<p>
Disassociates a CIDR block from a VPC. To disassociate the CIDR block, you must specify its association ID. You
can get the association ID by using <a>DescribeVpcs</a>. You must detach or delete all gateways and resources
that are associated with the CIDR block before you can disassociate it.
</p>
<p>
You cannot disassociate the CIDR block with which you originally created the VPC (the primary CIDR block).
