Re: [Wg-ipv6-guide] (ToC-9) Subsequent Allocations

Dear Nakagawa-san and all,


Thanks for providing us with the basis for discussion.

I have listed a few points which I thought may be helpful to describe
in this section:

 - /48 assignments must be registered in the registry database to be
   considered utilized. If no registration are made in the database,
   it will not be considered utilized regardless of the actual
   operation

 - If a sub-allocation is made to a down stream ISP, but not
   assignments are registered in the database, it will not considered
   utilized
   e.g.) /40 sub-allocation is made to a downstream ISP. 2*/48 is
         assigned from this block. In this case, 2*/48 is considered
         as utilized, not /40(256*/48).

 - a /48 can be assigned per POP as well per "site"

 - It may be helpful to add a specific example such as:
    The following case is eligible for the 1st subsequent allocation
    since it has registered 7,132 * /48s assignments

    assignments to POPs                   326 * /48
    assignments to sites                6,500 * /48
    assignments through downstream ISP    306 * /48
    ------------------------------------------------
    total                               7,132 * /48s 

 - It's a really minor point, but it could be misleading to call the
   1st subsequent allocation "Initial allocation". Some people may
   think you are refering to the actual initial allocation.

Also, this should probably go into the initial allocation section, but
let me comment on one point which came up to my mind.

It may be worth noting that at the time of the initial allocation
request, sub-allocations to downstream ISPs are taken into account as
"to be assigned /48".

e.g) The following case meets the initial allocation criteria of
     200*/48

     Plan within the next two years:
     /44 sub-allocation   (= 16*/48 assignments)
     assignments to POPs     20*/48
     assignments to "sites" 170*/48 
     ------------------------------------------------------------
     total                  206*/48  > 200*/48 


Thanks, and I welcome any feedbacks!

Best Regards,
Izumi
