Allow CIDR notation in our IP filter implementation
Description
We have the possibility to allow filtering in various places for IPv4 and IPv6 addresses. To have more complex filter possibilities we have an own syntax, e.g. 192.168.1.0-255. For administrators, it is a common way to describe networks in CIDR notation like 192.168.1.0/24 from /0 until /32 for the number of bits in the subnet mask. This would be the same for IPv6 with /0 to /128.
