Quality-of-service management for Domain Name Service comprising identifying top-talking recursive resolvers of Domain Name Service packets, determining a baseline volume of Internet traffic, extrapolating future projected normal traffic volume, and allocating electronic communication network resources proportionally in accordance with the projected volume. Top-talking recursive resolvers not using a desired protocol can be induced to use that protocol, and a persistent session can be established with the top-talking recursive resolvers, such as by use of a TC flag set. The stateful nature of a TCP conversation allows rate-limiting and traffic volume management. A source IP address can be identified as apparently comprising a forged source IP address based on whether the desired transmission protocol is employed, and packets with the forged source IP address can be discarded.
