    Default How to block a IP range in CSF?

    Hi, what do i put into deny.csf to block these IP ranges? Subnets are so hard to understand!

    31.23.86.*
    65.21.*.*
    87.*.*.*

    Thanks!

    Try using an IP to CIDR calculator:

    IP to CIDR online converter

    For instance the 87 block would be 87.0.0.0/32
