Install a caching DNS server. I'm sure there's some stand-alone
forward-only caching DNS servers out there, however the only method to
do this that I've tried is reconfiguring BIND to do it.
Is there a 'howto' somewhere for this? I've often thought of doing this, but I'm
definitely no bind guru.
I did a quick Google search for local caching. I gather that using Bind for this
is rather complicated for the user not experienced in Bind. Would you recommend
using Dan Bernstein's DNS cache - part of his djbdns tools for this?
It's been a while since I looked, but I think it's simple enough if you
take a quick skim through the administrator's reference guide available
at http://www.nominum.com/content/documents/bind9arm.pdf or maybe even
the FAQ at http://www.isc.org/sw/bind/FAQ.php
