=head1 NAME
Net::Packet::Target - an object for all network related stuff
=head1 SYNOPSIS
use Net::Packet::Target;
# Create multiple targets, with multiple port
my $t1 = Net::Packet::Target->new;
$t1->ip('www.google.com');
$t1->portRange('21,22,25,70-90');
$t1->protocol('tcp');
print $t1->isMultiple."\n";
for my $port ($t1->portList) {
print $t1->ip.' do stuff for port '.$port."\n";
}
# Create multiple targets, with only one port
my $t2 = Net::Packet::Target->new;
$t2->ipRange('127.0.0.1-10');
$t2->port(22);
$t2->protocol('tcp');
print $t2->isMultiple."\n";
for my $ip ($t2->ipList) {
print $t2->port.'/'.$t2->protocol.' do stuff for IPv4 '.$ip."\n";
}
# Create a single target
my $t3 = Net::Packet::Target->new;
$t3->ip('127.0.0.1');
$t3->port(22);
$t3->protocol('tcp');

=head1 DESCRIPTION
A B<Net::Packet::Target> object can be used to describe one target, or multiple targets. They are mainly used when you use some automated tasks you which to use on a range of IPs/ports.
To describe multiple targets, you simply enter an IP range, or a port range, or the two. To describe a single target, you enter one IP address, and one port. You can also avoid totally ports, or avoid totally IPs, you do what you want.
It also handles IP name resolution for IPv4 and IPv6, if available.
=head1 ATTRIBUTES
=over 4
=item B<mac> [ (scalar) ]
=item B<port> [ (scalar) ]
=item B<protocol> [ (scalar) ]
=item B<hostname> [ (scalar) ]
These 4 attributes store respectively the target mac address, port, protocol to use for port, and the hostname.
=item B<ipList> [ (arrayref) ]
=item B<portList> [ (arrayref) ]
These 3 attributes store respectively an IPv4 address list, an IPv6 address list, and a port list. All this as array references. When called without parameter, they return an array.

=head1 METHODS
=over 4
=item B<new>
Object constructor. There are no default values, due to the nature of this object.
=item B<isMultiple>
Because a B<Net::Packet::Target> object can be used to describe one target, or multiple ones, we must have a way to know that. This method is used to answer the question. Returns 1 if the object is composed of either multiple IPs, or multiple ports, 0 otherwise.
=item B<ip> [ (scalar) ]
Will take as a parameter an IPv4 address, or a hostname. Without argument, returns the stored value.
=item B<ip6> [ (scalar) ]
Same as previous, for IPv6.
=item B<ipRange> [ (scalar) ]
Will take as a parameter an IPv4 address range. The format is for example: 127.0.0.1-254, or 127.0-10.1.50-70. It will store the result in B<ipList> attribute, to be easily used in a B<for> loop.
=item B<portRange> [ (scalar) ]
Same as previous, but for port ranges. The format is for example: 1-1024, 500-600,100-110. It will store the result in B<portList> attribute, to be easily used ina B<for> loop.
