Thanks jwkrahn, I really appreciate the corrections! I have included them in the script and read the section on error variables in perlvar.

Also, my first version used Moose (influenced by the book "Modern Perl"). After looking at the script, and comparing it with the bash scripts, it took more time and resources. I guess that Moose is for larger and more complex projects, so I have rewritten in what I assume is "procedural programming". It has been trivial to have Moose out, transforming the package into a subroutine.

One thing is puzzeling me is the regex. In a file in this format:

Start   End     Netblock        Attacks Name    Country email
116.45.99.0     116.45.99.255   24      1799                    
46.21.150.0     46.21.150.255   24      1708                    
121.243.146.0   121.243.146.255 24      1446

Applying this regex:

 qr/^(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/m

Gives me:

116.45.99.0
46.21.150.0
121.243.146.0

And this regex:

qr/^((\d{1,3}\.){3}\d{1,3})/m

Gimes me:

116.45.99.0
99.
46.21.150.0
150.
121.243.146.0
146.

I would expect the same result.
