At RIPE 46 we presented measurements about the effects of adding IPv6 glue to the root zone. As promised, we made more measurements and have written a document: http://www.nlnetlabs.nl/ipv6/publications/v6rootglue.pdf rvdp

[kc@caida.org: requesting hard data sources on ramifications of verisign wildcard] (fwd)

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 -----

Upcoming change of source AS for i.root-servers.net
by Johan Ihren 19 Oct '03

19 Oct '03

Friends, As part of the long term ambition to provide the Internet root nameservers with extremely stable homes in all possible respects we plan to change the source autonomous system for i.root-servers.net from AS8674 (NETNOD INTERNET EXCHANGE) to AS29216 (dedicated as I.ROOT-SERVERS.NET) We hope that after this change i.root-servers.net will never have to change source AS again. We intend to implement this change next week during the NANOG29 conference. Please note: a) This is a planned operation, not an emergency. b) We will not change the IP adress of the i.root-servers.net service, only the source AS. c) We will not change any of the several servers providing the i.root-servers.net service in any way. It will be the same servers at the same locations providing exactly the same service as usual. Regards, Johan Ihrén Autonomica

Hi, I don't know whether this was discussed on this mailing list before. I just subscribed and would like to hear your opinion about http://www.ietf.org/internet-drafts/draft-danisch-dns-rr-smtp-03.txt which describes the RMX records, a method to store authorization records about who is authorized to send e-mails with sender addresses of the zone. It is intended to protect against spam, worms, and such rubbish. regards Hadmut

Next phase in deploying anycast instances of k.root-servers.net
by Andrei Robachevsky 22 Sep '03

22 Sep '03

Dear colleague, After discussions at the last RIPE Meeting, we would like to clarify our current thinking about adding further anycast instances to k.root-servers.net. This message sets out the direction and further details the requirements for hosting such an instance and calls for expressions of interest from the Internet community to support this activity. I look forward to your support. Best regards, Andrei Robachevsky CTO, RIPE NCC General requirements and guidelines for expressions of interest for hosting a mirror instance of k.root-servers.net ============================================================== Introduction ------------ The RIPE NCC operates k.root-servers.net, one of the servers used as a name server for the DNS root zone. In order to further improve the distribution of the service in various Internet regions and its resilience against DDoS attacks the RIPE NCC is deploying mirror instances of the server worldwide as described in the ripe document "Distributing K-Root Service by Anycast Routing of 193.0.14.129" (RIPE 268). The first phase of this project included moving the cold standby instance of the server to service using anycast routing. This phase was completed in July 2003 and k.root-servers.net is currently deployed in two locations (LINX, London and AMS-IX, Amsterdam). The next phase will be mostly focused on the deployment of nodes with limited reachability in the RIPE NCC service region. The main motivation for this phase is: - Improving access to k.root-servers.net for a significant ISP community. - Isolating impact of an "external" DDoS attack. - Localising impact of a "local" DDoS attack. This document sets the direction and further details the requirements for hosting an instance of the k.root-servers.net server so that interested organisations may understand the general intentions and requirements of this phase of the project. Organisations wishing to express their interest in supporting this important activity may do so by following the guidelines below. Physical Sites -------------- Suitable sites for the location of mirror instances of the k.root-servers.net server will in most cases include an Internet exchange (IX) that offers a very high standard of infrastructure and Internet connectivity. The members of the IX should represent a significant ISP community in the region. In terms of physical infrastructure and services, a hosting site must satisfy the general requirements for root server locations, which are described in section 3.1 of RFC2870. Server Hardware --------------- All hardware for the instance of k.root-servers.net will be supplied at the host's expense. In most cases a typical configuration will be assembled by the RIPE NCC and shipped to the hosting site. The hardware will remain the property of the host, but will be operated solely by the RIPE NCC. The host will be asked to provide onsite physical support. However there is no requirement for the host to perform maintenance on the systems themselves, and administrative access will not be available. Connectivity and reachability ----------------------------- Though global reachability is not required for the instance of the k.root-servers.net server, it is critical that access to the server is provided in an open and non-discriminative manner to all members of the IX. However, it is important that global transit is co-ordinated with the RIPE NCC. Requirements for reachability are different for the management network of k.root-servers.net that is used by the RIPE NCC to perform system administration. It is required that connectivity of the management network is global and reliable. Expressions of Interest ----------------------- The RIPE NCC invites expressions of interest from organisations such as Internet Exchanges or other organisations that represent a significant ISP community in the region. Expressions of Interest should include details of the support which is being offered, such as hosting and connectivity. Please provide as much detail as possible, including physical infrastructure details, upstream and peer network connectivity details, and bandwidth availability. Please refer specifically to the provisions of RFC2870 in your response. Please send expressions of interest to: k-anycast(a)ripe.net If any further information is required, please also use this address.
