Japan Network Information Center (JPNIC) appreciates an
opportunity to comment on the issues shared as an open consultation by
Furthermore, it would allow more adequate inputs for the
issues from broad stakeholders to the Council Working Group if more information
is provided about the background of the issues raised for the consultation, as
well as how these inputs would be taken into considerations by the Council
Working Group. We would appreciate it if the Council Working Group could
consider sharing such information when making open consultations.
As a National Internet Registry managing the Internet
number resources in Japan, JPNIC would like to provide input on Issue 2:
Consultation on international public policy issues concerning IPv4 addresses.
We believe the issue concerning IPv4 addresses should be
discussed in the forums of Regional Internet Registries (RIRs), which are the
forums for the discussion on the management of IP address in an open,
transparent and bottom up manner. Raising issues and joining the discussions
are open to anyone, including governments, who is interested in the topic.
Regarding the management of legacy IPv4 addresses and
inter-region transfers of IPv4 addresses, both issues are adequately addressed
by the existing policies and practices of the RIRs. JPNIC co-ordinates and
adopts the policies and practices which are consistent with those of APNIC, the
RIR managing IP address space in the Asia Pacific region.
JPNIC adopts the following policies and practices:
(a) Unused legacy IPv4 addresses
JPNIC has signed a contract with all address holders
including legacy IPv4 addresses. This ensures that all legacy space
holders are correctly registered in JPNIC's registry database, so that the
holders, once they so wish, can transfer the space to another entity with a
demand for IPv4 addresses.
(b) Inter-region transfers of IPv4 addresses
adopted inter-registry IPv4 address transfer policy, which allows transfers of
IPv4 addresses with economies and regions outside of Japan.
These policies and practices are consistent with the
policies in the APNIC region as well as in the other RIRs, which has been
discussed in the open and transparent bottom up process and adopted by the
Since the emergence of the Internet, IP number resources
have been managed by RIRs and their predecessors with their policies and
practices formed through the due process which has involved the users, service
providers and other parties concerned with them. Especially, those for unused
legacy IPv4 addresses and Inter-region transfers of IPv4 addresses have been keenly discussed through RIRs'
policy forums with the largest ever interest and concern from the stakeholders.
It is truly important for all the stakeholders to have a good understanding
about the practices and the scheme of IPv4 address management which has enabled
the outcome described above, based on the reality of the situation. We are very
sure that new concerns and issues to be raised, based on such good
understanding, will be more than welcome in the RIR forums, as the constructive
discussions there will contribute to form better policies and practices which
address any future needs which have not been taken into considerations until
