+## How clients are identified
+
+The `X-Forwarded-For` and `Remote-Addr` HTTP headers are used to uniquely identify client IP addresses for throttling.  If the `X-Forwarded-For` header is present then it will be used, otherwise the value of the `Remote-Addr` header will be used.
+
+If you need to strictly identify unique client IP addresses, you'll need to first configure the number of application proxies that the API runs behind by setting the `NUM_PROXIES` setting.  This setting should be an integer of zero or more.  If set to non-zero then the client IP will be identified as being the last IP address in the `X-Forwarded-For` header, once any application proxy IP addresses have first been excluded.  If set to zero, then the `Remote-Addr` header will always be used as the identifying IP address.
+
+It is important to understand that if you configure the `NUM_PROXIES` setting, then all clients behind a unique [NAT'd](http://en.wikipedia.org/wiki/Network_address_translation) gateway will be treated as a single client.
+
+Further context on how the `X-Forwarded-For` header works, and identifing a remote client IP can be [found here][identifing-clients].

 The throttle classes provided by REST framework use Django's cache backend.  You should make sure that you've set appropriate [cache settings][cache-setting].
