Buy Vietnam IPv4 Address for Foreign Companies in 2026

Your users are in Vietnam, your business is registered in Singapore, and your application needs a local IPv4 to serve them properly. You cannot just buy a Vietnam IPv4 address off the shelf. IP space is allocated by APNIC, and the rules for foreign companies are stricter than most people expect. This guide walks through the realistic paths to acquire a Vietnam IPv4 address for your foreign company, what each option costs, and how to manage the address once you have it.

Key takeaways

• APNIC IPv4 allocations require a legal entity in the APNIC region plus membership fees and annual fees. For most foreign companies, renting a Linux VPS with a dedicated IPv4 is faster and cheaper.
• A VPS with a dedicated IPv4 gives you a Vietnam IP immediately, with full root access and the ability to set rDNS, which is often all a business actually needs.
• IP reputation is shared. What you do with the address affects deliverability and access to services like Google and Facebook.
• Monthly billing VPS plans let you test a Vietnam IPv4 for a local project without a long-term commitment.

Why a Vietnam IPv4 address matters for your business

Latency is not the only reason to get a Vietnam IPv4. Many services geo-target by IP. A user in Hanoi visiting a site that resolves to a Singapore IP sees Vietnamese content at best, or gets blocked at worst. Payment gateways, banking APIs, and government portals in Vietnam routinely check the source IP. If your integration talks to a Vietnamese bank, a local IP is often a hard requirement.

There is also the reputation angle. Vietnamese ISPs and email providers treat foreign IPs with suspicion. A Vietnam IPv4 that has been used responsibly has a clean history. A foreign IP that was previously used for spam carries baggage you cannot easily remove. When you buy VPS Vietnam with a dedicated IPv4, you get an address from the local range, and you control its reputation from day one.

Can a foreign company buy a Vietnam IPv4 address directly?

Technically, yes. Practically, it is rarely the right move. IPv4 addresses in the APNIC region are allocated to members, and APNIC membership requires a legal entity registered in the region. A Singapore or US company can incorporate a subsidiary in Vietnam, register with APNIC, pay the membership fee, and request an allocation. The process takes months and costs thousands of dollars before you receive a single IP.

The alternative is to buy address space on the transfer market. APNIC allows 8.3 transfers, where a company can purchase IPv4 blocks from existing holders. The catch is that both parties must be APNIC members, and the receiving side must justify the need. Prices on the transfer market have been volatile, but they consistently sit well above what a small business wants to pay for one IP.

For the vast majority of foreign businesses, renting a Vietnam VPS with a dedicated IPv4 is the only sensible path. You get a local IP, you pay monthly, and you can walk away when the project ends.

Renting a Vietnam VPS with a dedicated IPv4

This is the fastest way to get a Vietnam IPv4 address for a foreign company. A VPS provider in Vietnam assigns you a dedicated IPv4 from the local range as part of the service. You get full root access, you can install whatever you need, and you control the reverse DNS record for the address.

When you rent a VPS in Vietnam, check that the IPv4 is actually dedicated rather than shared. Some budget providers use NAT and give you a private IP with port forwarding. That does not give you a real Vietnam IPv4. You want a provider that assigns a public IP directly to your virtual machine, with no address translation in between.

Here is what to check before you rent:

• Dedicated IPv4 on the public interface, not NAT behind a shared address.
• rDNS control so you can set a reverse DNS record that matches your domain.
• Monthly billing VPS so you are not locked into an annual contract for a test project.
• Snapshots and backups so you can roll back if a configuration change breaks something.

thueVPS offers Linux and Windows VPS plans with a dedicated IPv4 from the Vietnam range, NVMe storage, and full root access. A cheap VPS Vietnam plan starting around 189,000 VND per month gives you a local IP for less than the cost of a domain.

Which OS to run on your Vietnam IP

Once you have the IP, the operating system matters less than the workload. For a simple reverse proxy or a small application, Ubuntu 24.04 or Debian 12 is the default choice. For .NET workloads, Windows Server is the pragmatic option. For automation workflows, you might want n8n preinstalled to avoid the setup time.

The OS does not change the IP address or its geolocation. The IP belongs to the hosting provider's range regardless of what runs on top. What changes is how you manage the server and how much memory it consumes. A SaaS tool running behind Nginx on a 2GB RAM VPS is a different beast from a Windows Server with a GUI eating 2GB before you log in.

Pick the OS that matches your team's skills. If your team knows Linux, stay on Linux. If your application is built on .NET, rent Windows VPS and skip the compatibility layer. Do not choose an OS because of the IP. The IP is the same either way.

Setting up reverse DNS and keeping the IP clean

Reverse DNS is the first thing to configure after you get your Vietnam IPv4. An IP without a PTR record is treated as suspicious by many mail servers and monitoring services. Set the rDNS to a hostname that matches your domain, like mail.yourcompany.com if you send email or yourcompany.com for a web server.

To check what the current rDNS is for your IP:

dig -x 203.113.xxx.xxx +short
host 203.113.xxx.xxx

The output should show the hostname you configured. If it shows a generic provider hostname, contact support and ask for a change. Most providers, including thueVPS, offer free rDNS setup on request.

Keep the IP clean by following basic hygiene:

• Do not send marketing email from an IP that was never warmed up.
• Set SPF, DKIM, and DMARC records before sending any mail.
• Monitor the IP against public blacklists periodically.
• Respond to abuse reports promptly, even if the complaint is not yours.

An IP with a poor reputation is hard to fix. An IP that is new and clean is easy to keep that way if you are careful from the start.

Legal and compliance notes for foreign companies

Vietnam has data localization rules that affect where personal data of Vietnamese users can be stored. Decree 53, which took effect in 2025, requires foreign companies providing services in Vietnam to store certain data within the country. A Vietnam IPv4 is not a substitute for compliant infrastructure. You still need to understand which data must stay local and which can cross borders.

Operating a server on a Vietnam IP does not require a local business license for most use cases. Hosting your own application is different from providing telecommunications services, which do require licensing. If you are running a website or an API for your own business, renting a VPS in Vietnam is a normal commercial transaction, not a regulated activity.

That said, if you plan to offer services to the Vietnamese public at scale, consult a local lawyer. The regulatory landscape is shifting, and what is acceptable today might require a license tomorrow. The IP address itself is neutral. It is the service that attracts scrutiny.

When renting beats buying an IP block

If you need one IP or even ten, renting is the answer. The APNIC route costs thousands of dollars in membership and fees, and the transfer market prices IPs at a premium. A VPS with a dedicated IPv4 costs a few dollars a month and gives you everything a single IP user needs.

Renting also gives you flexibility. You can scale from a 2GB RAM VPS to a 8GB RAM VPS without changing your IP. You can reinstall the OS, create snapshots, and move workloads between servers. If the project ends, you stop paying and release the address back to the pool. That flexibility is worth more than owning an address that you cannot easily sell.

Ownership makes sense only when you need a large block, or when you want to control the IP independently of any hosting provider. For a foreign company serving Vietnamese users, that day rarely comes.
