NetFlow report - IP range

Hi all!

I am trying to create a report of data usage on a specific subset of IP-s.

I use dynamic query builder (DQB), to get the data.

It is working fine and I get all the data I need,

But now I would like to filter out IP-s, that are not important to me.

I searched for the solution and came across many posts stating that DQB supports regex.

So I tried that, but without success. Am I doing something wrong?

Thanks for any advice.

Regards, Srečko.
