 | Reverse Proxy IPs
 |--------------------------------------------------------------------------

-| If your server is behind a reverse proxy, you must whitelist the proxy IP
-| addresses from which CodeIgniter should trust the HTTP_X_FORWARDED_FOR
-| header in order to properly identify the visitor's IP address.
-| Comma-delimited, e.g. '10.0.1.200,10.0.1.201'
+| If your server is behind a reverse proxy, you must whitelist the proxy
+| IP addresses from which CodeIgniter should trust headers such as
+| HTTP_X_FORWARDED_FOR and HTTP_CLIENT_IP in order to properly identify
+| the visitor's IP address.
 |
+| You can use both an array or a comma-separated list of proxy addresses,
+| as well as specifying whole subnets. Here are a few examples:
+|
+| Comma-separated:	'10.0.1.200,192.168.5.0/24'
+| Array:		array('10.0.1.200', '192.168.5.0/24')
