title: Is there a solid way to get a user's IP, despite them being behind a proxy or similar?

  <p>Is there a solid way to get a user's IP address despite them being behind a proxy, tor, etc?
  Preferably using ASP.NET</p>
  
  <p>I just cannot imagine "big sites" like Google, Hotmail/Outlook not having some relatively reliable way of bypassing these things, especially since they (atleast hotmail/outlook) require you to use Javascript.</p>
