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, and makes specific recommendations for the process
needed to accomplish this.
1. 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 [RFC3152].
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 in March 2003 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.
2. 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.
3. 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.
