This example demonstrates how to find out the visitor's browser type, IP address, and more:

<html>
<body>

You are browsing this site with:
<%Response.Write(Request.ServerVariables("http_user_agent"))%>


Your IP address is:
<%Response.Write(Request.ServerVariables("remote_addr"))%>


The DNS lookup of the IP address is:
<%Response.Write(Request.ServerVariables("remote_host"))%>


The method used to call the page:
<%Response.Write(Request.ServerVariables("request_method"))%>


The server's domain name:
<%Response.Write(Request.ServerVariables("server_name"))%>


The server's port:
<%Response.Write(Request.ServerVariables("server_port"))%>

Getting Geographic Location(country) of internet user ASP.NET C#

Here is a FREE web service that will give you Country information from IP address.
http://www.webservicex.net/WS/WSDetails.aspx?WSID=64&CATID=12

But if you want to pay and get more featured service, then you may check here
http://www.ip2country.net/ip2country/lookup.html
This website does not sell Web Service, rather they sell lookup DataBase. You will need to purchase a database from them and then use your ASP.NET look up query to get county information.

Getting Client IP address using ASP.NET C#

You can use the following three ways to get the client IP address using C#

string test = Request.UserHostAddress.ToString();
string test2 = Request.ServerVariables["REMOTE_ADDR"].ToString();
string test3 = Context.Request.UserHostAddress.ToString();

All are returning the same values...

Some times client can mask their IP behind a router/nat and it's spoofable.
