Re: [sig-policy] prop-111-v001: Request-based expansion of IPv6 default
Hi Owen,
I'm sorry but I misread your commmet.

| ranging from /28 to /32 with encouragement towards either end (/28 or /32).
As Guangliang wrote in his mail, only /29 is reserved for
organizations in earlyer allcation address block. Main purpose of this
policy intend to utilize those address, which will be kept unused.
Yorus Sincerely,

|
| This has several advantages:
|
| 1. It reduces bitmath requirements.
| 2. It simplifies DNS delegation for ip6.arpa zones
| 3. It allows providers that simply don't need a larger allocation to choose the
| size that best meets their needs.
| 4. It simplifies APNIC's resource management process.
| 5. It simplifies the request process and qualification requirements.
