====== IPAddressRule ======

Input validation rule that tests for a valid "dot-notation" IPv4 address.

===== Example =====

<code php>
$form->addRule (new IPAddressRule ('fieldName'));
</code>

This example checks that the value in the field "fieldName" is a valid IP address (for example: ''10.0.0.1'').
