App::Manoc::IPAddress::IPv4 - IPv4 Addresses

=head1 VERSION

version 2.99.4

=head1 DESCRIPTION

A class for IPv4 addresses. Supports padding, unpadding,
stringification and comparison operators.

=head1 ATTRIBUTES

=head2 numeric

Address integer representation.

=head2 padded

=head2 unpadded

=head1 METHODS

=head2 address

Return the address in unpadded form. Automatically called by stringification.

=head2 TO_JSON

Convert to string

=head1 SYNOSPIS

  my $addr = App::Manoc::IPAddress::IPv4->new('10.1.100.1');


  $addr->padded; # '010.001.100.001'
  $addr->unpadded; # '10.1.100.1'

  "$addr" eq '10.1.100.1'; # true

  $addr > App::Manoc::IPAddress::IPv4->new('2.1.1.1'); # also true
