A domain name system (DNS) server. The domain name system server comprises a processor, a memory, and an application stored in the memory. When executed by the processor, the application receives an invalid domain name system address query and, in response to the invalid domain name system address query, returns a query response comprising a loop-back internet protocol address and a time to live value of less than about ten seconds.
