Under this proposal, APNIC would reserve the appropriately sized IPv6
block for each APNIC member that has IPv4 addresses but does not yet
have IPv6 addresses.
I have an issue with 'reserving' based on member's current v4 address
allocation. This assumes that the companies will remain static, will
not
request (or acquire) more v4 addresses before they actually deploy v6.
Also, I have an implementation question on this though. How does the
reserving of address space work with the binary chop/ sparse
allocation
practiced by APNIC currently.
For example, if someone has a v4 allocation currently, and are
assigned
a /32, but say in 2 years time when they are actually ready to request
for v6, they may need a /30. how does the reserved address work in
this
case ? If the secretariat has to actually do any work to change the
'reserved' allocation to a 'regular' allocation, it's still double the
work, and would not achieve much.
