Address lists downloader (DShield, Spamhaus DROP/EDROP, etc)

How does it handle 1.2.3.0/24 addresses and as far I could it enters 1.2.3.0 in the addresslist without the /24?

Update: I ran the script and it does handles the range (cidr) correctly. Going to look if I can add some more lists.

Update 2: excellent script and I have added the option to filter on a specific label in file and that also can be used to remove a list that is not used anymore, from the current blacklist in the addresslist.
