Say, if you have a /8 netmask, the 'cidr' type requires that all the
24 rightmost bits are zero. inet does not have this requirement.
E.g:
db=# select '255.0.0.0/8'::cidr;
255.0.0.0/8
db=# select '255.1.0.0/8'::cidr;
ERROR: invalid cidr value: "255.1.0.0/8"
DETAIL: Value has bits set to right of mask.
And inet allows this:
db=# select '255.1.0.0/8'::inet;
255.1.0.0/8
Hope that helps.
