Abstract
A technology is described for prioritizing DNS name resolutions requests received from DNS resolvers. An example method may include receiving a DNS name resolution request addressed to a DNS name server from a DNS resolver. The DNS resolver associated with the DNS name resolution request may be identified as a known DNS resolver or an unknown DNS resolver, where a known DNS resolver may have DNS resolver characteristics that correspond to a valid DNS resolver. The DNS name resolution request may be prioritized according to the identity of the DNS resolver as a known DNS resolver or an unknown DNS resolver. The DNS name resolution request may then be provided to the DNS name server according to the priority assigned to the DNS name resolution request.
