Disclosed is a method, a computer system, and a computer-readable media product that contains a set of computer executable software instructions for directing the computer to execute a process for policy-based operation of a DNS server apparatus to manage traffic due to undesirable mail or requests for electronic documents. The policies operate according to owners, regions, or countries controlling source IP addresses and deterministically select from a plurality of non-equivalent replies to be sent to the source IP address. Accumulating previous activity records may assist in determining which traffic may be usefully deferred or suppressed. The process includes withholding certain information from certain DNS servers seeking IP addresses to improve overall security and integrity of the Internet.
