Vietnam IPv4 Shortage: Buying Strategies for Foreign Firms

You finally got approval to launch in Vietnam, and the first technical question hits you: where do you get a Vietnam IPv4 address for your servers, VPN, or email infrastructure? The Asia-Pacific region ran out of IPv4 space years ago, and Vietnam's local registry has been operating on its final /8 block since 2015. The pool is down to a fraction of what it was. For a foreign company without a local entity, buying a Vietnam IPv4 outright is harder than it looks. This guide covers the buying strategies that actually work in 2026 and the practical alternatives that most foreign businesses end up choosing instead.

Key takeaways

• Vietnam's IPv4 pool is nearly exhausted; the local registry is down to a small fraction of its original /8 block, so new allocations to foreign companies are rare.
• Buying IPv4 outright in Vietnam requires a local entity or a long-standing relationship with a local provider, and prices have climbed to $40-$60 per IP on the open market.
• Leasing IPv4 from a local provider or renting a Linux VPS with a dedicated Vietnam IPv4 is faster, cheaper, and legally simpler for most foreign businesses.
• IPv6 is technically available but adoption in Vietnam is still low, so it cannot replace IPv4 for reaching local users and partners today.

Why is Vietnam IPv4 address scarcity so severe in 2026?

Vietnam's internet grew faster than anyone predicted. The country went from a few million users in the early 2000s to over 78 million internet users by 2025, and every smartphone, bank server, and IoT device needs an address. The Asia-Pacific Network Information Centre (APNIC) exhausted its IPv4 pool in 2019, and Vietnam's national registry, VNNIC, received its last allocation years before that. What remains is a shrinking pool of addresses held by ISPs, datacenters, and enterprises that have no incentive to give them up.

For a foreign company, the scarcity is amplified twice. First, the global IPv4 market now trades addresses at $40-$60 each, and that price has been climbing steadily since 2020. Second, Vietnam's regulations on IP address management require a local entity or a cooperative local partner for most direct allocations. You cannot simply fly in, register a company, and request a /24 block the way you could a decade ago.

The result is a two-tier market. Large local ISPs and datacenters hold the bulk of remaining addresses and lease them as part of hosting services. The open market for buying addresses outright is thin, slow, and filled with compliance checks. Understanding this split is the key to choosing a strategy that works for your timeline and budget.

Can a foreign company buy a Vietnam IPv4 address directly?

The short answer is: usually no, not without help. VNNIC allocates IPv4 addresses to licensed ISPs and datacenter operators in Vietnam, not to end customers. A foreign company without a Vietnamese entity cannot apply for a direct allocation. Even with a local entity, VNNIC requires justification, a demonstrated need, and a track record of using the addresses within the country.

What foreign companies actually do falls into three buckets:

1. Buy from a broker or transfer market: APNIC allows IPv4 transfers, but the buyer must be a member of APNIC, which requires a presence in the region and membership fees. This route works but takes months and carries legal overhead.
2. Lease from a local provider: Many Vietnamese ISPs and Linux VPS providers offer a dedicated IPv4 as part of a hosting plan. You do not own the address, but you get exclusive use of it, which is what matters for most workloads.
3. Use a local partner or subsidiary: If you have a Vietnamese entity, that entity can apply for addresses or work with a local ISP on your behalf. This is the route for companies that need large blocks for infrastructure.

The table below summarizes the practical options.

Strategy 1: renting a VPS with a dedicated Vietnam IPv4

For 9 out of 10 foreign businesses, the smartest move is not to buy an IPv4 address at all. It is to rent a VPS that includes a dedicated IPv4 in the Vietnam range. You get a real, routable address from Vietnam's address space, and it is yours exclusively for as long as you rent the server. When you are done, you stop paying and the address goes back to the pool. No transfer paperwork, no APNIC membership, no months of waiting.

This works for almost every use case: running a website for local users, setting up an email server, testing a VPN, or hosting an API that needs a Vietnamese IP for latency reasons. Rent a Linux VPS with this model and you can be running within an hour of signing up. Full root access means you control the network stack, the firewall, and everything else, exactly as if you owned the address.

What you give up is the permanence of ownership. If your strategy depends on owning the address as an asset, this will not satisfy that requirement. But for operational needs, a leased address on a VPS behaves identically to a bought one. The IP is static, it is dedicated to your account, and it resolves correctly in rDNS and DNS records.

Before you commit, verify the specific address range works for your use case. Run a reverse DNS check, test whether the IP is on any blacklists, and confirm the provider documents the IP as Vietnamese. A blacklisted IP check is a five-minute task that saves you weeks of email deliverability pain later; read our guide on Vietnam VPS vs offshore VPS for local traffic to see why location matters for latency.

Strategy 2: leasing IPv4 blocks from local providers

If you need more than one or two addresses, say a /29 (8 addresses) or a /28 (16 addresses), direct leasing from a Vietnamese ISP or datacenter becomes more cost-effective than stacking VPS plans. Many providers in Tier 3 datacenters like Viettel IDC and VNPT IDC offer IP leasing to companies that also host their servers locally, and some offer it as a standalone service.

The leasing model works like this: the provider owns the address block, you get exclusive use of a defined subset, and you pay a monthly or annual fee. The provider handles the routing and the registry paperwork. Your responsibility starts at the network interface. This is the standard model for email servers, game servers, and any workload that needs multiple clean IPs. For bulk email sending, a clean SMTP VPS with several dedicated IPs is the difference between inbox and spam folder; see why a clean dedicated IP SMTP VPS matters for deliverability.

Practical tips for leasing:

• Ask for the address block's history. A block that was used for spam will hurt you no matter how good your setup is.
• Confirm the provider can set rDNS (PTR records) for the IPs you lease. Email and many network services fail without it.
• Get the terms in writing, especially what happens to the IPs if you cancel and want to migrate.
• Test latency from your target region before signing a longer contract.

Strategy 3: buying IPv4 via APNIC transfer market

For companies that genuinely need to own addresses, the APNIC transfer market is the only legitimate route. The process involves becoming an APNIC member, finding a seller with a Vietnam-registered address block, and completing a due diligence process that can take weeks. The cost is the market price per address, which in early 2026 sits around $40-$60 per IP, plus APNIC membership fees and legal costs.

The catch is that Vietnam-registered blocks rarely come up for sale. Most were allocated to ISPs that use them for hosting and infrastructure. When blocks do appear, they are often at a premium. The alternative is buying a block from another APNIC economy and attempting to transfer it to Vietnam, but VNNIC's policies on incoming transfers are restrictive, so this is not a reliable path.

You also need to think about why you want to own the address. If the goal is control, a lease gives you that control for operational purposes. If the goal is asset appreciation, IPv4 prices have risen for years, but a Vietnam-specific block carries regulatory risk that global blocks do not. The transfer market is a serious commitment, and most foreign businesses find the operational equivalent through leasing or VPS hosting.

What about IPv6 as an alternative?

IPv6 is the long-term answer to address exhaustion, and Vietnam has made progress. The country's IPv6 adoption rate climbed above 60% during 2024-2025, driven by government mandates and mobile network upgrades. But that progress is uneven. Many local services, older servers, and enterprise networks still run IPv4-only, and foreign companies building services for Vietnamese users cannot assume IPv6 reachability.

For new infrastructure, running dual-stack is the professional approach. You keep a dedicated IPv4 for compatibility and add IPv6 for growth. Most modern VPS providers in Vietnam support dual-stack, and tools like Nginx and Docker handle both protocols natively. My practical advice: do not design anything that depends only on IPv6. Treat it as a bonus, not a replacement.

Practical checklist for foreign businesses getting a Vietnam IPv4

Whatever route you choose, work through this checklist before committing:

1. Define how many IPs you need and for what workload (web, email, VPN, game server).
2. Check the target IP's blacklist status and history before paying.
3. Verify the provider configures rDNS for the address.
4. Confirm the IP is genuinely in the Vietnam range, not a foreign address routed through Vietnam.
5. Test latency and throughput from your users' actual location, not your own.
6. Read the provider's terms on IP portability and cancellation.

Which strategy should you pick?

Most foreign businesses should start with strategy 1: rent a VPS with a dedicated Vietnam IPv4. It is fast, cheap, and reversible. The address behaves like a permanent allocation for operational purposes, and the monthly cost is trivial compared to the effort of buying. If you scale and need multiple addresses, move to strategy 2 and lease a small block. Reserve strategy 3 for the rare case where you have a local entity, a long-term infrastructure plan, and a budget for legal and APNIC fees.

One note on cost: providers vary widely in how they price IP allocation. A plan that looks cheap may hide setup fees or require annual prepayment. Always read the terms. For a quick start, look at a Windows VPS or Linux option with a documented Vietnam IPv4 and monthly billing, so you are not locked in while you evaluate the market. The address scarcity is real, but the workarounds are proven and mature.
