ID: 27710 User updated by: phpbug at labres dot at Reported By: phpbug at labres dot at Status: Open Bug Type: Math related Operating System: Linux, FreeBSD PHP Version: 4.3.4 New Comment: I've now read the documentation of inet_addr(), so this is a feature. Maybe it should be documented.

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 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27710&edit=1
