Hi,

I just tried to gather some information for DDoS incident here
with nfsen and was interested what came form the classical
Class-B range (128/8 - 191/8).

So I tried the filter 128.0.0.0/2 which did not give the expected
result.

I found out, that 128.0.0.0/5 worked as expected, but not 136.0.0.0/5
and also not 128.0.0.0/4.

Do I do something wrong or is it a feature (aka bug)?

Best regards, Jens Hektor
