You don't need views for this, because you shouldn't be getting any
queries from anywhere other than your local network. Simply configure
your server as a master for your forward zone and the reverse zone for
10.in-addr.arpa. Your server will answer with this information for your
servers, and recurse out to the Internet for everything else (there's no
need to forward to your ISP's DNS, that just adds an extra hop and point
