Abstract:
A method of filtering a plurality of DNS queries, wherein each DNS query includes a query name and a resource record type, includes defining a filter rule including a domain name, a filter type, and a throttle percentage and forming a filter file including the filter rule. The method also includes transmitting the filter file from a server to a plurality of filter proxies, transmitting the filter file from each of the plurality of filter proxies to one or more processing engines, and receiving the plurality of DNS queries at one of the one or more processing engines. The method includes determining a match between the domain name and the query name and between the resource record type and the filter type for a subset of the plurality of DNS queries, and blocking a predetermined percentage (equal to the throttle percentage) of the subset of the plurality of DNS queries.
