Introduction

As global digital transformation continues to deepen, the fair distribution and technical evolution of Internet number resources (IP addresses) remain at the core of concern for the Asia Pacific Internet community.

At the recent APNIC 61 Conference held in Jakarta, the Policy Special Interest Group (Policy SIG) engaged in in-depth debate on two significant proposals. These proposals addressed IPv6 allocation efficiency and the final allocation principles for remaining IPv4 resources.

For Taiwan’s telecommunications operators, small and medium-sized ISPs, and enterprise users, the discussions carry substantial practical and strategic relevance.

Issue 1: Flexibility in IPv6 Allocation Size — Efficiency vs. Fragmentation (prop-164)

Historically, the recommended minimum IPv6 allocation size has been /32. However, proposal prop-164 suggests reducing the minimum allocation to /36 (aligned on a hexadecimal nibble boundary).

Core Objective

The proposal aims to allow smaller operators to request address space based on actual needs, thereby avoiding “over-allocation” that may result in discrepancies between Whois database records and real-world utilization.

Community Debate

Supporters: Smaller operators argue that this approach would improve resource management precision and reduce operational and maintenance overhead.
Opponents: Many experts, drawing on European experience, caution that smaller initial allocations (such as /36 or /40) may lead to significant route fragmentation once networks expand to millions of users. Such fragmentation increases aggregation complexity and reduces routing efficiency.

TWNIC Observation

For Taiwan’s SMEs undergoing digital transformation, a /36 allocation may appear attractive. However, from a long-term scalability and international routing best-practice perspective, /32 remains the preferred choice to ensure a clean and future-proof network architecture.

Issue 2: Extending the Life of Remaining IPv4 Resources and the Pressure of IPv6 Transition (prop-168)

Although IPv6 deployment is an inevitable trend, IPv4 remains a critical requirement in emerging markets and dual-stack environments. Proposal prop-168 explores whether the maximum IPv4 allocation per account holder should be increased to /22.

Key Elements of the Proposal

1. Assisting new entrants in obtaining sufficient IPv4 space to support initial business operations.

2. Reserving a /12 address pool specifically for IPv4-to-IPv6 transition technologies (such as CGNAT).

3. Introducing a five-year transfer restriction period to prevent speculative behavior.

Focus of Debate

Community members expressed concern that relaxing IPv4 allocation limits might send the “wrong signal,” suggesting that IPv4 resources remain sufficiently available and thereby weakening incentives to accelerate IPv6 adoption.

Current Status

Due to the complexity of post-merger resource management considerations and the delicate balance between operational needs and transition incentives, consensus has not yet been reached. The proposal has returned to the mailing list for further discussion.

Participating in Policy Development: Why This Matters for Taiwan

APNIC policies are developed through a bottom-up, consensus-based process. During APNIC 61, the Policy 101 simulation exercise emphasized the importance of every community member’s voice in shaping policy outcomes.

For Taiwan, participating in these discussions is not merely about securing resources; it is about safeguarding our technical influence within the Asia Pacific region.

Whether regarding IPv4 resource fairness or IPv6 routing stability, these policy decisions directly affect the competitiveness of Taiwanese enterprises in the global Internet environment.

Conclusion

The discussions at APNIC 61 reflect a clear trend: Internet resource management is no longer about “allocating as much as requested,” but rather about optimizing deployment within finite resource constraints.

TWNIC will continue to monitor developments of these proposals on the mailing list and encourages domestic stakeholders to actively engage in the APNIC Policy Development Process (PDP).
