Dear SIG members,
A new version of the proposal "prop-141-v002: Change maximum delegation
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.
https://conference.apnic.net/52/program/schedule/#/day/4
We invite you to review and comment on the proposal on the mailing
list before the OPM.
The comment period on the mailing list before the OPM is an important
part of the Policy Development Process (PDP). We encourage you to
express your views on the proposal:
- Do you support or oppose this proposal?
- Does this proposal solve a problem you are experiencing? If so,
tell the community about your situation.
- Do you see any disadvantages in this proposal?
- Is there anything in the proposal that is not clear?
- What changes could be made to this proposal to make it more effective?

prop-141-v002: Change maximum delegation size of IPv4 address from 512 ( /23 )
to 768 (/23+/24) addresses.
-----------------------------------------------------------------------------------------------------------
Proposer: Simon Sohel Baroi (sba...@gmail.com)

1. Problem statement
--------------------
According to the APNIC IPv4 Address
Report,(https://www.apnic.net/manage-ip/ipv4-exhaustion/ ) 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.
