  A form to create an IP address that will be blocked or whitelisted.
  Example usage:

    {{screened-ip-address-form action=(action "recordAdded")}}

  where action is a callback on the controller or route that will get called after
  the new record is successfully saved. It is called with the new ScreenedIpAddress record
  as an argument.
