Adding CIDR addresses to IP blocking list?

Hello,

Can I use CIDR IP ranges or normal IP ranges in the IP address blocking list or is that for single IP addresses?

i.e. - (CIDR) 192.168.0.0/24 or (IP range) 192.168.0.0-192.168.0.255 instead of blocking several ip addresses in that range like 192.168.0.5,192.168.0.26,192.168.0.127

Thanks,

Kim
