Hi Mike,
I agree that using the one line answer will also filter the 2 other hosts - and get the answer wrong,..
well, is there any other good way to do the filter of such question systematically,
and not just grouping in all in one ( just like i did :( )
What I think now is
- the summarization net id should be started with one of the specified host - net id
eq - llike the 2 lines answer
- after the summarization again, breakdown again the member of
the summarization, to ensure that I only summarize what requested
thanks Mike

Your one line answer will also filter the following hosts:
49.1.0.1
49.1.0.9
If those hosts are not supposed to be filtered, then you will get the
problem wrong. The two line answer will only filter what is required.

Subject: Minimum amount of lines used -> to filter , Pls help TIA
Hi Guys,
I'm rather confused about this issue
- to filter the following hosts with the minimum amount of lines
49.3.0.1
49.5.0.1
49.7.0.1
49.3.0.9
49.5.0.9
49.7.0.9
At first, I come up with one line
49.1.0.1 wild-mask 0.6.0.8
for the second octet summarization
3 = 0 0 1 1
5 = 0 1 0 1
7 = 0 1 1 1
-----------------------
result = octet -> 1 with wild card 6
for the fourth octet summarization
1 = 0 0 0 1
9 = 1 0 0 1
---------------------
result = octet -> 1 with wild card 8
However , there's other opinion with 2 lines
49.3.0.1 wild-mask 0.0.0.8
49.5.0.1 wild-mask 0.2.0.8
which one is right - or there's any other best answer ?
TIA
