field ip_address => {
    required        => 1,
    check_blacklist => 1
};

1;

... in your application:

package main;

use MyApp::Person;

my $person = MyApp::Person->new(ip_address => '0.0.0.0');

unless ($person->validates('ip_address')) {
    # handle validation error
}

DESCRIPTION

You can extend Validation::Class by creating your own validation rules (directives). Validation::Class::Directive provides a base-class for you to use when creating new directive classes. Please see Validation::Class::Directives for a complete list of core directives.
