ec2-disassociate-address

Description

Disassociates an Elastic IP address from the instance or network interface it's assigned to.

This action applies to both EC2 Elastic IP addresses and VPC Elastic IP addresses. For information about VPC addresses and how they differ from EC2 addresses, go to Elastic IP Addresses in the Amazon Virtual Private Cloud User Guide.

This is an idempotent action. If you enter it more than once, Amazon EC2 does not return an error.

The short version of this command is ec2disaddr.
