Chris,

I'm not sure I understand your why not a /24 comment... can you clarify?

|An applicant may provide ARIN with a thirty-month forecast of IPv4 
|address need. ... When a reservation forecast is approved by ARIN, the 
|applicant will then be authorized to draw down from the forecast 
|quarterly. 

Are you saying:

1. A customer with ten 3-month quarters (30 months) with a documented need 
of ten /24s should be able to reserve either:
 A] one /21 and one /23 
 B] one  /21 (rounded down to the nearest CIDR)
 C] one /20  (rounded up to the nearest CIDR)

This customer could then attempt to justify and draw down one /24 every 3 
months.


2. A customer with a 30 month documented need for one /24 should be able 
to reserve one /24.

This customer could then attempt to justify and draw down either:
 A] one /28 every 3 months for the first year 
    and a /27 every 3 months for the last 1.5 years
    (or some similar combination of the same number of /28s and /27s)
 
 B] one /28 every 3 months (allowing the extra six /28s for rounding up)

3. A customer with a 24 month documented need for one /24 should be able
to reserve one /24.

This customer could then attempt to justify and draw down one /27 every 3 
months (shortening their draw down to two years due to rounding down)


4. A customer with a 30 month documented need for one /24 should be able
to immediately draw down a single /24, but then get no additional 
transition space in the next 30 months.

Maybe 32 months would be a more round number?  Thats is 2^5 months.  
Unfortunately that would give use 10 quarters (3 month periods) and one 
two month period at the end.

The good news about having an email address that is twice as long is that
it increases traffic on the Internet.

|I fixed your post - pp109 is about WHOIS and resource reservation,
|pp116 is about the reservation of IPv4.

|Why not a /24 minimum?
