Disable IP address logging Rails

Question

I am trying to disable logging of IP addresses while handling the request. But I am not able find a way to do this. I want to disable logging of IP for limited portion of my app where user is not yet authenticated.

So my questions is

How to disable logging of IP in rails log for specific pages(so the IP will not be saved in any log)

I am using Rails 3.2.17

EDIT: Here is sample log (from environment.log)

Started GET "/my_path" for 192.168.0.109 at 2014-03-28 11:53:20 +0530

I do not want to save 192.168.0.109 in log file

In config/initializers, add file log_fomat.rb with:

class ActiveSupport::BufferedLogger
  def formatter=(formatter)
    @log.formatter = formatter
  end
end

class Formatter
  SEVERITY_TO_TAG_MAP     = {'DEBUG'=>'meh', 'INFO'=>'fyi', 'WARN'=>'hmm', 'ERROR'=>'wtf', 'FATAL'=>'omg', 'UNKNOWN'=>'???'}
  SEVERITY_TO_COLOR_MAP   = {'DEBUG'=>'0;37', 'INFO'=>'32', 'WARN'=>'33', 'ERROR'=>'31', 'FATAL'=>'31', 'UNKNOWN'=>'37'}
  USE_HUMOROUS_SEVERITIES = true

  def call(severity, time, progname, msg)
    if USE_HUMOROUS_SEVERITIES
      formatted_severity = sprintf("%-3s","#{SEVERITY_TO_TAG_MAP[severity]}")
    else
      formatted_severity = sprintf("%-5s","#{severity}")
    end

    formatted_time = time.strftime("%Y-%m-%d %H:%M:%S.") << time.usec.to_s[0..2].rjust(3)
    color = SEVERITY_TO_COLOR_MAP[severity]

    "\033[0;37m#{formatted_time}\033[0m [\033[#{color}m#{formatted_severity}\033[0m] #{msg.strip} (pid:#{$$})\n"
  end

end

Rails.logger.formatter = Formatter.new
