This is natural, unless you specifically enter the zones for 192.168.8.* 
(forward and reverse) in your client DNS server (as slave or forward zones, 
see the bind manual for the latter, which I'd recommend in your case).

The explanation is simple: how is (your local) bind supposed to know which 
server to query for those domains, as the (public internet) root name servers 
won't reply for them (zones always take precedence over forwarders, so if you 
have a zone for ".", i.e. everything, in your named.conf, your forwarder is 
never queried for anything), and it has no other info on 
8.168.192.in-addr.arpa than to resursively look it up starting from a root 
name server, which won't answer but with a NXDOMAIN response.

If you remove the hints, there's only a forwarder left in your configuration, 
which in turn is always queried, and which can also properly resolve your 
domains.

Hope this explains stuff.
