Why the RIS?
•Many tools that debug Internet connectivity, e.g. Ping, TraceRoute, Protocol Analyzers, Router debug commands e.t.c. •Major drawback – No ‘history’. Only works with the current status and configuration •Another drawback – No perspective ‘mobility’ (exception: Looking Glasses, however, not all are available to the public and they only provide information about the AS where it’s installed)
