Remote user IP Address

[Henrique Ordine]

Hello everyone,

I'm using request.getRemoteAddr() in my servlet and it returns "127.0.0.1" to me, not the actual IP address. I need tha actual IP address. I'm accessing the Servlet from the same machine where the J2EE server is running. Could anyone please tell me what the problem is?

What does it return if you access the server from some other machine?

If you access it via http://localhost you get the loop back IP, if you use the machine name ie http://machinename then you get the machine IP

That was useful to me as well

Thanks David, you're right!
Ulf, from another machine, it returned the machine's ip address.

This trick is handy when testing IP-specific code. We had specific code for Kiosks running on fixed addresses. If you register one IP in your app then you can send requets and test the code works correctly.
