CIDR Notation
WeConfig frequently makes use of so called CIDR notation, which is a way of writing an IP address coupled with a netmask in the format IP/BitCount, where IP is the full IP address (either IPv4 or IPv6) and BitCount is the number of bits from the start of the netmask that are 1.
Examples
