Abstract
A method for providing access to an Internet resource includes registering a surrogate nameserver to be an authoritative nameserver in a DNS network, receiving at the surrogate nameserver a DNS query, maintaining at the surrogate nameserver a cache that includes a resolution of the DNS query, and executing at the surrogate nameserver a policy code to make a determination of validity of one or more of the DNS query and the cached resolution.
