Topic: IPv6-Only Transition in Vietnam: The 2026–2030 Program, the Role of IPv6 in National Digital Infrastructure, and Youth Actions

  1. Introduction

In Vietnam’s new era of national advancement, science, technology, innovation, and digital transformation have become key drivers of national development. In this spirit, Politburo Resolution No. 57-NQ/TW states that “the development of science, technology, innovation, and national digital transformation constitutes a foremost important breakthrough and serves as the primary driving force for the rapid development of modern productive forces" [1]. In order to achieve this goal, a contemporary, safe, and expandable Internet infrastructure is essential for guaranteeing connectivity, facilitating the use of digital services, and promoting the growth of the country's digital infrastructure.

However, IPv4's shortcomings in address space, scalability, and network management have become more apparent as the need for contemporary Internet infrastructure grows. Therefore, in order to increase address capacity, enhance connectivity, and guarantee the steady and long-term growth of the Internet in Vietnam, the switch to IPv6 has become essential. On this basis, Decision No. 3369/QD-BKHCN on the “Program to Promote, Deploy, and Transition to IPv6 Only in Vietnam for the 2026–2030 Period” was issued as a concrete step toward implementing the national policy on digital infrastructure development.

This essay focuses on analyzing the role of IPv6 in the development of Vietnam’s Internet infrastructure. It also proposes practical solutions and youth and student actions to help promote the IPv6 transition in connection with national digital transformation.

II. The 2026–2030 IPv6-Only Transition Program

  1. Background & Context

IPv6 is the essential infrastructure for the national digital transformation, provides the foundation for the development of digital government, digital economy, and digital society. Since 2021, Vietnam has recorded strong growth in IPv6 adoption and by October 2025, “Vietnam’s IPv6 adoption rate reached 65%, ranking 2nd in ASEAN and 7th in the world” [2]. On October 27, 2025, Vietnam’s Ministry of Science and Technology issued Decision No. 3369/QD-BKHCN approving the “Program to Promote, Deploy and Transition to IPv6 Only in Vietnam for the 2026–2030 Period” [3]. The program aims to transition the Internet in Vietnam to IPv6 only with IPv6 adoption reaching 90–100% by 2030 and IPv4 being phased out gradually [3]. According to Vietnam Internet Network Information Center (VNNIC), the program was developed in line with Resolution No. 57-NQ/TW and Resolution No. 71/NQ-CP, and it targets Vietnam’s entry into the world’s top 10–20 countries for IPv6 transition [3].

  1. Goals

IPv6 Adoption target by 2030: VNNIC and the Ministry of Science and Technology set an aim that the rate of IPv6 usage in Vietnam will reach 90–100% by 2030, which will place Vietnam among the top 10-20 nations in the world in Internet transition to IPv6 and gradually phase out IPv4 [3].

The IPv6 Only Transition Across the Ecosystem: The IPv6 only program mandates all telecommunications operators, data centers, digital content providers, and government agencies to fully transition to IPv6 only. In parallel, core networks, mobile networks, Wi- Fi, fixed broadband, and government systems will be deployed in a synchronised manner to complete the transition across Vietnam’s Internet ecosystem during 2029–2030 [3].

  1. Deployment Roadmap

Vietnam will transition to IPv6-only in three phases to facilitate a smooth, safe, and scalable migration:

Phase 1 (2026–2027) will involve preparation, technical assessment, pilot deployment, and testing in constrained environments [3].

Phase 2 (2027–2028) will accelerate adoption by major players such as ISPs, data centers, government systems, and digital service providers, with the adoption rate estimated to reach around 80–90% [3].

Phase 3 (2029–2030) will complete the statewide transition, expand IPv6-only deployment across the full ecosystem, and gradually retire IPv4 [3].

Realizing a Managed Transition: IPv6 deployment requires careful planning, multiple migration models, and operational expertise, which supports a staged transition that reduces risks and keeps the migration under control [4].

Shaping a Future-Ready Internet: IPv6 is presented as the only viable long-term option for the expanding Internet, making it a foundation for a more scalable and efficient Internet ecosystem [5].

III. The Role of IPv6 in National Digital Infrastructure

“Strong national strategies, infrastructure investment, and active community engagement” [6] establish the circumstances for long-term digital development, which is why IPv6 serves as a foundational component of Vietnam’s national digital infrastructure, with the country’s robust IPv6 progress being a testament to these efforts. As connectivity demands keep growing, IPv6 is critical for enabling next-generation Internet infrastructure and large-scale digital services, including cloud platforms, data centers, CDN deployment and an IPv6-only future.

1. IPv4 Limitations and the Need for IPv6

Internet Protocol version 4 (IPv4) was deployed since early 1980's. It uses 32-bit addresses that provides a limited number of Internet addresses (232 or about 4.3 billion). As the Internet grows, IPv4 addresses will be exhausted eventually [7].

IPv4 has reached its structural limits, because “the global free pool of available IPv4 addresses has been fully depleted” [7] which creates a huge obstacle for the Internet’s ongoing expansion. The increasing number of connected devices, online services and digital applications, coupled with the paucity of IPv4 addresses, is making it increasingly difficult to serve new customers and build Internet-based businesses in a sustainable manner.

NAT and the End-to-End Model:

This shortage has led many networks to deploy NAT, which fixes short-term address shortages but breaks the fundamental end-to-end communication concept of the Internet and makes the network management more complex [8]. IPv6 is therefore not merely a technical upgrade but a vital basis for regaining direct connectivity, extending address capacity and supporting the long-term evolution of digital infrastructure [9].

2. IPv6 as Digital Infrastructure Foundation

IPv6 as a Core Layer of Digital Infrastructure: IPv6 is a core layer of digital infrastructure with a vast address space of 3.4 × 10^38 addresses, which is enough to accommodate the massive rise of linked devices in IoT, 5G, 6G, cloud systems, and other developing digital applications. Whereas IPv4 was not designed for this scale, IPv6 was built to support the future growth of the Internet at scale, making it a much better fit for long-term digital transformation [10].

Built-in Security and Connectivity: IPv6 also enhances network security with integrated support for IPSec, which promotes data protection and increases users’ trust in digital communication environments. In addition, IPv6 provides direct device-to-device connectivity, reduces translation overhead and latency for real-time and large-scale digital services, and eliminates the need for NAT [11].

Role in Vietnam’s Internet Modernization: For this reason, IPv6 is not a simple replacement for IPv4 but a vital infrastructure technology for supporting the modernization of Vietnam’s Internet ecosystem [3].

IV. Proposed Solutions

To implement the IPv6-only roadmap for 2026-2030, Vietnam needs to concentrate on three practical solutions: phased coordination, infrastructure preparation and human resource development.

1. Phased and Coordinated Transition

Vietnam should continue to implement IPv6-only in distinct steps rather than trying to do it all at once statewide. Phasing it out reduces operational risk, lets technical issues surface early and provides stakeholders plenty of time to change their systems [4]. The shift needs to be synchronised and coordination across government agencies, internet service providers, data centers and content suppliers is necessary. As illustrated in Figure 4, the uptake of IPv6 in Vietnam has increased progressively over time . This justifies the need for a staged and coordinated migration approach.

2. Infrastructure and Service Readiness
Organisations should evaluate network infrastructure, devices, applications and services prior to adoption of IPv6-only [12]. Legacy equipment and incompatible software should be upgraded or replaced gradually so as not to disturb [12]. Core networks, mobile networks, Wi-Fi, broadband systems, cloud platforms and government services are the backbone of the national digital ecosystem and must be prioritised.

3. Human Resources Training and Awareness
This transformation will also require well trained technical workers and more awareness among organisations and users [13]. Training of network administrators, engineers and policy makers in the deployment and troubleshooting of IPv6 is needed [13]. Awareness programmes should also be strengthened to make stakeholders realise the long-term value of IPv6 and to actively support the transition process.

V. Actions for Students and Youth

1. Build IPv6 knowledge
Students and young people should first build a solid understanding of IPv6 concepts, deployment models, and practical troubleshooting skills [14]. This foundation will help them understand why IPv6 is important for Vietnam’s digital infrastructure.

2. Join training activities
They should actively participate in online courses, workshops, and university training programs to strengthen their technical readiness and awareness of Internet infrastructure development. These activities can help turn IPv6 from a theoretical topic into practical knowledge.

3. Spread awareness
Students can also promote IPv6 knowledge among peers through seminars, student clubs, academic discussions, and social media. In this way, they can help spread awareness of the long-term importance of IPv6 in Vietnam’s digital transformation [3][14].

4. Participate in innovation projects
Students can join research projects, labs, Camp, or community initiatives related to networking, IPv6 deployment, Internet governance, and digital transformation [15]. This helps connect classroom learning with real infrastructure needs.

5. Support a digital transformation mindset
Beyond technical learning, students should develop a mindset that values long-term digital infrastructure and national Internet development. This encourages responsible participation in Vietnam’s transition to IPv6 and future technologies [3][14].
