survey on BGP damping
by Beichuan Zhang 12 Dec '03

12 Dec '03

Hi, We are conducting a survey of BGP damping deployment and would greatly appreciate if you could take a few minutes to answer the following questions. There are a number of interesting results and various recommendations for damping settings. However, we have found only limited information on who does(does not) deploy damping and what parameter settings are selected in practice. If you are willing to participate, please send replies directly to us. We will collect the results (removing any private information regarding specific sites) and post the results to the list. Thanks! --- beichuan (1) Does your AS have BGP route flap damping turned on? * Yes * No (please skip to comments) (2) What damping parameters do you use? * Cisco Default * Juniper Default * RIPE recommendation * Customized (3) On which links do you enable damping? * To customers only * To providers * To peers * All the above (4) Comments Please tell us more such as: What kind of network are you managing (any specific names will be removed in the published study)? Why (why not) do you enable damping? If you enable damping, why did you choose your current parameters? Has your site seen specific problems that were prevented by damping (or caused by damping)? We welcome any other comments you feel are relevant. Thanks!

New Statistics Format Released
by Shane Kerr 08 Dec '03

08 Dec '03

Dear Colleagues, The RIPE NCC has been working with the other Regional Internet Registries (RIRs) - APNIC, ARIN, and LACNIC - to provide Internet number resource statistics in a common format and location. The RIR Statistic files summarise the current state of Internet number resources, and are intended to provide a snapshot of their status without transactional or historical details. The following changes will be made to the existing statistics files: - Addition of IPv6 allocations - Addition of Early Registry Transfer (ERX) IPv4 networks - Addition of Provider Independent (PI) assignments - MD5 checksum provided for verification - New directory - Minor changes in format The statistics in the new format are available at: ftp://ftp.ripe.net/pub/stats/ripencc/new/ And the statistics in the current format are available at: ftp://ftp.ripe.net/pub/stats/ripencc/ The RIPE NCC will continue to produce the statistics in the current and new format until 5 January 2004. On this date, the statistics will be in the new format at: ftp://ftp.ripe.net/pub/stats/ripencc/ Statistics previously generated will be available at: ftp://ftp.ripe.net/pub/stats/ripencc/old/ Documentation of the format of these files may be found at: ftp://ftp.ripe.net/pub/stats/ripencc/new/RIR-Statistics-Exchange-Format.txt -- Shane Kerr Software Engineering Department Manager RIPE NCC

Deprecation of "cross-nfy:" and "cross-mnt:" attributes in the RIPE Whois Database
by Katie Petrusha 05 Dec '03

05 Dec '03

[ Apologies for duplicate messages ] Dear colleagues, "cross-nfy:" and "cross-mnt:" attributes will be deprecated in the RIPE Whois Database by 1 February 2004. The RIPE Whois Database previously had a cross notification mechanism. This mechanism used "cross-nfy:" and "cross-mnt:" attributes of route and aut-num objects to notify particular maintainers and contacts when an overlapping route object had been added or removed. In May 2003, this mechanism was deprecated, as it is already covered by Routing Policy System Security functionality. In March 2003, the proposal was circulated to deprecate "cross-nfy:" and "cross-mnt:" attributes in the RIPE Whois Database as they are no longer needed: http://www.ripe.net/ripe/mail-archives/db-wg/2003/msg00035.html Approximately 180 aut-num and 620 route objects will be affected by this change. These objects should be modified before 1 February 2003 and the "cross-nfy:" and/or "cross-mnt:" attributes should be removed from them. As soon as these attributes have been deprecated, they will not be accepted in the RIPE Whois Database. Therefore, we encourage everyone to make the necessary modifications in advance. The RIPE Database Administration will update the objects still requiring modifications to change deprecated attributes into "remarks:" attributes. No individual notifications will be sent. Relevant maintainers will be notified via the usual RIPE Whois Database notification mechanism. This information can be found at: http://www.ripe.net/db/cross_nfy_mnt_deprecation.html -- Katie Petrusha Software Engineering Department RIPE NCC

New IPv4 blocks allocated to RIPE NCC
by leo vegoda 18 Nov '03

18 Nov '03

Dear Colleagues, The RIPE NCC received the IPv4 address ranges 83.0.0.0/8 and 84.0.0.0/8 from the IANA in November 2003. We will begin allocating from these ranges in the near future. On 24 October 2003 there was a formal proposal to the RIPE Address Policy Working Group to lower the minimum allocation size from /20 to /21. For the text of this proposal please see: <http://www.ripe.net/ripe/mail-archives/address-policy-wg/2003/msg00189.html> It is likely that there will be formal consensus on this proposal in the near future. Consequently, the minimum allocation size for these blocks has been set at /21. Nonetheless, the RIPE NCC will not make /21 allocations from these blocks until after there is formal consensus to do so. You may wish to adjust any filters you have in place accordingly. More information on the IP space administered by the RIPE NCC can be found on our web site at: <http://www.ripe.net/ripe/docs/smallest-alloc-sizes.html> Kind regards, -- leo vegoda RIPE NCC Registration Services Manager

by RIPE NCC Training 13 Nov '03

13 Nov '03

------- Dear Colleagues, [apologies for duplicate postings] As a service to its members the RIPE NCC offers the "Routing Registry Training Course". The main objective of the "Routing Registry Training Course" is to familiarise the LIRs with the features of the Routing Registry, while introducing the relevant tools and services of the RIPE NCC. The course also offers practical exercises. OVERVIEW OF TOPICS COVERED IN THE COURSE: - Routing Registry as a part of the RIPE Whois Database and the Internet Routing Registry (IRR) - Specifying routing policies using (RPSL) Routing Policy Specification Language and the RtConfig tool - IRRToolSet - Routing Information Service (RIS) - Routing Registry Consistency Check Project Please note that this is an advanced course. It will: - NOT teach the basics of routing - NOT teach the basics of RIPE Database operations, - NOT describe how to receive Internet resources from the RIPE NCC - NOT describe how to operate a Local Internet Registry (LIR) The target audience of the course are technical staff of LIRs: e.g. network operators, engineers etc. This course is not intended for administrative or management staff (e.g. Hostmasters) . It is assumed that all attendees will be familiar with Border Gateway Protocol routing and with the RIPE Database (i.e. creating/modifying objects). This course is based on interactive exercises in a local network set-up. Please bring your laptops equipped with the following: - A working Ethernet card, - Three meters of Ethernet cable, - A secure connection client, - A web browser. Please be prepared to share your laptop (or at least allow another attendee to "look over your shoulder") if necessary. The Routing Registry Training Course is conducted in the English language and is free of charge, since it is covered by the membership fee. More information about the Routing Registry Training Course can be found at: http://www.ripe.net/training/rr/ REGISTRATION: You can register for a Routing Registry Training Course at the following URL: http://www.ripe.net/cgi-bin/trainingform.pl.cgi Or by completing the registration form at the end of this e-mail and replying to <training(a)ripe.net> . In order to register for a Routing Registry Training Course you must be an employee of an LIR and either: - be an LIR contact - be confirmed by an LIR contact LIR contacts are those employees of an LIR who are registered with RIPE NCC as authoritative contact persons.

The maintenance work will start at 12:00 UTC (13:00 Amsterdam time) on 10 November 2003 and expected to last 2 to 3 hours. We apologise for the inconvenience caused. Please do not hesitate to contact <ripe-dbm(a)ripe.net> for any questions. Best regards, -- Engin Gunduz RIPE NCC

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 -----
