I have in my internal view mostly systems that are not visible from the
outside but my internal view has direct access to the world with regards
to DNS. I don't see any risk in that , except the predictability of
RBL-lookups as mentioned elsewhere.
Speed is much improved, even with a standard ADSL line I have better
performance than by forwarding to the ISP DNS server.
