But there are also a lot of reserved ranges. FILTER_FLAG_NO_PRIV_RANGE (IP not from private ranges) fc00::/7 // unique-local addresses (rfc4193) FILTER_FLAG_NO_RES_RANGE (IP not from reserved ranges) ::/128 // unspecified address (rfc4291) ::1/128 // loopback address (rfc4291) fe80::/10 // link local unicast (rfc4291) 2001:db8::/32 // documentation addresses (rfc3849) 5f00::/8 // 6Bone 3ffe::/16 // 6Bone ::ffff:0:0/96 // IPv4-Mapped addresses (rfc4291) 2001:10::/28 // ORCHID addresses (rfc4843) ::/0 // default unicast route address FYI the following ranges are implemented for IPv4 in logical_filters.c FILTER_FLAG_NO_PRIV_RANGE (IP not from private ranges) 10.0.0.0/8 // private use network (rfc1918) 172.16.0.0/12 // private use network (rfc1918) 192.168.0.0/16 // private use network (rfc1918) FILTER_FLAG_NO_RES_RANGE (IP not from reserved ranges) 0.0.0.0/8 // "this" network (rfc1700) 169.254.0.0/16 // link local network (rfc3927) 192.0.2.0/24 // test net (rfc3330) 224.0.0.0/4 // Multicast (rfc3171) 240.0.0.0/4 // Reserved for Future Use (rfc1700) ------------------------------------------------------------------------ [2009-03-03 01:20:16] [email protected] According to the RFC I saw, the indicated ranges are the only ones identified as private. ------------------------------------------------------------------------ [2009-02-26 11:17:20] valli at icsurselva dot ch Sorry, I've checked the wrong file when I wrote the last comment. Now I've seen your fixes. But there are a lot more ranges to check (not only fc00::/7) At least the following IPv6 ranges should match when FILTER_FLAG_NO_RES_RANGE is set (rfc5156): ::/128 // unspecified address (rfc4291) fe80::/10 // link local unicast (rfc4291) 2001:db8::/32 // documentation addresses (rfc3849) 5f00::/8 // 6Bone 3ffe::/16 // 6Bone ------------------------------------------------------------------------ [2009-02-24 07:55:51] valli at icsurselva dot ch Can't find any code in the snapshots regarding this issue. Will this be fixed in php-5.3? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
