Previous Comments: ------------------------------------------------------------------------ [2007-09-01 18:29:38] derick@php.net Confirmed, and testing a patch. ------------------------------------------------------------------------ [2007-09-01 18:10:25] jr-php2 at quo dot to Description: ------------ On 64-bit platforms, ip2long() returns a positive result for IP addresses >= 128.0.0.0. This is expected. However, there is *one* case in which it will return a negative result: when the specified address is 255.255.255.255. This inconsistency doesn't make sense. Yes, the documentation does say that ip2long() returns -1 for 255.255.255.255, but that should only be the case on 32-bit platforms, where all addresses >= 128.0.0.0 return a negative result. Reproduce code: --------------- echo "ip2long('255.255.255.254') = ", ip2long('255.255.255.254'), "\n"; echo "ip2long('255.255.255.255') = ", ip2long('255.255.255.255'), "\n"; Expected result: ---------------- ip2long('255.255.255.254') = 4294967294 ip2long('255.255.255.255') = 4294967295 Actual result: -------------- ip2long('255.255.255.254') = 4294967294 ip2long('255.255.255.255') = -1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42512&edit=1
