  1. APNIC IPv6 status report

    2. George Kuo, APNIC

    This presentation gave an overview of APNIC's IPv6 allocation activity over the past six months, including the results of a 2006 IPv6 survey of the Asia Pacific region undertaken by APNIC.

    Questions and discussion

    • There was a question about who had been included in the IPv6 survey. The speaker noted that the survey had been sent to APNIC members who had held IPv6 address space for two years or more; NIRs had also been invited to pass on the survey questions to members who have held IPv6 space for more than two years.

    Action items

    • None.

  2. The phasing out of the 6bone

    3. Geoff Huston, APNIC

    This presentation examined the phase out of the 6bone network in June 2006 and its impact on the IPv6 routing table. The speaker noted a number of other anomalies in the IPv6 routing table, including the removal of ghost routes. The speaker noted that there are a small number of people still using 6bone prefixes.

    Questions and discussion

    • There was a question as to whether the 6bone phase out could be regarded as a success. The speaker noted that it could, except for the small number of stragglers. The speaker also noted the destruction of "ghost routes" in February of 2006, and that the remaining 6bone members could conceivably be ghost routes, though this was unlikely.
    • There was a comment that it was unclear what was responsible for the oscillations noted in the presentation. The speaker noted that the data showed eight prefixes that were oscillating approximately 80 times per second for several days.
    • There was a comment from Jordi Palet regarding the contention that no one was using the 6bone for transit. The commenter noted that Sprint had in fact been doing this, and was still using those addresses for transit. The commenter noted that his company was using filters to avoid 6bone prefixes. The commenter also noted the activities that had occurred around IPv6 Day on June 6, 2006.
    • A commenter noted that they could possibly contact one of the people identified as still being connected to the 6bone.

    Action items

    • None.

  3. IPv6 multi-prefix environment: concept, issues, and solutions

    4. Ken-ichi Kanayama, Intec NetCore

    The speaker discussed IPv6 multi-prefix environments (a network in which end-sites use two or more address prefixes), and some of the challenges involved in establishing and maintaining these environments. These environments provide reductions in cost, higher reliability and manageability, and encourage a new type of ASP.

    Questions and discussion

    • There was a comment that it is possible to use the technique described in a home environment, and it was asked why the speaker had excluded this possibility. The speaker noted that it may be possible, but the details had not been considered at this point.
    • The Chair noted that two of the problems described had been fixed, but questioned whether the DNS problem had been fixed, and if not, how this might be done. The speaker noted that research is currently underway on this question.
    • The Chair noted that while this may seem a theoretical problem for those outside Japan, the issue addressed in the presentation was already a serious problem for the Japanese industry.
    • There was a question regarding the tool discussed in the presentation, and whether it could only switch between two networks, or would support both networks concurrently. The speaker noted that it could support both options.
    • There was a comment noting that this may be related to the concept of multihoming in the PA environment.

    Action items

    • None.

  4. IPv6 PA multihoming

    5. Marla Azinger, ARIN

    This presentation looked at what solutions exist to enable IPv6 multihoming and traffic engineering, and what solutions might be found on a global scale. The speaker noted that various organisations, including the IETF and the RIRs, were being approached to have input into possible solutions. Possible solutions at this point include filtering on specific CIDR boundaries, an aggregation plan to allow a specific number of slices to occur, metro/regional assignment of IP address space, community codes which could tag prefixes used for multihoming, a published list of IPv6 blocks (maintained by the RIRs) used for multihoming, and SHIM6. The speaker encouraged the audience to contribute any suggestions that they might have.

    Questions and discussion

    • The Chair noted that there was discussion of portable address space being used. The speaker noted that large providers needed to offer multihoming to those customers who do not want portable space, but that it might form part of a solution.
    • It was asked why the IPv4 solution to multihoming could not be used. The speaker noted that this system is not broken, but that there had been no consensus on using this solution, and if it was to be adopted a CIDR boundary would have to be agreed upon globally. The commenter noted that most ISPs are currently just using the same practices as for IPv4.
    • People are invited to email the presenter with any further comments at marla.azinger@frontiercorp.com.

    Action items

    • None.

  5. IPv6 deployment status in Japan

    6. Nao Fukushima, IPv6 Promotion Council of Japan

    The speaker discussed the status of IPv6 deployment within Japan, including governmental activities, the IPv6 Deployment Field Trial, and various other projects. The speaker noted that IPv6 services are currently available in Japan for home and business users, though these services are still improving.

    Questions and discussion

    • The Chair noted the IPv6 Family Mart deployment described in Ken-ichi Kanayama's presentation would also fall under the scope of this presentation.

    Action items

    • None.

  6. IPv6 deployment strategies and status in Taiwan

    7. Hung Chang Lee, National IPv6 Deployment & Development Program

    The speaker discussed the deployment of IPv6 in Taiwan. The speaker noted the role of the NICI IPv6 Steering Committee, and that the construction and deployment of IPv6 in Taiwan is well underway, but will be further driven by the release of new IPv6 applications and products.

    Questions and discussion

    • The Chair noted that Japan imports many routers from Taiwan, many of which claim to be IPv6 ready, but that this is often only true in bridge mode.

    Action items

    • None.
