4778 Bogons Observatory
Bogon prefixes and Bogon Autonomous System numbers (ASes) have been well-known concepts within the networking community for the past twenty years. However, their precise definitions remain somewhat unclear.
In this presentation, we provide definitions of bogon prefixes and ASes, and present a methodology for identifying them. Additionally, we provide:
• an open-source repository containing the implementation of this methodology, allowing users to detect bogons using their own infrastructure or public routing data collection platforms such as RIPE RIS and RouteViews
• access to a service that enables users to monitor real-time bogon data collected from hundreds of globally distributed sources
Our methodology identifies all possible bogon types, including full-bogon prefixes and bogon ASes present anywhere in the AS Path, and assists network operators in detecting routing misconfigurations.
Our findings indicate that the bogon phenomenon has been largely underestimated, since only a fraction of its true extent is known.
Project's goal: An internet with fewer bogons.
