    First explicit stance: Unknown → Latest explicit stance: Unknown · Stance changes: 0

    Viewpoint consistency: Insufficient evidence to assess consistency

    The sole retained observation is a meeting summary that records group consensus outcomes for four proposals. It does not provide Toshiyuki Hosaka’s own positions or a second statement, so it cannot establish longitudinal or cross-policy viewpoint consistency for these records.

    A proposal to prevent the routing of “dark” address space

    Assessment: Insufficient evidence to assess consistency · The message reports that the dark-address-space proposal did not reach consensus. It is a meeting summary and does not establish Toshiyuki Hosaka’s own position; one record cannot establish consistency or a change over time.

    Conditions: The record reports a group or process outcome and does not establish the participant’s personal support, opposition, adoption, or implementation view.

    - Consensus was not reached.

    Application of the HD ratio to IPv4

    Assessment: Insufficient evidence to assess consistency · The message reports no clear consensus on applying the HD ratio to IPv4 and says the proposal should remain open. This is a process summary rather than a stated personal position, and one record cannot establish consistency or a change over time.

    Conditions: The record reports a group or process outcome and does not establish the participant’s personal support, opposition, adoption, or implementation view.

    - There was no clear consensus.

    Expansion of the initial allocation space for existing IPv6 address spaceholders

    Assessment: Insufficient evidence to assess consistency · The message reports that the proposal to expand initial IPv6 allocations reached consensus. The report does not state Toshiyuki Hosaka’s own view, so one record cannot establish consistency or a change over time.

    Conditions: The record reports a group or process outcome and does not establish the participant’s personal support, opposition, adoption, or implementation view.

    - Consensus was reached.

    Internet Assigned Numbers Authority (IANA) policy for allocation of IPv6blocks to Regional InternetRegistries Adopted by all RIRs

    Assessment: Insufficient evidence to assess consistency · The message reports consensus on the revised IANA IPv6 allocation policy with parameter flexibility. This is a meeting outcome reported by the co-chair, not a substantiated personal position, and one record cannot establish consistency or a change over time.

    Conditions: The record reports a group or process outcome and does not establish the participant’s personal support, opposition, adoption, or implementation view.

    - Consensus reached for the revised proposal, with some flexibility of parameters. Flexibility is left for consensus of other regions

    A proposal to prevent the routing of “dark” address space · Expansion of the initial allocation space for existing IPv6 address spaceholders

    Assessment: Insufficient evidence to assess consistency · The summary reports different group outcomes for two proposals, but it does not provide Toshiyuki Hosaka’s own positions on either proposal. The comparison therefore cannot establish a cross-policy consistency or inconsistency finding.

    Conditions: The comparison concerns reported group outcomes, not a verified personal viewpoint.

    - Consensus was not reached.

    - Consensus was reached.

    1. Sep 9, 2004 · Procedural or neutral

      [sig-policy] Summary report of APNIC 18 Policy-SIG

      (3) prop-021-v001: Expansion of the initial allocation space for existing IPv6 address space holders - Proposal summary: To expand IPv6 address space for existing IPv6 address holders without satisfying the subsequent allocation requirements, with IPv6 deployment plan and/or with IPv4 infrastructure information. - Consensus was reached.
