it on my internal server it is giving 192.168.3.1

I also tried

HttpRequest.ServerVariables["REMOTE_ADDR"]

but it also gave same result.

Thanks,
Richa Sharma

::1 is your address. Just as 127.0.0.1 is the loopback address in IPv4, ::1 is the loopback on IPv6
see Localhost[^]
Unless you need a "properly" resolved IP I'd keep your code, once it had been tested from another machine on the network.

HttpContext context = ((HttpApplication)sender).Context;
string currentIP = context.Request.UserHostAddress;
if (!IsIpValid(currentIP))
{
context.Response.StatusCode = 403;
}

Thanks all for your interest in this question.
But the problem is firewalls. When i deploy this on server, it is working fine.

Thanks,
