Re: [sig-policy] Prop-127 announcement : Change maximum delegation size of 103/8 IPv4 address, pool to a /23

["Md. Abdul Awal" <awal.ece@gmail.com>]

I partially support this proposal.

While minimizing the delegation size from /22 to /23 would delay the IPv4 exhaustion in this region, this discussion would return again later on with proposals like minimizing the delegation size to /24. It'd be interesting to see how community reacts to this.

prop-127-v001: Change maximum delegation size of 103/8 IPv4 address
pool to a /23

1. Problem Statement

This is a proposal to change the maximum size of IPv4 address delegations
from the APNIC 103/8 IPv4 address pool [1] to a /23.

2. Objective of policy change

The current final /8 allocation policy[1] requires that the current minimum
delegation size for IPv4 is a /24 and each APNIC account holder is only
eligible
to receive IPv4 address delegations totalling a maximum /22 from the
APNIC 103/8
IPv4 address pool.

According to the APNIC IPv4 Address Report, https://ipv4.potaroo.net/,
remaining
addresses in the APNIC 103/8 pool are 42.8%, 33.3%, 23.4% of /8 in the
end of
2016, 2017, and 2018, respectively. The remaining number of APNIC 103/8
IPv4
address pool for APNIC account holder is less and less. It is predicted
that
the 103/8 pool will be exhausted in 2020.

Reducing the maximum IPv4 delegation size from APNIC 103/8 IPv4 address
pool can
prolong the exhaustion time of the 103/8. Newcomers of APNIC account
holders will
have the benefit in this period of time. New companies can obtain some
IPv4 address
space in the APNIC service region without the need to trade for address
space and
can make the preparation for the subsequent IPv6 migration.

It is recommended that the number of assigned IPv4 addresses in Final /8
be reduced
from a maximum of /22 to /23. It will be estimated to extend the
exhaustion time
for at least three years or more.

3. Situation in other regions

There is no similar policy in place in other RIR regions.

4. Proposed policy solution

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

This proposal is to change the maximum size of IPv4 address delegations
from the
APNIC 103/8 IPv4 address pool[1] to a /23. /23 is important because new
ISPs can
use /24 for internal infrastructure and /24 customer assignments and NAT
for IPv6
transition.

Current Policy text

Each APNIC account holder is only eligible to receive IPv4 address
delegations
totalling a maximum /22 from the APNIC 103/8 IPv4 address pool.

New Policy text

Each APNIC account holder without APNIC 103/8 IPv4 address delegations
from the
APNIC 103/8 IPv4 address pool is only eligible to receive a maximum /23
from the
APNIC 103/8 IPv4 address pool.

5. Advantages / Disadvantages

Advantages:
- This proposal allows a greater range of networks to access the
resources in
the final /8.

• This proposal extends the maximum possible total number of networks that can benefit from the final /8 pool from around 16,000 to around 18,000 networks, providing small amounts of IPv4 to be available for networks, developing economy, etc., making the transition to IPv6 for many years to come.

Disadvantages:
- No disadvantages are foreseen.

6. Impact on resource holders

It reduces the maximum size of the delegated address block available to
APNIC
members during the final /8 phase. This will affect NIR members in the
same way
as APNIC members.
