Doug Madory on the Mysterious AS8003 Global Routing Story

Director of Internet Analyis at Kentik, Doug Madory, joins the Security Conversations podcast to shed light on the mysterious appearance of hundreds of millions of unused IPv4 addresses belonging to the US Department of Defense. Was it a BGP hijack, or something else?

Learn how this mystery went from chatter amongst network professionals on a NANOG mailing list to the subject of widely-read investigations by major news outlets including the Washington Post and Associated press.

Doug and host Ryan Naraine discuss the mechanics of “announcing” internet address space, BGP routing, the unusual timing of these announcements (in the last moments of the outgoing President’s administration), and the security and privacy implications of AS8003.
