I do not understand the question fully but I would point him to the RIS itself. If this is a general question we could do a specialised query to the RIS for it. But not complicate riswhois. Small is beautiful.

Right, that's also what I had in mind; RISwhois provides a first quick overview, an overal looking glass on various RRC bgp tables. More complex queries, analysing updates, combining data from different prefixes, are out of scope, should be answered from RIS DB. -- Rene
