It is common for address ranges to expand over time. A catch all network ensures that once that expansion occurs CA Application Delivery Analysis has calculations for it. If you see the client IP traffic show up in a broad default client network, use the QoS Users report to see the /24 client networks that are showing traffic and explicitly define those subset networks.
CA Application Delivery Analysis includes the following default entries for catch all default client networks:
Note: When client networks overlap, the management console reports the application traffic in the more specific client network.
Applications that face the Internet in the DMZ can be monitored with the All Others client network for subnet 0.0.0.0, mask 0 to monitor application activity for client networks that you have not explicitly defined. Do not use this client network to monitor other types of applications. If you do, the Operations and Engineering pages will show many unusual client IP addresses that are over threshold because they have no normal baseline.
Note: The All Others client network does not let you see TCP sessions, but does let the management console report application activity from other client networks.
