Here is my "try". Crude. Please send any comments and suggestions to make it better. izumi -------------- ALAC comment on IPv4 depletion and IPv6 migration We are aware that sometime within a few years time, current pool of IPv4 address will expire which may have significant impact on the use of Internet by broad public. Everyone agree the importance of making sure to allocate remaining pool of IPv4 address in a fair, equitable and predictable manner. The challenge here is what exactly we mean by "fair, equitable and predictable" that is pragmatic and implementable for all global users. We respect the policy works done by the RIRs so far, and are willing to actively participate more. We are concerned about the potential creation of "black market" and call for a rational ways to make secondary market a realty. We also call for a reasonable way of recollecting the unused IPv4 address blocks. We also like to call for more outreach work initiated by the ICANN community to make sure the issues are understood clearly and the solutions are communicated openly to broad public. We understand that the best solution to this challenge is to make smooth and orderly transition to the broad use of IPv6. There are several challenges and tasks to make that to happen: - Organize awareness campaign for the need for timely transition, - Avoid media hypes by providing accurate information to wider public - Make sure all "public sites" by governments and commercial service providers implement IPv4-v6 dual capacity in time - Measures be taken to help developing countries to prepare the transition in timely and affordable manner
