Byzantine fault tolerance of non-delay-based IP geolocation approaches

Ascertain whether alternative IP geolocation approaches—such as web mining of server locations, reverse DNS geolocation, IP range interpolation, traceroute/hostname-based mapping, and machine learning methods—can be adapted to provide Byzantine fault tolerance suitable for decentralized, adversarial environments.

Background

The paper surveys alternatives to delay-based geolocation, including web mining, DNS-based inference, traceroute-derived hints, IP range interpolation, and machine learning. While these methods may improve accuracy when combined with delay-based techniques, their resilience to adversarial manipulation is not established.

Because the proposed protocols target decentralized and potentially adversarial settings, establishing whether these non-delay-based methods can be made Byzantine fault tolerant remains an open question relevant to practical deployment.
