Get user accessing ip address in rails?

Get user accessing ip address rails?

request.ip ->returns the ip, whether is is a local proxy ip (localhost address) or not.
*request.remote_ip -> is smarter and gets the ip address of the client outside of local proxies.
3)If you are using apache in front of a mongrel, then remote_ip will return the source address of the request, which in this case will be local host because the Apache web server is making the request, so instead put this in your controller:

@remote_ip = request.env["HTTP_X_FORWARDED_FOR"]
