[TYPO3-core] RFC Bug #11450: Install tool access check should take IPv6 loopback into account

[Steffen Kamper]

Hi,

the "private" adresses should be solved with some php tricks, this could 
be a way to be not fixed on 127.0.0.1
(t3lib_div::validIPv4($_SERVER['REMOTE_ADDR']) && 
filter_var($_SERVER['REMOTE_ADDR'], FILTER_VALIDATE_IP, 
FILTER_FLAG_IPV4, FILTER_FLAG_NO_PRIV_RANGE) === FALSE)
||
(t3lib_div::validIPv6($_SERVER['REMOTE_ADDR']) && 
filter_var($_SERVER['REMOTE_ADDR'], FILTER_VALIDATE_IP, 
FILTER_FLAG_IPV6, FILTER_FLAG_NO_PRIV_RANGE) === FALSE)
