=head1 NAME VM::EC2::REST::private_ip

=head1 SYNOPSIS

 use VM::EC2 ':vpc';

=head1 METHODS

These methods allow you to control private IP addresses associated
with instances running in a VPC.

=head2 $result = $ec2->assign_private_ip_addresses(%args)

Assign one or more secondary private IP addresses to a network
interface. You can either set the addresses explicitly, or provide a
count of secondary addresses, and let Amazon select them for you.

Required arguments:

 -network_interface_id    The network interface to which the IP address(es)
                          will be assigned.

 -private_ip_address      One or more secondary IP addresses, as a scalar string
 -private_ip_addresses    or array reference. (The two arguments are equivalent).

Optional arguments:

 -allow_reassignment      If true, allow assignment of an IP address is already in
                          use by another network interface or instance.

The following are valid arguments to -private_ip_address:

 -private_ip_address => '192.168.0.12'                    # single address
 -private_ip_address => ['192.168.0.12','192.168.0.13]    # multiple addresses
 -private_ip_address => 3                                 # autoselect three addresses

The mixed form of address, such as ['192.168.0.12','auto'] is not allowed in this call.

On success, this method returns true.

    $self->call('AssignPrivateIpAddresses',@parms);
}

=head2 $result = $ec2->unassign_private_ip_addresses(%args)

Unassign one or more secondary private IP addresses from a network
interface.

Required arguments:

 -network_interface_id    The network interface to which the IP address(es)
                          will be assigned.

 -private_ip_address      One or more secondary IP addresses, as a scalar string
 -private_ip_addresses    or array reference. (The two arguments are equivalent).


The following are valid arguments to -private_ip_address:

 -private_ip_address => '192.168.0.12'                    # single address
 -private_ip_address => ['192.168.0.12','192.168.0.13]    # multiple addresses

On success, this method returns true.
