I have this range of IPS 197.192.x.x that is brute force attacking my pop/imap/smtp servers day after day. I have this ipset in place that is blocking every IP that tries to hack on my server. I would like to block access for pop/smtp/imap for all IPs starting with 197.192 To do this, I have typed this command: ipset -A myIpset 197.192.0.0/24 but this added 65536 IPs to my ipset, making it huge and now I cannot add more IPs to it. Is there another way to do this in a more elegant way?
