In the context of the above I have some additional data that we have extracted from the database. As the wider audience may be aware, the 'rev-srv' attribute in the inetnum (and inet6num) objects is the rather early predecessor of using the 'domain' object and its 'nserver' attributes to represent a reverse delegation. The 'rev-srv' attribute, while it has never been depreciated and is not used as a source for authoritative DNS data, is still able to be used as an informational attribute. For purposes of this discussion, I've compared the contents of the inetnum 'rev-srv' attribute with the domain 'nserver' attribute. For the comparison I also introduce the concept of 'derived delegation'. A 'derived delegation' is essentially working out which 'in-addr.arpa' delegation would best match the inetnum. Effectively, a /15 inetnum becomes two /16-level 'derived delegations', and a /17 inetnum becomes 128 /24-level 'derived delegations'. First the data for reverse delegation information in inetnum objects. Total number of inetnum objects: 879691 Total number of inetnum objects with rev-srv: 54921 (6%) Total number of derived delegations: 27804 (3%) The fact that the number of derived delegations is smaller than the number of objects with rev-srv attributes is accounted for by inetnums which either cover very large ranges (/8 and greater) or smaller ranges (/25 and lesser) which we do not delegate directly. Secondly, the data for reverse delegation information in domain objects. Total number of domain objects: 113153 Total number of valid reverse domain objects: 105785 A valid reverse domain object is one that makes sense within the DNS; it has a set of nservers, and refers to a possible delegation (ie, its within in-addr.arpa and has numbers between 0 and 255). Comparing the two sets of delegation information. Total number of domain objects that do NOT match any derived delegation: 95051 Total number of derived delegations that do NOT match any domain object: 16523 Total number of matches between derived delegations and domain object: 18011 The number of domain objects is larger as the NCC has been using them to represent authoritative reverse delegations during the recent (6 years?) growth period of the internet. The number of derived delegations without a matching domain object is non-zero for two reasons; The statistics script has calculated the 'best' delegation possible, and hasn't taken into account the possibility of a /16 inetnum being delegated to 255 /24-level domain objects (etc), or there are old inetnums which had their corresponding delegations created before the current system of using domain objects. We now compare the 18,011 domain objects that have a matching derived delegation, and cross checking the NS sets (as are intended to be published in the DNS) of each. Total number of mismatches in NS sets: 10734 Total number of exact matches in NS sets: 7277 In summary; - rev-srv attributes are used infrequently at the moment, and the information within them has a low accuracy. - There would be a large cleanup of inetnum objects required to ensure that the rev-srv attributes matched the delegations in the domain objects, and thus be usable for the creation of authoritative DNS delegations. - In the current proposal effort is needed to make sure that "legacy" reverse delegations that do exist in the DNS, have a corresponding rev-srv attribute, but do not have a DOMAIN object in the database, get fixed. -- Bruce Campbell RIPE Systems/Network Engineer NCC www.ripe.net - PGP562C8B1B Operations/Security

ripe rejecting "valid" e-mail
by Peter Galbavy 08 Oct '03

08 Oct '03

I replied, in all innocence, to the recent e-mail from NCC about the change to allocation objects - commenting on how an LIR like me cannot actually update the object themselves. Don't point me to the LIR portal - without a working fax number I cannot get an account. Been there, done that. Anyhow, I get back: -- quote -- The RIPE-NCC hostmaster distribution robot has extracted the following additional information from it: RegID: No valid RegId found Ticket Number: NCC#2003101214 We will NOT handle this message. It is of type NOREGIDBOUNCE. It concerns an ongoing request. -- ... -- Er, when you have a valid ticket number *why the hell* do you need a regID as well ??? Some people really have too much spare time and write too much code that doesn't consider the real world. Anyone else object to the over-babying of inbound mail to the NCC ? The prices stay high, the work they are willing to do goes down. As usual. Peter

RIPE 46 Meeting Report
by Nick Hyrka 02 Oct '03

02 Oct '03

(Apologies for duplicate mails.) RIPE 46 Meeting Report Dear Colleagues: The RIPE 46 Meeting was held from 1 - 5 September 2003 at the Grand Hotel Krasnapolsky, Amsterdam, the Netherlands. There were a total of 307 attendees comprised of the RIPE NCC membership, the RIPE community and government representatives. Attendees also included representatives from APNIC, ARIN, AfriNIC, LACNIC and ICANN. HIGHLIGHTS ========== Highlights of RIPE 46 included the open discussion on the services of the RIPE NCC during the first session of the RIPE NCC Services Working Group; a presentation on current RIPE NCC services and plans for 2004 by Axel Pawlik, Managing Director, RIPE NCC; an AfriNIC update; and an update on the changes to Test Traffic Measurement. The European Operators Forum (EOF) featured a full-day tutorial on Voice over Internet Protocol (VoIP) and ENUM that included an overview of current technologies and a focus on practical deployment aspects such as gateways, security, provisioning and use of the new ENUM standards. Geoff Huston, Telstra, gave a presentation on IPv4 Address Lifetime Expectancy. The RIPE NCC would like to thank SURFnet, BIT, FLAG Telecom and KPN EuroRings for the support they provided to the meeting. SUMMARY ======== ADDRESS POLICY ============== - Hans Petter Holen, Chair, requested community involvement to help revise ripe-152 ("Charging by Local Internet Registries") if necessary. - The RIPE NCC will resubmit the IPv4 policy document for community review. - There was a discussion on PI/PA issues and whether the distinction is still valid. - It was agreed that a more formal process was needed for the policy development process. Address Policy Working Group presentations can be viewed at: http://www.ripe.net/ripe/meetings/ripe-46/presentations/#ap DATABASE ======== - Wilfried Woeber, Chair, will co-ordinate with the RIPE NCC to prepare a document summarising the basic assumptions about the use of the RIPE Database. - "status:" attribute values will change. Current efforts aim at consistency between the RIRs and having easy to understand values. - The organisation object proposal received positive feedback from the working group, with suggestions for other features. - The RIPE NCC will implement X.509 authentication before the next RIPE Meeting. Database Working Group presentations can be viewed at: http://www.ripe.net/ripe/meetings/ripe-46/presentations/#db TEST TRAFFIC MEASUREMENTS (TTM) ========================= - As of 1/1/2004 changes will be made to the TTM service contract: Fees will be lowered, all data will be made public with lightweight Acceptable Use Policy (AUP). - Bandwidth measurements: tests showed that results are not conclusive enough so the TTM service will wait before delivering this new product. TTM Working Group presentations can be viewed at: http://www.ripe.net/ripe/meetings/ripe-46/presentations/#tt ANTI-SPAM ========= - Rodney Tillotson, Chair, will post a proposal to the Anti-Spam mailing list regarding methods to improve finding abuse contacts in the RIPE Database. Anti-Spam Working Group presentations can be viewed at: http://www.ripe.net/ripe/meetings/ripe-46/presentations/#anti-spam IPv6 === - The 6BONE phase-out was discussed. The next milestone will be 01/01/2004 when new allocations stop. - Discussion on the separation of the identifier and locater functions of IP addresses in regards to IPv6 multihoming. IPv6 Working Group presentations can be viewed at: http://www.ripe.net/ripe/meetings/ripe-46/presentations/#ipv6 TECHSEC ======== - Community feedback was requested on the requirements needed to secure large scale IP infrastructure especially around CLI interface requirements. - The RIPE NCC presented a report on DNSSec status, DISI achievements since RIPE 45 and the impact of signing on zone size. - George Jones, Mitre, gave a presentation on operational security requirements including the history and current status of the requirements, related work, next steps and milestones. - Baiba Kaskina, TERENA, gave a presentation on Euro CSIRT developments that included details on the CSIRT Task Force, the countries involved, the projects and deliverables. - NLNetLab presented an update on Fonkey and PKI-related developments in IETF. TechSec Working Group presentations can be viewed at: http://www.ripe.net/ripe/meetings/ripe-46/presentations/#techsec EIX == - Support was expressed for aligning and harmonising IPv6 address space policy regarding IXPs with other RIRs and existing IPv4 policies. - Reports were presented by 11 European IXPs in Europe that showed a trend of steady growth, use of GE instead of FE and wide deployment of IPv6. - Discussion of the Inter-Provider Traffic Analyzer that uses past data and statistical calculations to detect anomalies in traffic patterns. - EIX presentations were given on the anycast deployments of the "F" and "K" root servers by ISC and the RIPE NCC. EIX Working Group presentations can be viewed at: http://www.ripe.net/ripe/meetings/ripe-46/presentations/#eix DN* === - From the merging of the former DNS Working Group and DNR Forum it was concluded that one working group is sufficient to deal with everything related to Domain Names. A new name/charter will be discussed on the mailing list. - Jaap Akkerhuis, DN* Co-Chair, will organise a "DNS Related Issues" document. - Peter Koch, DN* Co-Chair, talked about how firewall vendors could make mistakes handling DNS communication issues. DN* Working Group presentations can be viewed at: http://www.ripe.net/ripe/meetings/ripe-46/presentations/#dn RIPE NCC SERVICES ================ - Axel Pawlik noted that the RIPE NCC will present more details in next year's RIPE NCC budget. - There were comments on the current RIPE NCC services, whether they benefit the entire community and whether a 'pay per service' system could be an option. - There was discussion about the need for a more transparent evaluation of RIPE NCC activities and how they benefit the community. RIPE NCC Services Working Group presentations can be viewed at: http://www.ripe.net/ripe/meetings/ripe-46/presentations/#ncc TUTORIALS ========= - The RIPE NCC staff presented the RIPE NCC IP Request Tutorial. It explained address space assignment and allocation procedures in the RIPE NCC region: http://www.ripe.net/ripe/meetings/ripe-46/tutorials/ip-request/ - A full-day tutorial on VoIP and ENUM was presented during the European Operators Forum (EOF). For more information about the EOF at RIPE 46 see: http://www.ripe.net/ripe/meetings/ripe-46/eof.html RIPE MEETING WEBCASTING ======================= - The third phase of RIPE Meeting webcasting trials was held at RIPE 46. Recordings of certain sessions from RIPE 46, including the Plenary, have been archived and can be accessed at: http://www.ripe.net/ripe/meetings/ripe-46/webcast.html HOSTMASTER CONSULTATION CENTRE (HCC) ==================================== - The RIPE NCC Hostmaster Consultation Centre was open at RIPE 46, allowing RIPE NCC Members to discuss issues relating to their business directly with RIPE NCC Hostmasters.

Hi, #3) "Routeviews project now has a test/static asn zone up that you can try" # # % dig @archive.routeviews.org 13.142.223.128.asn.routeviews.org txt # # comments: interesting idea but at the time it was still under # development. It's a production service now, and gets rebuilt and reloaded twice a day; DMM announced it on NANOG, for example. The comment was also offered: # strange replies on non-matched IPs, e.g. try # host -t txt 7.227.290.195.asn.routeviews.org Zen-like question: for dotted quads not in the routing table, what *should* be returned? One postulated answer: 4294967295 ==> "route not in table" You could pick some other "magic" number, but I think this one should serve the purpose just fine. :-) Regarding the other ip2asn methods, I'm happy having a thousand methods bloom, so long as they enhance the ability of folks to tie dotted quads to a relevant responsible entity. :-) Regards, Joe P.S. Also note that in addition to the asn zone, an aspath zone is also available, provided in part to deal with any attempt to interpose "throw away" stub ASNs to shelter "real" ASNs; it is available by querying host -t txt $revip.aspath.routeviews.org Be sure to anticipate and plan for the possibility of multiple aspath txt records being returned in response to a query.
