Description:
------------
When given network addresses (partial ip addresses)*),
ip2long() calculates erratic values:

Input        Output           dechex    should be
192          int(192)         c0        c0000000
192.168      int(-1073741656) c00000a8  c0a80000
192.168.1    int(-1062731775) c0a80001  c0a80100

*) you will need this to convert 192/8, 192.168/16 etc
   network addresses.

Reproduce code:
---------------
$net=ip2long("192");
echo dechex($net)."\n";

$net=ip2long("192.168");
echo dechex($net)."\n";

$net=ip2long("192.168.1");
echo dechex($net)."\n";


Expected result:
----------------
c0000000
c0a80000
c0a80100


Actual result:
--------------
c0
c00000a8
c0a80001

tested on different OS'es.

I've now read the documentation of inet_addr(), so this is a feature. Maybe it should be documented.

Yup, it should be.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
