Analysing the Energy Consumption of a DNS Resolver

Domain Name System (DNS) resolution, a fundamental component of Internet communication, plays a crucial role in how data centers function and deliver services to end-users. This article addresses a significant research gap in energy-efficient data center management by focusing on measuring and analysing DNS resolver energy consumption. We introduce a mathematical model to estimate the number of transmitted packets, conduct controlled experiments, and examine the energy impact of security mechanisms such as TLS handshakes and encryption/decryption processes. As part of this ongoing work, we aim to refine the model based on experimental results and leverage it to support the evaluation and optimization of DNS operations in data center environments.
