Announcing RISwhois - RIPE NCC IPv4/IPv6 address to origin mapping
by Rene Wilhelm 06 Nov '03

06 Nov '03

[Apologies for duplicate mails] Dear All, RIPE NCC is pleased to announce RISwhois, a new interface to the BGP data collected by the Routing Information Service (RIS). Using a set of ten Remote Route Collectors (RRCs) installed at different locations around the world, the RIS collects BGP information from over 200 IPv4 and IPv6 peers. RISwhois complements our existing prefix query and looking glass tools by providing a higher level view over an entire set of RRC routing tables. The service looks up IPv4 or IPv6 addresses in the most recently collected full RIB dumps and reports the prefixes and origin AS numbers that match the specified IP, as well as the RRCs on which the prefixes were seen. This can help users in obtaining a quick answer on route visibility (i.e. where is it seen, how widely does it spread) and in assigning origin AS numbers to IP numbers in applications such as traceroute. RISwhois listens to the whois port (port 43) and outputs data in a format very similar to the route objects specified in RPSL. Thus applications that, to date, consult a routing registry, like whois.ra.net, can easily obtain more accurate IP to AS assignments by contacting the RISwhois server, riswhois.ripe.net, instead. For example, a study in the context of RIPE NCC's Test Traffic Measurements found 21% of a set of unique IPs unmatched when using the routing registry vs. only 1% unmatched when using RIS data. For more information see: http://www.ripe.net/ris/riswhois.html Please send your comments to ris(a)ripe.net. Best regards, For the RIS team, -- Rene =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Rene Wilhelm RIPE Network Coordination Centre Email: wilhelm(a)ripe.net Amsterdam, the Netherlands Phone: +31 20 535 4444 http://www.ripe.net/ris =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

[kc@caida.org: requesting hard data sources on ramifications of verisign wildcard] (fwd)
by Henk Uijterwaal (RIPE-NCC) 20 Oct '03

20 Oct '03

FYI and apologies for duplicate mails. ----- Forwarded message from k claffy <kc(a)caida.org> ----- Date: Thu, 16 Oct 2003 12:26:15 -0700 From: k claffy <kc(a)caida.org> Subject: requesting hard data sources on ramifications of verisign wildcard To: nanog(a)nanog.org as already mentioned, fascinating public policy theatre is going on in DC on the verisign wildcard issue, see http://secsac.icann.org/ [all video and even transcripts of both meetings online. go icann.] you are encouraged to read through all of it before making public comments on this issue at nanog. (or, hope springs eternal, to this list.) caida has the following request on behalf of icann's secsac committee [an exceptionally competent group who is approaching this issue with impressive speed, equaniminity, and integrity. http://www.icann.org/committees/security/ i believe we're in good hands here. let's give the process a chance and constructively contribute where we can.] a common theme over the last week is an admitted lack of hard data [rather than lists of theoretical breakages, and anecdotal evidence, and predictions] from the operational community on actual loss of stability in Internet performance or functionality. david from XO gave an outstanding talk on 7 oct, http://www.icann.org/presentations/shairer-secsac-dc-07oct03.ppt but, as with many other providers, he deployed the bind patch within 24 hours so he didn't really have useful hard data to put on the table. i get similar comments from others. ben from harvard also gave some hard alexa data, fwiw http://www.icann.org/presentations/edelman-secsac-dc-15oct03.ppt but from a specific vantage point. we need more of these. icann's secsac committee is in a much stronger position to provide technically sound and equitable guidance if we can provide them with as specific, concrete examples (*hard data*) that indicate extent of various types of breakage. please save the arguments regarding the legitimacy and short notice of this request until you've read the hours of discussion about it that has already occurred among many qualified folks in DC (and in any case the meta-issue still stretches AUP of nanog list). the inconvenient reality is that the secsac committee needs concrete data (imagine), in addition to bulleted lists of things that break, for the policy process to work most effectively here. and nanog is in a position to make a difference. you are hereby encouraged to do so. please send any hard data reflecting observed ramifications on security and stability of Internet infrastructure to secsac-comment(a)icann.org no hard data will be refused service k ----- End forwarded message -----
