Alternatively, you can use OpenDNS's servers. See www.opendns.com.
OpenDNS is very easy (just use their IP addresses), and quite fast. On
the other hand, caching can be fast too, and give you slightly more
security, as you'll be sending less requests, thus making traffic
analysis a tad more labor intensive. Would you concur, Matt?
