When I use long2ip or binary arithmetics  it's does not work correctly.
e.g
long2ip(3813441731) results 128.0.0.0 where this result should be 
227.76.128.195

when I'm trying to write analog of this function using binary arithmetics:

$ip = 3813441731;
$a = ($ip >> 24) & 0xff;
$b = ($ip >>16) & 0xff;
$c = ($ip >> 8) & 0xff;
$d = $ip & 0xff;
print "$a.$b.$c.$d";
-------------
I have same result:
128.0.0.0
What I do wrong?
I've try this on FreeBSD 3.5-STABLE, FreeBSD 4.2-RC2 and FreeBSD 
4.4-RELEASE

Works fins for me on Linux/FreeBSD 4.4 with PHP 4.1.0RC1 and PHP 4.2.0dev.
So it seems to be fixed. Can you try the RC from www.php.net/~ssb/php-4.1.0RC1.tar.gz. If it is not fixed there, please reopen this report.
