I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.

Module have a bug.
For example: ip = 193.152.96.104, mask = 21.

Result:
Invalid prefix 11000001100110000110000001101000/21 at test.pl line 46.


Correct interpretation:
Address: 193.152.96.104 11000001.10011000.01100 000.01101000
Netmask: 255.255.248.0 = 21 11111111.11111111.11111 000.00000000
