Previous Comments: ------------------------------------------------------------------------ [2020-09-17 11:15:31] kieran at supportpal dot com Perhaps a feature request for RFC 4007 support instead of a bug. inet_pton also fails with the address mentioned in the example. ------------------------------------------------------------------------ [2020-09-17 10:43:39] kieran at supportpal dot com Description: ------------ filter_var rejects IPv6 scoped literal addresses. Scoped literal addresses are described at https://en.wikipedia.org/wiki/IPv6_address#Scoped_literal_IPv6_addresses_(with_zone_index) [RFC 4007](https://tools.ietf.org/html/rfc4007): a common notation to specify the scope zone, an implementation SHOULD support the following format: <address>%<zone_id> where <address> is a literal IPv6 address, <zone_id> is a string identifying the zone of the address, and `%' is a delimiter character to distinguish between <address> and <zone_id>. Test script: --------------- https://3v4l.org/Lqnm0 <?php $ip = "fe80::3549:8417:2ad0:ef6a%4"; var_dump(filter_var($ip, FILTER_VALIDATE_IP)); Expected result: ---------------- return true Actual result: -------------- return false ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80116&edit=1
