=head1 NAME

Data::Semantic::Net::IPAddress::IPv4 - Semantic data class for IPv4 addresses

=head1 VERSION

version 1.101760

=head1 SYNOPSIS

    my $obj = Data::Semantic::Net::IPAddress::IPv4->new;
    if ($obj->is_valid('...')) {
        # ...
    }

=head1 DESCRIPTION

This class can tell whether a value is an IPv4 address. The C<valid()> method
will respect the inherited C<forbid_internal> boolean attribute.

=head1 METHODS

=head2 is_internal

Takes a value and returns true if the indicated IPv4 address is an internal
address, for example, C<10.0.1.1>, C<127.0.0.1> or C<192.168.1.3>.

=head2 is_valid_normalized_value
