Then it would be better to disallow such things. The normal meaning
for "127.2" was always 127.0.0.2, and it was widely documented and
used (though perhaps in RFCs, not in POSIX). Some people use "10.1"
syntax all the time.

Any script which uses 127.2 to mean 127.2.0.0 is IMHO broken, though
I have never seen anything like that.

Rules always have been simple:
10	- 10.0.0.0
10.1	- 10.0.0.1
10.1.2	- 10.0.1.2

If it can't stay this way, lets remove this shortened notation
completely.
