It dates back from the very early days. It's not generally very nice in
IPv4, and people who use 192.168.0/24 are fine, but people who use, say
192.168.2/24 might get somewhat confused. (expands to 192.168.0.2/24,
which is, of course, 192.168.0.0/24).
My personal feeling is not to allow it, as it can confuse, and produce
hard-to-spot bugs if you mistype something.
But that's me.
