The thing is, it doesn't create a network, it creates a hybrid "network plus
host" which retains knowledge about the original host (that is, 192.168.1.1
rather than simply 192.168.1.0, if you enter "192.168.1.1/24").
That's what the OP meant with "networks-that-aren't-networks", and that's what
people are objecting to.
