 [2016-03-08 14:08 UTC] bugs dot php dot net at majkl578 dot cz
Description:
------------
Although whole 127.0.0.0/8 range is reserved, PHP only (and incorrectly) validates 127.0.0.1/32. I.e. 127.0.0.2 or 127.0.1.1 should be also treated as reserved range, but they are not currently.

Test script:
---------------
var_dump(filter_var('127.0.1.1', FILTER_VALIDATE_IP, FILTER_FLAG_IPV4 | FILTER_FLAG_NO_RES_RANGE));

Expected result:
----------------
bool(false)

Actual result:
--------------
string(9) "127.0.1.1"
