IP Neo-colonialism: Geo-auditing RIR Address Registrations

Allocation of the global IP address space is under the purview of IANA, who distributes management responsibility among five distinct Regional Internet Registries (RIRs). Each RIR is empowered to bridge technical (e.g., address uniqueness and aggregatability) and policy (e.g., contact information and IP scarcity) requirements unique to their region. Despite the critical policy and technical importance of IP address allocation, little systematic effort has analyzed fine-grained geographic registration information, much less its accuracy. In this work, we examine all IPv4 address information across all five RIRs to characterize where addresses are physically registered and the extent to which these registrations cross RIR region boundaries. We then perform an active measurement IP geolocation study to validate registration geo-information accuracy -- in essence an ``audit'' of the registries. While we find the registration locations to largely be consistent with our geolocation inferences, we show that some RIRs have a non-trivial fraction of prefixes that are used both outside of the RIR's region and outside of the registered country's region. Such discrepancies may warrant further investigation. Speaker: Robert Beverly
