Creates, changes, or deletes CIDR blocks within a collection. Contains authoritative IP information mapping blocks to one or multiple locations.

A change request can update multiple locations in a collection at a time, which is helpful if you want to move one or more CIDR blocks from one location to another in one transaction, without downtime.

Limits

The max number of CIDR blocks included in the request is 1000. As a result, big updates require multiple API calls.

PUT and DELETE_IF_EXISTS

Use ChangeCidrCollection to perform the following actions:

• PUT: Create a CIDR block within the specified collection.

• DELETE_IF_EXISTS: Delete an existing CIDR block from the collection.
