@addr = $ec2->describe_addresses(@public_ips)¶

@addr = $ec2->describe_addresses(-public_ip=>\@addr,-allocation_id=>\@id,-filter->\%filters)¶

Queries AWS for a list of elastic IP addresses already allocated to you. All arguments are optional:

 -public_ip     -- An IP address (in dotted format) or an arrayref of
                   addresses to return information about.
 -allocation_id -- An allocation ID or arrayref of such IDs. Only 
                   applicable to VPC addresses.
 -filter        -- A hashref of tag=>value pairs to filter the response
                   on.

The list of applicable filters can be found at http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeAddresses.html.

This method returns a list of VM::EC2::ElasticAddress.

$address_info = $ec2->allocate_address([-vpc=>1])¶

Request an elastic IP address. Pass -vpc=>1 to allocate a VPC elastic address. The return object is a VM::EC2::ElasticAddress.

$boolean = $ec2->release_address($addr)¶

Release an elastic IP address. For non-VPC addresses, you may provide either an IP address string, or a VM::EC2::ElasticAddress. For VPC addresses, you must obtain a VM::EC2::ElasticAddress first (e.g. with describe_addresses) and then pass that to the method.

$result = $ec2->associate_address($elastic_addr => $instance_id)¶

Associate an elastic address with an instance id. Both arguments are mandatory. If you are associating a VPC elastic IP address with the instance, the result code will indicate the associationId. Otherwise it will be a simple perl truth value ("1") if successful, undef if false.

If this is an ordinary EC2 Elastic IP address, the first argument may either be an ordinary string (xx.xx.xx.xx format) or a VM::EC2::ElasticAddress object. However, if it is a VPC elastic IP address, then the argument must be a VM::EC2::ElasticAddress as returned by describe_addresses(). The reason for this is that the allocationId must be retrieved from the object in order to use in the call.

$bool = $ec2->disassociate_address($elastic_addr)¶

Disassociate an elastic address from whatever instance it is currently associated with, if any. The result will be true if disassociation was successful.

If this is an ordinary EC2 Elastic IP address, the argument may either be an ordinary string (xx.xx.xx.xx format) or a VM::EC2::ElasticAddress object. However, if it is a VPC elastic IP address, then the argument must be a VM::EC2::ElasticAddress as returned by describe_addresses(). The reason for this is that the allocationId must be retrieved from the object in order to use in the call.
