Get real IP address in local Rails development environment

I have Rails 2.3.8, Ruby 1.8.7, Mongrel Web Server and MySQL database.

I am in the development mode and I need to find the real IP address

When I use request.remote_ip I am getting the IP as 127.0.0.1

I know I am getting 127.0.0.1 because I am developing on the local machine.. but is there a way to get the real ip-address even if I am on the local machine?

I am using these mentioned below in my controller and all I get is 127.0.0.1 with all of them in the view.

request.remote_ip
request.env["HTTP_X_FORWARDED_FOR"]
request.remote_addr
request.env['REMOTE_ADDR']

As far as I can see there is no standard method for getting the remote address of your local machine. If you need the remote address for (testing) your geocoding, I suggest adding 127.0.0.1 to your database table that matches IP addresses with locations.

As a last resort you could also hard code your remote address. E.g. like this:

class ApplicationController < ActionController::Base
  def remote_ip
    if request.remote_ip == '127.0.0.1'
      # Hard coded remote address
      '123.45.67.89'
    else
      request.remote_ip
    end
  end
end

class MyController < ApplicationController
  def index
    @client_ip = remote_ip()
  end
end

This is what I normally do nowadays:

if Rails.env.production?
  request.remote_ip
else
  Net::HTTP.get(URI.parse('http://checkip.amazonaws.com/')).squish
end
