Dear Yong Wan Ju,
Thank you for an advice.
> Did you consider CAP policy to describe the last description in this mail ?
I didn't consider it and I learned it yesterday. I should delete it.
Some ISPs or people might be misunderstanding like me, so I suggest to
add it as follows.
In addition, I added the definition how to count the allocated/assigned blocks
as follows.
Is is written in "Policy - 5.5 Registration", but few people see 5.5
when they need info about subsequent allocation (probably).
So I suggest to describe it in this clause.
Best regards,
Akira

9 Subsequent Allocations
An example of a typical ISP.
(1) Initial allocation
A typical ISP receives /32 that is 65,536 * /48s as an initial
allocation.
If this ISP allocates or assigns 7,132 * /48s to it's customers and
its POPs, this ISP has a right of the second ( subsequent )
allocation.
7,132 is from the HD-Ratio table ( Appendix A )
(2) Second allocation
This ISP receives additional /32 from an adjacent address block as
the second allocation. Now, this ISP has one /31 address block.
If this ISP allocates or assigns 12,417 * /48s including the
previous 7,132 * /48s to it's customers and its POPs, this ISP has a
right of the third ( subsequent ) allocation.
12,417 is from the HD-Ratio table ( Appendix A )
### added from here
RIRs temporarily reserve 8 * /32 adjacent address blocks for each
organization. This space is worth /29. But unless each organization
obtains additional allocation, these spaces can be allocated to other
organizations based on the Space Allocation System.

The number of /48 blocks which each organization has allocated or
assigned is counted based on the database.
