How to get client IP and Server IP using Rails

Question

Can anyone please help how to get client IP and also server IP using Ruby on Rails?

Answer 1

From your controller:

request.remote_ip 

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"] 

To get the server IP see:

Thanks: karim79 and Titanous.

Write the code in Controller

For Client IP:

request.remote_ip  @remote_ip = request.env["HTTP_X_FORWARDED_FOR"] 

For Server IP:

require 'socket'  def local_ip   orig, Socket.do_not_reverse_lookup = Socket.do_not_reverse_lookup, true  # turn off reverse DNS resolution temporarily    UDPSocket.open do |s|     s.connect '64.233.187.99', 1     s.addr.last   end ensure   Socket.do_not_reverse_lookup = orig end
