I have this IP list shown below. How i can calculate all ip addresses from that in Linux? Is there some tools that can calculate that for me ? I need that to check if i have not banned some cloudflare IP's. As firewall i am using shorewall and i am banning with fail2ban single IP. As i know, then i cannot detect subent mask from IP adress, right?
