I linked to OpenDNS last week, praising their service after Comcast’s own DNS servers had failed me for the last time. It ends up though that OpenDNS is a polarizing service — they’re both praised and scorned. One of the reasons they’re scorned is that they redirect requests to www.google.com to their own internal server before forwarding the request along to Google’s www.l.google.com. They also do wildcard matching for unregistered domain names, a move most DNS experts consider a no-no. They’re open about these “features” (e.g. here’s their explanation for the Google redirection), but I tend to take the side that any sort of “DNS+” service is worse than just plain DNS.
I think it’s worth keeping OpenDNS on deck for use in a pinch if your regular DNS server conks out, but I can’t recommend them for primary use.
