Hi Vivek,

We would like some clarification on the following two points as they are not consistent.

> Increasing the maximum IPv4 delegation size from /23 to /23+/24 IPv4 address pool will allow Newcomers and also
> Existing APNIC account holders who only received /23 after Thursday, 28 February 2019 to receive 256 (/24) IPv4
> addresses.

The above point suggests regardless when an organization became an APNIC member, if they only received /23 after Thursday, 28 February 2019, they will be eligible to receive an additional /24.
What happens if an account holder had only received a /24 before Thursday, 28 February 2019? Would they be excluded from receiving this additional delegation?

Anyone who became a member after 28th February 2019 was only eligible for a maximum of /23. So anyone who received /23 after 28th Feb is eligible for extra /24. Anyone who only received /24 after 28th Feb is eligible for /23 (/24 as per existing policy and /24 from this proposed policy).

> The Organization who became an APNIC member after Thursday, 28 February 2019 and received only /23, can receive
> another /24 IPv4 Resources.

The above point suggests that only those organizations who became an APNIC member after Thursday, 28 February 2019 are eligible for this additional delegation.

I understand your point, this statement not only applicable to members who were impacted by the change of policy from /22 to /23 on 28th Feb 2019 but Any member who only received /23 or /24 under previous policy (max delegation size of /22 or before that), who had the opportunity to receive up to /22 and they either never asked for it or were not eligible that time can still apply for extra IPv4 addresses. This Is because we are suggesting to increase the maximum delegation size from /23 (512 IPv4 addresses) to /23 + /24 (768 IPv4 addresses), we have submitted the updated the text without any date reference to make sure there is no confusion.

Thanks
Vivek

size of IPv4 address from 512 ( /23 ) to 768 (/23+/24) addresses" has
been sent to the Policy SIG for review.

It will be presented at the Open Policy Meeting (OPM) at APNIC 52
on Thursday, 16 September 2021.

We invite you to review and comment on the proposal on the mailing
list before the OPM.

prop-141-v002: Change maximum delegation size of IPv4 address from 512 (
/23 ) to 768 (/23+/24) addresses.

-----------------------------------------------------------------------------------------------------------

Proposer: Simon Sohel Baroi (sbaroi@gmail.com)
Aftab Siddiqui (aftab.siddiqui@gmail.com)

1. Problem statement
--------------------
According to the APNIC IPv4 Address
Report,(https://aus01.safelinks.protection.outlook.com/?url=""> ) the available
and reserve pool size is as follows:

Available Pool : IP Address 3,782,144 | 14,774 Of /24
Reserved Pool : IP Address 1,831,680 | 7,155 Of /24

If APNIC continues to delegate IPv4 in size of /23 with the average
growth rate of 145 x /23 delegations per
month the pool will be exhausted around Aug/Sep 2027. Which means the
huge number of IPv4 addresses will be
unused for a long time and large community members will still remain
behind the NAT box or without Internet
Connectivity.

2. Objective of policy change
-----------------------------
The current final /8 allocation policy [1] advise that the current
minimum delegation size for IPv4 is 256 (/24)
addresses and each APNIC account holder is only eligible to receive IPv4
address delegations totaling a maximum
512 (/23) addresses from the APNIC 103/8 IPv4 address pool. (6.1.
Minimum and maximum IPv4 delegations)

This is a proposal to change the maximum size of IPv4 address
delegations from the available IPv4 address pool to
a totaling of 768 (/23+/24) addresses. This proposal also indicates how
APNIC will distribute the IPv4 resources
systematically when the available pool size reduces.

Increasing the maximum IPv4 delegation size from /23 to /23+/24 IPv4
address pool will allow Newcomers and also
Existing APNIC account holders who only received /23 after Thursday, 28
February 2019 to receive 256 (/24) IPv4
addresses.

3. Situation in other regions
-----------------------------
There is no similar policy in place in other RIR regions.

4. Proposed policy solution
---------------------------
It is recommended to increase the IPv4 address delegation size from 512
max (/23) to 768 (/23 + /24). The address
space can now be allocated from the available 103/8 last /8 block and/or
from non 103/8 recovered address blocks.
This policy will continue until the available + reserved comes down to
less than 900,000 IPv4 addresses i.e.
< 3515x/24, once reaching this threshold the maximum delegation size
will revert back to 512 IPv4 addresses (/23)
and will continue to do so until the available + reserved block comes
down to 256,000 IPv4 addresses i.e 1000x/24
then the delegation size will further reduce to 256 IPv4 addresses i.e.
/24. The very first time the reserved and
available pool goes below 190,000 IPv4 addresses then the IPv4 reserved
pool (APNIC-127 Section 5.1.1) for Future
Use of /16 (i.e. 256 x /24s) will be added to the available pool.

Thresholds for IPv4 addresses (Available + Reserved):

- More than 900,000 IPv4 addresses: Delegation /23 + /24
- Less than 900,000 IPv4 addresses AND More than 256,000 IPv4 addresses:
Delegation /23
- Less than 256,000 IPv4 addresses: Delegation /24
- Less than 190,000 IPv4 addresses - add APNIC-127 5.1.1 Reserved /16 to
available pool: Delegation /24

It is proposed to modify the section 6.1 maximum IPv4 delegations of the
APNIC Internet Number Resource Policies
[1] accordingly.

Current Policy text :

Since Thursday, 28 February 2019, each APNIC account holder is only
eligible to receive IPv4 address delegations
totalling a maximum /23 from the APNIC 103/8 IPv4 address pool.

New Policy text :

New APNIC account holder is only eligible to receive IPv4 address
delegations totaling a maximum 768 (/23+/24) from
the APNIC available IPv4 address pool.

Existing APNIC account holders (since Thursday, 28 February 2019), who
only have /23 can apply for another /24 maintaining
the criteria matched with section 7.0.

If the available IPv4 Pool size, which consists of available and reserve
pool goes below 900,000 addresses (3515, /24s
after last delegation), the delegation size will automatically become
512 (/23) IPv4 addresses.

If the available IPv4 Pool size, which consists of available and
reserve, reaches 256,000 IPv4 addresses (i.e. 1000 /24s
after last delegation), the delegation size will be reduced to 256 (/24)
IPv4 addresses. The very first time the reserved
and available pool goes below 190,000 IPv4 addresses then the IPv4
reserved pool of /16 (256 /24s) will be added to the
available pool (APNIC-127 Section 5.1.1).

At any point, if APNIC receives a large block of recovered/returned/etc
IPv4 address space increasing the total available
address space and moved into the previous threshold then the delegation
size will revert back to previous delegation size
as well. Also, all delegations at this stage have to be made
retrospectively i.e. any member who received smaller delegation
size will be eligible to receive more IPv4 addresses as per this policy,
based on their usage criteria matched with
section 7.0 and availability of addresses.

5. Advantages / Disadvantages
-----------------------------
Advantages:
- This proposal will ensure smooth allocation of IPv4 addresses to
existing and new APNIC members.

Disadvantages:
- This might add up to 10,000 /24s into the global routing table i.e.
1.2% increase. The current growth rate without this
policy is approximately 7% every year.

6. Impact on resource holders
-----------------------------
The Organization who became an APNIC member after Thursday, 28 February
2019 and received only /23, can receive another
/24 IPv4 Resources.
