Multiple Roots simply need context
by Chris Davis 19 Mar '01

19 Mar '01

There is no problem in having hundreds or thousands of multiple root servers for DNS. We have a problem with CONTEXT. There is no existing way to ascertain the context from which users are resolving domain names. Solution: DNS Context Servers... DNS operators subscribe their machines to the DNS context they want. In one context, ".xxx" can resolve via new.net, in another context, ".xxx" resolves via one of the other .xxx providers. To keep ICANN and friends happy, ICANN could be the "default" context. Help calls then have one and only one additional question: "To which DNS context do you subscribe?" Context servers are pretty obviously where things are headed. Sooner or later, some new.net company is going to "take." If we already have DNS context servers in place, life will be much easier when an alternative TLD provider does succeed. -Chris Davis --not really selling private address space, that was a joke --not a fan of new.net's plugin, since it breaks ping, traceroute, and tradition

NANOG 22!
by Susan Harris 19 Mar '01

19 Mar '01

Greetings everyone - the next NANOG meeting will be held May 20-22 in Scottsdale, Arizona, at the DoubleTree Paradise Valley. Our local host will be CenterGate Research Group. You'll find a Call for Presentations below. Thanks for being patient while we made final arrangements for the conference. Meeting registration begins April 2 and details about hotel reservations will follow shortly. Thanks also for the comments about NANOG and Merit that many of you made on the list after the Atlanta meeting. We've written up a FAQ that answers some of your questions: http://www.nanog.org/faq.html Questions and comments are welcome - please send them to nanog-support(a)nanog.org, so that we can keep the main list focused on operational issues. ============================================================================== * * * * * * * * * * * * * * * * * CALL FOR PRESENTATIONS * * NANOG 22 * * May 20 - 22, 2001 * * * * * * * * * * * * * * * * * The North American Network Operators' Group (NANOG) will hold its 22nd meeting in Scottsdate, Arizona, between May 20-22, 2001. The meeting will be hosted by CenterGate Research Group. NANOG conferences provide a forum for the coordination and dissemination of technical information related to large-scale (i.e., national/international) Internet backbone networking technologies and operational practices. NANOG meetings, held three times each year, include two days of short presentations, plus afternoon/evening tutorial sessions. Meetings are informal, with an emphasis on relevance to current backbone engineering practices. The conference draws over 600 participants, mainly consisting of engineering staff from large national service providers, and members of the research and education community. Now in its sixth year, NANOG evolved from the NSFNET "regional-techs" meetings, where technical staff from the regional networks met to discuss operational issues of common concern. With the emergence of the commercial Internet, NANOG meetings evolved to include a broader base of providers, network operators, and researchers. The meeting will be held at the DoubleTree Paradise Valley. For more information about NANOG meetings, schedules, and logistics, see: http://www.nanog.org ------------------------------------------------------------------------------ CALL FOR PRESENTATIONS NANOG invites presentations on backbone engineering, coordination, and research topics. Presentations should highlight issues relating to technology already deployed or soon to be deployed in core Internet backbones and exchange points. Previous meetings have included presentations on: - Backbone traffic engineering - Coordination of inter-provider QoS - Deployment experience with queueing disciplines (CAR, RED) - Inter-provider security and routing protocol authentication - Routing scalability in backbone infrastructures - Security issues for the Internet core - Routing policy specification and backbone router configuration - Building large-scale measurement infrastructure - Cooperative inter-provider caching - Alternatives to hot-potato routing - Recommendations on queue management and congestion avoidance - Experience with differentiated services - Reports from next-generation networks (CANARIE, Internet2)) - Inter-domain multicast deployment - Backbone network failure analysis Tutorials have covered topics such as: - BGP case studies - MPLS fundamentals - External route selection - IP multicast technologies - Distributed content caching in large IP networks ------------------------------------------------------------------------------ HOW TO PRESENT Submit an informal one- or two-paragraph abstract describing the presentation in email to nanog-support(a)nanog.org. The deadline for proposals is April 16, 2001. While the majority of speaking slots will be filled by April 16, a limited number of slots will be available after that date for topics that are exceptionally timely and important. Submissions will be reviewed by the NANOG Program Committee, and presenters will be notified of acceptance by April 23, 2001. NANOG also welcomes suggestions/recommendations for tutorials, panels and other presentation topics. ---------------------------------------------------------------------------

Why do you feel it appropriate to go against their wishes?

Is there a (fairly) recent exploit for common ftp daemons going around lately? In the past several days, I've seen a very noticeable jump in the number of people attempting anonymous ftp logins. Typically I noticed it once or twice a week, and usually single attempts, but now they're coming in every few hours and they each make 4 attempts within a second (which is one per IP bound to the box I'm watching). It looks like it has to be some kind of script. Anyone else seeing any noticeable increases like this? -c

BGPv5
by John 19 Mar '01

19 Mar '01

Has anyone been involved with the IETF on submitting information on BGP-5? I am trying to understand how congestion control would be best handled. Would it be possible to add something additional in the OPEN message rather than just having MP_NLRI_REACH and MP_NLRI_UNREACH or better yet run them in parallel. If we replace the encoding of the NLRI and then withdraw the routes with these 2 attributes wouldn't that make it work? Thanks John
