CAB IP Ranges
To support internet access restrictions for customers CAB uses a well-defined set of DNS domains and addresses for both communication to CAB applications and services from customer networks and when CAB communicates with customer services.
CAB currently only supports IPv4 communications, IPv6 is not available.
