Sorry, but what kind of hierarchy does it defeat? If client's query can't be satisfied from provider's DNS cache, and doesn't refer to domain which is hosted on ISP, then provider's DNS server will make first query to root DNS server, and then will walk down domain hierarchy (e.g. .ua -> .dp.ua -> atlantis.dp.ua). So setting client's DNS to directly query root servers defeats just the provider's DNS cache. > And there might be ISPs who disallow outgoing DNS connections to > somewhere else than their own DNS servers.
