[Apologies for duplicate emails] Dear All, RIPE NCC are pleased to announce the following RIS features: ============================================= * New Plots added to the RISreport The RISreport creates plots on a daily basis by using data from the RIS database. The new plots are generated per RRC and for the RIS as a whole: 1. AS number distribution -Origin-only ASes: ASes only seen to the right of AS paths -Transit ASes: ASes not seen exclusively to right of AS paths -Private: ASes designated for private use (64512 - 65534) -Other: ASes in ranges held or reserved by IANA or designated for experimental use 2. Average AS path length -Mean -Standard Deviation -Ratio (Mean/Standard Deviation) 3. Distribution of AS path length URL: http://www.ris.ripe.net/risreport/ (Click on "Totals" for each RRC or "All RRC boxes" at the bottom of the page) -------------------------------- * "RIS Martians" We provide now daily lists of Martians seen by RIS. We use the prefixes listed in Bill Manning's Internet Draft: "Documenting Special Use IPv4 Address Blocks that have been registered with IANA" (http://www.isi.edu/~bmanning/dsua.html) for our definition of Martians. URL: http://www.ris.ripe.net/martians/ -------------------------------- * "BGP Traffic Hot Spots" by the RIS These are daily lists of prefixes for which high BGP announcement or withdrawal activity has been observed by our Remote Route Collectors (RRC). We provide the lists per RRC and for the entire RIS. This is a list you don't want to be on ;) URL: http://www.ris.ripe.net/topten/ -------------------------------- * RIS Prefix Statistics Monthly lists of the number of prefixes seen by each RRC and the entire RIS. URL: http://www.ris.ripe.net/prefix-stat/ -------------------------------- * Addition to the RIS Help Pages: "BGP Cheat Sheet" Current Sections: -The Community Attribute -Brief Overview of BGP Routing Instability -Route Flap Damping/Dampening Please send your comments and suggestions to ris@ripe.net. More topics will be added later.
