Apologies, entered the wrong output values.
Expected result:
string(9) "127.0.0.1"
string(3) "::1"
bool(false)
bool(false)
bool(false)
bool(false)
Actual result:
string(9) "127.0.0.1"
string(3) "::1"
string(9) "127.0.0.1"
string(3) "::1"
string(9) "127.0.0.1"
string(3) "::1"
The IP address 127.0.0.1 might be a special IP - not quite sure if it
fits in
the private range, or the reserved range. Or perhaps, there should be a
special
range for this special cases.

Description:
------------
The 127.0.0.1 IP address is considered to be valid even when filtering
with either
the FILTER_FLAG_NO_RES_RANGE and FILTER_FLAG_NO_PRIV_RANGE flags.
This might be related with bug #47435.
Test script:
---------------
var_dump(filter_var('127.0.0.1', FILTER_VALIDATE_IP)); // true
var_dump(filter_var("::1", FILTER_VALIDATE_IP)); // true
var_dump(filter_var('127.0.0.1', FILTER_VALIDATE_IP,
FILTER_FLAG_NO_RES_RANGE)); // false
var_dump(filter_var('::1', FILTER_VALIDATE_IP,
FILTER_FLAG_NO_RES_RANGE)); // false
var_dump(filter_var('127.0.0.1', FILTER_VALIDATE_IP,
FILTER_FLAG_NO_PRIV_RANGE));
var_dump(filter_var('::1', FILTER_VALIDATE_IP,
FILTER_FLAG_NO_PRIV_RANGE));
Expected result:
----------------
