Indeed so. However the current behaviour has neither the merit of being
traditional nor the merit of being logical:

=> select '10.1'::cidr;   cidr     
-------------10.1.0.0/16
(1 row)

=> select '128.1'::cidr;    cidr     
--------------128.1.0.0/16
(1 row)

=> select '192.1'::cidr;    cidr     
--------------192.1.0.0/24
(1 row)

Having the behaviour be dependent on which part of the IP space is used
is a total nonsense on the modern, CIDR, internet! The C in CIDR even
stands for "Classless", so how can you ever justify introducing _new_,
non-traditional, dependencies on the traditional classes?
