If someone is using a proxy on their local machine (perhaps to speed
up network access), that may *BE* the real IP (v6) address (localhost)
as defined by your function. If more than one of
$_SERVER['HTTP_CLIENT_IP']
$_SERVER['HTTP_X_FORWARDED_FOR']
and $_SERVER['REMOTE_ADDR']

are defined, it is not always obvious which one is "real". The
first two can be IP addresses in someone's local network that are
not reachable from the outside. The first two can also be faked.
I recommend logging all three.
