How to get IP of Heroku server, where is placed my app?

I am trying to get IP address of server, where is running my app. In PHP exists the function called GetHostByName() (or something like that), what is the alternative for Ruby?

You can use this (no shell required):

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

Output:

# irb:0> local_ip
# => "192.168.0.1"

I use this function, but credit goes to: http://coderrr.wordpress.com/2008/05/28/get-your-local-ip-address/
