Using OpenDNS does not provide all the benefits of running your own DNS server where "benefits" includes fine grained control. Additionally OpenDNS has some behaviors that network admins aren't crazy about. OpenDNS will return an answer for queries with no authoritative match. For example, if you query `dig noexist.example.com @208.67.222.222` (that's an OpenDNS resolver IP), you'll get answer: 1 and an IP address. This is considered a "feature" by OpenDNS, but from a purist's perspective, it is a breakage. We do not run our own DNS server for client name-resolution, because we don't have any need for the control it provides. I acknowledge that some people do, however.
