Dears, By default, PRTG monitor and display all data pass an interface. But I want to display traffic of certain ranges IP ( such as: traffic of only ranges 210.211.0.0/16, 115.110.0.0/16). Can PRTG do that? Thank you very much

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].

Ranges are made like this: IP[115.110.2-14.1-42]

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 :)

I will try to test and see it. Many thanks for your help!

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