Given that you already tagged the question with netflow-v9, I assume that you already use the corresponding sensors. You can surely reduce the monitored IP range. To do so, please enter the following include filter configuration in the sensor settings of a new netflow sensor:

IP[210.211.0.0/16] OR
IP[115.110.0.0/16]

You can also create two new netflow sensors and use it for each IP area :)

Dear Stephan, Does PRTG limit the number of IP range on the Include/exclude filter? Can I add 500 ranges of IP on it ( Such as: IP [Ip range 1] or IP [IP range 2] or............................... or IP [IP range 500].

No, no, I want to monitor International traffic ( of my country: Vietnam), so that I have to enter all of our country IP range in the exclude filter. Vietnam have about 500 IP ranges ( such as: 49.213.64.0/18; 203.99.248.0/22; 202.172.4.0/23; 203.170.26.0/23; 103.7.36.0/22; 45.126.96.0/22; 202.87.212.0/22........), so I have to add all of them. But I wonder if PRTG limit the maximum of IP range?

Not that we're aware of - just test it and see if it works :)

Alright :) Let me know if you hit any limitations - I'm not sure if it has been tested with that many networks :)
