 Subnets can either be single MAC, IPv4 or IPv6 addresses,
 in which case a subnet consisting of only that single address is assumed,
 or they can be a IPv4 or IPv6 network address with a prefixlength.
-Shorthand notations are not supported.
 For example, IPv4 subnets must be in a form like 192.168.1.0/24,
 where 192.168.1.0 is the network address and 24 is the number of bits set in the netmask.
 Note that subnets like 192.168.1.1/24 are invalid!
