ARIN is allocating from 72.0.0.0/8
by Leslie Nobile 16 Sep '04

16 Sep '04

Hello- ARIN began allocating IP address space from 72.0.0.0/8 on Sept 10, 2004. We anticipate that we will be making allocations from 71.0.0.0/8 in the near future. These 2 IP address blocks were issued to ARIN by the IANA on Aug. 2, 2004. This is a reminder message that you may need to adjust any filters you have in place for these two blocks accordingly. For informational purposes, a list of ARIN's currently administered IP blocks can be found under "CIDR Blocks" at: http://www.arin.net/statistics/index.html Regards, Leslie Nobile Director, Registration Services American Registry for Internet Numbers (ARIN)

.255 and .0 addresses
by Volodymyr Yakovenko 13 Sep '04

13 Sep '04

Dear Colleagues, I am not quite sure that routing-wg@ is a right place to ask my question, but nothing more convenient came to my mind :-) I am trying to push one BIG telecom equipment vendor TAC to consider wrong situation with assignment of IP addresses like xxx.xxx.xxx.0 and xxx.xxx.xxx.255 from dynamic IP pools bigger than or equal to /24. Quick googling has not shown any STD or BCP documents, which could be used as reference, but has shown number of pages, saying something like "do not use .0 or .255 addresses, it could cause problems". Our small research has shown that some sites are not reachable from .255 and .0 addresses. Are there any published documents or strong research results which could be used as reference point to illustrate this problem existance? -- Regards, Volodymyr.

by leo vegoda 13 Sep '04

13 Sep '04

Dear Colleagues, The RIPE NCC received the IPv6 address range 2001:5000::/20 from the IANA in September 2004. 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: <https://www.ripe.net/ripe/docs/smallest-alloc-sizes.html> Regards, -- leo vegoda Registration Services Manager RIPE NCC

Draft agenda for RIPE 49
by Joao Damas 08 Sep '04

08 Sep '04

Here is the first draft of the agenda for the Routing Working Group meeting during the RIPE 49 meeting in Manchester, UK. We will have a pretty full agenda this time, feeling up both slots. Regards, Joao Damas ISC RIPE Routing wg/love and caring department :-) Tue 21/Sept (16:00-17:30) A. Preliminaries (the chairs, 5 min) - introduction - participants' list - volunteering of scribe - jabber/irc interface - agenda bashing - RIPE 47 minutes - actions from earlier meetings - upcoming RIPE NCC routing registry courses B. Michael Behringer/Christian Panigl (45 min) "Transparency vs. Security in Core Networks: Pros and Cons" Abstract: This is meant to be a discussion session for the EOF presentation. What do RIPE attendees think about either approach? Is there a "best practice"? C. Mathew Williams (20 min) RIS update. D. Zhang Shu (20 min) intra-domain routing instability 1. The results of some intra-domain routing instability measurements that we did on two academic networks in Japan 2. The introduction of a system that we devoleped to measure intra-domain routing instability, which can also be used by network operators to monitor the routing of their networks. http://pe0.koganei.wide.ad.jp/rtanaly/ Proceedings of ACM SIGCOMM 2004 NetTS workshop: "Troubleshooting on Intra-Domain Routing Instability" Wed 22/Sept (11:00-12:30) E. Pedro Roque Marques (30 min) Title: BGP network design Description: This presentation will focus on a set of frequently asked questions that network operators have regarding the logical design of BGP networks. These include topics such as route reflector placement on a network and BGP configuration tradeoffs. F. Randy Bush (20 min) Happy packets What is the relationship between control plane instability and data planeinstability? G.

PAM2005 CFP
by Henk Uijterwaal (RIPE NCC) 05 Sep '04

05 Sep '04

(Apologies for duplicate messages) ************ PRELIMINARY CALL FOR PAPERS ***************** Passive & Active Measurement Workshop (PAM2005) Boston, MA Mar 31-Apr 1, 2005 ********************************************************** IMPORTANT DATES: * Paper Submission: October 8, 2004 * Author Notification: December 10, 2004 * Camera Ready: January 20, 2005 CONFERENCE INFORMATION PAM'05, the sixth PAM workshop, is a two-day event focusing on research and practical applications of passive and active measurement and analysis techniques. Original papers describing novel work-in-progress are invited from the research, provider, and other communities on topics including, but not limited to: * Active Network Measurements * Passive Network Measurements * Performance Metrics * Traffic Statistics * Measurement Visualization * New Measurement Approaches & Techniques * Deployment of Measurement Infrastructure * New Measurement Initiatives * Applications of Network Measurements * Network Measurements and Security * Network Troubleshooting using Measurements * Embedded and Reconfigurable Hardware for Network Measurements Student participation is strongly encouraged. PAM has a tradition of being a true workshop with lively discussion and active participation from all attendees. As such, we favor submissions reporting exciting on-going work. SUBMISSION INFORMATION To ensure PAM2005 is fresh and interesting, we are soliciting extended abstracts in the first instance. These should be at most FOUR pages in length in the standard IEEE double-column format. The abstracts should present work-in-progress, explaining the basic approach and motivation. Comprehensive results are not expected at this stage, although the authors should comment on the results they expect to obtain; there are 3.5 months between the abstract submission and camera ready deadlines. If selected for publication, authors will be expected to produce an 8-10 page paper including results and validation.
