This code helps you store IP addresses as ints in the database.

Create a column on your ActiveRecord model to store IP addresses.

  script/generate add_ip_column MyModel
  rake db:migrate

Then in your model, use has_ip_column...

  class MyModel < ActiveRecord::Base    
    has_ip_column :ipaddress
    ...
  end

On instances of MyModel, you can now set ipaddress as a dotted decimal string:

  MyModel.new(:ipaddress => "201.102.201.102")

When you save the model, it's stored as an integer in the database.
