No, nonsense. 240.0.0.0/4 is reserved, but 224.0.0.0/4 is not reserved. Therefore the behavior of your test script is expected.

Indeed, you're right. ------------------------------------------------------------------------ [2017-06-05 20:44:39] brianlmoon@php.net Description: ------------ The patch applied for https://bugs.php.net/bug.php?id=72972 removed the 240.0.0.0/4 block from the reserved list. RFC 6890 [https://tools.ietf.org/html/rfc6890] calls out 240.0.0.0/4 as a "Reserved" block. Bug https://bugs.php.net/bug.php?id=73653 mistakenly claimed that RFC 6890 does not list this as a reserved block. You will find it on page 12 of that RFC. Test script: --------------- $return = filter_var("224.0.0.2", FILTER_VALIDATE_IP, FILTER_FLAG_NO_RES_RANGE); var_dump($return); Expected result: ---------------- bool(false) Actual result: -------------- string(9) "224.0.0.2" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74699&edit=1
