Abstract

    This document discusses the need for delegation of the
    E.F.F.3.IP6.ARPA DNS zone in order to enable reverse lookups for
    6bone addresses.

. 6bone and DNS

    The 6bone, whose address space was allocated by [RFC2471], has
    provided a network for IPv6 experimentation for numerous purposes for
    seven years.  Up to the present time, reverse lookups for 6bone
    addresses have been accomplished through IP6.INT.  It is now
    important that the thousands of 6bone users be able to update their
    IPv6 software to use IP6.ARPA.

    Although the 6bone has a limited life, as a phaseout plan is being
    discussed at the IETF at this time [I-D.fink-6bone-phaseout], there
    is likely to be 2.5 to 3.5 more years of operation. During this
    remaining 6bone lifetime IP6.ARPA reverse lookup services for the
    3ffe::/16 address space are required.

    Discussions have been underway between the 6bone and RIR communities,
    about having the RIRs perform this service.  It was agreed at the San
    Francisco IETF meeting that it was more practical for the 6bone to
    provide this service for itself. This would relieve the RIRs of the
    costs of providing this service, yet still provide the IP6.ARPA
    authority the ability to terminate the service when the planned 6bone
    termination date is reached (currently anticipated to be June 6,
    2006).

    The current planning within the 6bone operational community is to
    provide new inet6num attributes in the 6bone registry database for
    top level 6bone address space holders to request delegation to their
    reverse path servers.

. IANA Considerations

    This memo requests that the IANA delegate the E.F.F.3.IP6.ARPA domain
    to the 6bone as will be described in instructions to be provided by
    the IAB.  Names within this zone are to be further delegated within
    the top level 6bone ISPs (known as pTLAs) in accordance with the
    delegation of 6bone 3FFE::/16 address space.

. Security Considerations

    While DNS spoofing of address to name mapping has been exploited in
    IPv4, delegation of the E.F.F.3.IP6.ARPA zone creates no new threats
    to the security of the internet.
