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

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"))%>

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