An Empirical Study of "Bogo" Route Advertisements

An important factor in the robustness of the inter-domain routing system is whether the routers in Autonomous Systems (ASes) filter routes for "Bogon" address space - i.e., private address space and address space that has not been allocated by the Internet Assigned Numbers Authority (IANA). This paper presents an empirical study of bogon route announcements, as observed at eight vantage points on the Internet. On average, the authors observe several bogon routes leaked every few days; a small number of ASes also temporarily leak hundreds of bogon routes.
