I needed a quick way to find my IP without using Telnet so I added http://mcgrane.uk/ip to my site. Here’s the ASP Classic  code because I was feeling nostalgic.

<%@Language="VBScript"%>
<%
If Request.QueryString("debug") = "1" Then
  Response.Write("<pre>")
  For Each x in Request.ServerVariables
    Response.Write(X & " = " & Request.ServerVariables(X) & vbCrLf)
  Next
  Response.Write("</pre>")
Else
  If Len(Request.ServerVariables("HTTP_X_FORWARDED_FOR")) = 0 Then
    Response.Write Request.ServerVariables("REMOTE_ADDR")
  Else
    Response.Write Request.ServerVariables("HTTP_X_FORWARDED_FOR")
  End If
End If
%>
