HFS: IP masks
Computers in every network (e.g.,Internet, LAN,...) are identified by IP addresses (shortened to IP).
For some input in HFS you have to specify one or more IP (e.g. banning).
This article describes the syntax you can use to specify such IPs.
Just type the IP you want:
All but one
To exclude an IP, put a backslash \ before it:
Ranges can be specified by putting a dash - between first and last IP
192.168.0.20 and 192.168.0.50 are included.
You can use wildcards as well (? for single character, * for any number of characters)
Using semicolon ; you can specify more than one address
You can combine any of the above methods in the same IP mask
