Buy IP Address USA: The Complete Guide for Businesses in America

Buy an IP Address USA: The Complete Guide for Businesses in America

As digital businesses grow and global platforms need stable, compliant, and reputation-safe IP ranges, the need for IPv4 address space in the United States keeps going up. If you run a data center, a hosting company, a SaaS platform, a VPN service, or a business network that is growing, you need your own dedicated IPv4 addresses to keep things running smoothly, protect your data, and manage your resources. This guide tells U.S. businesses everything they need to know about buying IPv4 address ranges, such as how to follow ARIN rules, what to expect in terms of prices, and the best way to protect clean American IP space.

Why U.S. businesses still need IPv4 in 2025

Even though IPv6 is slowly being adopted, American businesses still rely on IPv4 a lot because:

1. IPv4 is still used by old systems.
   Many business systems, like CRM tools and enterprise firewalls, only work with IPv4.
2. The U.S. still hasn’t fully adopted IPv6.
   Comcast and Verizon, two big companies, have made it easier to roll out IPv6, but many corporate and SaaS networks still rely on IPv4 or are dual-stack.
3. People all over the world trust U.S. IPv4 addresses a lot.
   Compared to some international networks, American IPv4 ranges often have better email delivery, cleaner geolocation trust, and a better reputation.
4. The lack of IPv4 drives long-term value.
   ARIN ran out of IPv4 years ago, so U.S. IPv4 has become a digital asset with steady demand and a rising market value.

This makes it a smart and long-term investment to buy IP address blocks in the US.

Where U.S. IPv4 Addresses Come From

In the United States, IPv4 space is governed by ARIN (American Registry for Internet Numbers). Since ARIN’s pool is fully depleted, the only way businesses can acquire IPv4 is through:

• Transfers between organizations
• IPv4 brokers
• Leasing services
• Secondary market purchases

Because the U.S. IPv4 market is regulated, buyers must follow ARIN policy even when purchasing from a private seller or broker. Unlike many international markets where blocks might be listed by sellers in countries like the Netherlands, Sweden, or Germany and transferred across RIPE, APNIC, or LACNIC regions, U.S. buyers are subject to ARIN’s transfer rules, documentation requirements, and due diligence processes. This means that whether you’re acquiring a /24 (256 IPs) or a much larger /16 (65,536 IPs) block, your transaction must meet ARIN’s strict standards for justification, transfer approval, and clean title.

What to Expect When Buying U.S. IPv4 Blocks

• Size and Price Transparency: IPv4 blocks come in various sizes /24, /23, /22, /21, and up, each representing a different number of IP addresses. U.S. market prices, while variable, are generally quoted per IP and depend on block size, reputation, and recent sales. As of 2024, prices typically range from $30 to $60 per IP, with larger blocks often commanding a lower per-IP rate.
• Transferability: U.S. IPv4 blocks are transferable within ARIN and, in some cases, can be transferred to or from other regions (RIPE, APNIC, LACNIC), provided both registries’ policies are followed. However, ARIN’s standards tend to be among the strictest, emphasizing clean history and compliance.
• Seller Location and Compliance: While global sellers may offer blocks that are “transferable to ARIN,” only addresses properly registered and cleared through ARIN will be recognized for U.S.-based use. This adds a layer of security but also means extra paperwork compared to some international deals.
• Due Diligence: U.S. buyers should always verify the origin, allocation status (legacy, allocated, assigned), and reputation of a block before purchase. Cleanliness, meaning the block isn’t blacklisted or carrying a spam reputation, is crucial for long-term value.

By understanding these nuances and ARIN’s compliance requirements, U.S. businesses can avoid pitfalls and ensure they’re investing in IPv4 space that is both reputable and future-proof.

What Makes This IPv4 Marketplace Different from Traditional Auctions?

Most buyers are used to the old-school auction process, lengthy bids, last-minute sniping, paperwork marathons, and a whole lot of waiting for the right block to come along. This marketplace flips that script. Here, you’ll find a straightforward “Buy Now” option: no drawn-out bidding wars or second-guessing if your offer will win.

You simply create an account, pick the IPv4 blocks that fit your needs, and purchase them immediately, just like shopping on Amazon, but for IP addresses. Everything’s built for speed and predictability, so you get the blocks you want, right when you need them, minus the usual uncertainty.

Country of Seller for Each IPv4 Block Offer

When searching for IPv4 blocks in today’s market, you’ll notice they often come from different corners of Europe and beyond. Here’s a quick snapshot of countries currently selling IPv4 blocks, based on recent offers available on the secondary market:

• The Netherlands: Frequently appears as a seller of /19, /18, /17, /23, and /24 blocks (both legacy and allocated), making it one of the most active sources.
• Sweden: Offers several/21 and /22 blocks, primarily PA-allocated ranges.
• Italy: Occasionally listed as a seller, particularly for smaller /22 blocks.
• United Kingdom: Tends to list legacy blocks in various sizes, such as /21, /19, and /20, as well as some allocated /21 ranges.
• Australia: Sells /23 blocks, typically under the APNIC registry.
• Germany: Known for higher-priced, PA-allocated blocks including /20, /22, /23, and /24.
• Romania: Occasionally offers /24 PI-assigned blocks.

Countries like these are common sources for IPv4 space on the open market, but if your goal is ARIN-region or U.S.-specific space, make sure you double-check the region of allocation and transferability policy before moving ahead. Blocks can often be transferred between RIRs, but the originating country is important if you have geolocation or compliance needs. Boxed in by ARIN’s rules? You’re not alone; many global networks are facing the same bottleneck.

Now, let’s look at why buying American IPv4 address blocks is uniquely valuable compared to options from these international sellers.

Understanding U.S. IPv4 Address Statuses

When exploring the U.S. IPv4 market, you’ll encounter a few common status types attached to address blocks. These designations are important, as they can determine how easily you can transfer, use, or manage your IPs:

• Allocated: These address blocks are currently assigned by ARIN to organizations for network use. They’re actively managed under standard policy and typically have clear transfer histories.
• Legacy: These IP ranges were assigned before ARIN’s establishment in 1997. While still routable, legacy space may involve different policy considerations and sometimes lacks up-to-date documentation or contact info.
• Assigned PI (Provider-Independent): These are blocks given directly to end-users rather than ISPs. They offer more autonomy, allowing you to move the address space between providers as needed.
• Allocated PA (Provider-Aggregatable): These ranges are assigned to ISPs, who in turn allocate them to their own customers. They’re generally portable only within a provider’s network, making their transfer process a bit more limited.

Understanding each status can help you choose the right type of IPv4 space for your business’s needs and growth plans.

Key Benefits of Buying U.S. IPv4 Address Blocks

Purchasing American IP ranges offers several unique advantages:

1. Better geolocation trust

Search engines, ad platforms, and cloud services recognize U.S. IPv4 blocks as reliable, reducing the risk of misrouting or misclassification.

2. Improved email deliverability

U.S. IPs often have a cleaner reputation, which helps marketing, CRM, and transactional email systems.

3. Ideal for U.S.-based hosting and SaaS platforms

If your customers are in America, U.S. IPv4 ensures faster routing and compliance alignment.

4. Strong market stability

American IPv4 pricing is more stable compared to some international regions.

5. ARIN-verified ownership

After transfer, your organization becomes the official holder of the IPv4 block in ARIN’s registry.

Long-Term Support and Scalability for U.S. IPv4 Buyers

When you purchase U.S. IPv4 address blocks, you’re not just making a one-time investment; you’re building the foundation for ongoing growth and future-proofing your business networks.

Here’s how credible brokers and partners help make that a reality:

• Scalable Solutions: Top-tier brokers and ARIN-registered consultants help you right-size your IP purchase, scaling up as your data center, SaaS platform, or cloud service expands. You don’t have to “buy big” all at once. Trusted advisors guide you in acquiring additional IP blocks over time, whether you’re adding another rack in Ashburn or spinning up new locations in Dallas or Phoenix.
• Expert Guidance: From handling initial ARIN paperwork to long-term planning, knowledgeable partners (including those certified by ARIN and members of organizations like NANOG and RIPE NCC) keep you informed about regulatory shifts, IPv6 transition paths, and market price trends. This advice is especially helpful when your tech roadmap changes or compliance needs arise.
• Ongoing Reputation Monitoring: Maintaining a clean reputation is crucial for everything from email deliverability (think Mailgun or Sendgrid integrations) to digital advertising success. Some brokers and IP management firms offer reputation audits and blacklist monitoring so you don’t inherit legacy problems and can keep your IP space “clean” as your business grows.
• Support for Transfers and Upgrades: If you outgrow your initial allocation or need to lease, transfer, or subdivide your IP block, ARIN-verified brokers can manage the administrative heavy lifting. This future flexibility means your IP investment adapts as your network strategy evolves.

In short, buying U.S. IPv4 addresses comes with the backing of a mature support ecosystem, making it possible to scale and protect your investment both today and as your business needs change.

How AWS’s New IPv4 Charges Impact Buyers and Why BYOIP Might Save You Money

If your business relies on platforms like AWS, it’s important to know that Amazon recently started charging for public IPv4 addresses. This move was a direct response to the global IPv4 shortage and the rising costs to maintain these resources.

What does this mean for you?

• Higher operational costs:
  AWS now applies a monthly fee for every public IPv4 address you use. For companies managing dozens, hundreds, or even thousands of cloud-based resources, these recurring costs add up fast.
• Motivation to control your own IP space:
  If you bring your own IP (BYOIP) blocks to AWS, you might be able to sidestep some of these new charges. AWS allows customers to use privately owned IPs within their cloud infrastructure, potentially eliminating or reducing fees for rented AWS-managed address space.

The bottom line

If you purchase a U.S. IPv4 block and use it with cloud providers like AWS, Google Cloud, or Microsoft Azure, you gain greater control and may enjoy significant cost reductions over time.

• Cost savings:
  For most growing businesses, especially those with stable or expanding operations in the U.S., bringing your own IP space can quickly offset the initial purchase price due to lower monthly hosting charges.
• Strategic value:
  Owning your address block means you’re not at the whim of third-party price hikes and can move workloads more freely among cloud providers.

In short, as large cloud players like AWS begin to charge for every IPv4 address, owning your own block becomes not just a technical advantage, but a financial strategy for future-proofing your infrastructure.

How the “Buy Now” Option Simplifies IPv4 Acquisition

For businesses that want to avoid lengthy back-and-forth negotiations or auction drama, many U.S. IPv4 marketplaces now offer a straightforward “Buy Now” feature. Here’s how it typically works:

• Browse Available Blocks: You log in, browse the ranges that are immediately available, often pre-cleared for quick transfer, and see fixed pricing up front. No guessing, haggling, or waiting for an auction to end.
• Purchase in Minutes: Simply choose your IPv4 block, hit “Buy Now,” and complete your payment securely, just like you would on Amazon or GoDaddy.
• Immediate Reservation: The IP block is reserved for you as soon as the transaction goes through, taking the uncertainty out of the process.
• Fast, Verified Transfers: The marketplace (or broker) handles all necessary ARIN transfer paperwork, and compliance thinks of it as the fast lane for acquiring legitimate, clean IP space.

This approach works especially well if you need to scale up quickly, replace blacklisted space, or lock in pricing during a volatile market. It dramatically reduces wait times and offers peace of mind, making the process accessible even for IT teams without deep experience in IP trading.

Steps to Buy IPv4 Addresses Safely in the USA

Because U.S. IPv4 addresses are scarce and valuable, the buying process requires careful steps.

1. Work with a Trusted IPv4 Broker

The safest option is to use a verified broker who specializes in ARIN transfers. A broker:

• Verifies seller ownership
• Confirms reputation and blacklist history
• Handles escrow and secure payments
• Manages ARIN documentation
• Assists with technical and administrative steps

This removes the risk of fraud, contaminated IP blocks, or transfer delays.

2. Inspect the IP Range for Clean Reputation

Before buying, ensure the block is:

• Not listed on spam blacklists
• Not associated with malware or abuse
• Not previously hijacked or misrouted
• Free of geolocation conflicts

Tools like IPv4 Hub’s blacklist checker let U.S. buyers validate ranges instantly.

3. Prepare ARIN Justification (If Required)

Depending on block size, ARIN may require justification for additional IPv4 usage. A broker helps prepare:

• Usage documentation
• Network growth plans
• Technical need statements

This ensures ARIN approval without delays.

4. Complete a Verified ARIN Transfer

Once everything is approved, the transfer moves into the compliance phase:

• Contract and escrow
• ARIN transfer request
• Seller and buyer verification
• Registry records updated
• Buyer receives full ownership

After completion, the buyer can announce and use the range immediately.

To streamline these final steps, reputable brokers provide detailed guidance and all necessary documentation to ensure your new IPv4 addresses are operational and in full compliance, often within 24 hours of payment. This optimized process is designed for efficiency and minimizes downtime, so you can integrate your new IP block into your network environment quickly and with confidence. Every phase, from final paperwork to technical integration, is handled with care to ensure a smooth transition and operational excellence.

5. Validate the Block Post-Transfer

After ARIN updates your organization as the new holder, finalize:

• Routing configuration
• New WHOIS and geolocation updates
• Cleanliness re-check
• Internal documentation
• Network monitoring setup

This ensures your new U.S. IPv4 block is functional and reputation-safe.

How Much Do IPv4 Addresses Cost in the USA?

Pricing varies depending on:

• Block size (/24, /23, /22, etc.)
• Clean reputation
• Current market supply
• RIR region (U.S. IPv4 often carries premium value)

Typical U.S. pricing in 2025 ranges between $40–$60 per IP, with discounts for larger blocks. Clean, ARIN-verified space is always priced higher due to trust and compliance guarantees.

Common Block Sizes Available

When buying IPv4 addresses in the U.S., you’ll find a variety of block sizes to match your needs. Here’s a quick rundown of typical options:

• /24 — 256 IPs (most common entry-level block)
• /23 — 512 IPs
• /22 — 1,024 IPs
• /21 — 2,048 IPs
• /20 — 4,096 IPs
• /19 — 8,192 IPs
• /18 — 16,384 IPs
• /17 — 32,768 IPs

Larger blocks are available but increasingly rare, and they typically command a higher price per IP due to scarcity and operational convenience.

What to Expect When Browsing Offers

• Large inventories are available, but premium U.S. blocks move quickly due to high demand.
• Most transactions are streamlined and secure, with professional guidance throughout.
• Buyers can expect access to clean, reputation-safe ranges, especially when working with reputable brokers.
• Pricing and availability may fluctuate, so acting promptly is recommended when suitable space becomes available.

Ensuring Pricing Transparency for U.S. IPv4 Address Purchases

Transparent, upfront pricing is essential when budgeting for IPv4 acquisitions. In the U.S. market, reputable brokers and marketplaces make it easy for buyers to see exactly what they’re paying for by:

• Displaying clear per-IP and per-block rates, often in USD, with no mystery fees lurking in the fine print
• Detailing which costs are included (such as broker fees or standard documentation) and which are not (like ARIN transfer fees or any applicable sales tax)
• Providing itemized quotes and contracts that separate each component of the purchase, ensuring there are no hidden surprises

This clarity is modeled after established platforms like IPv4.Global or Hilco Streambank allows buyers to make smart, confident decisions. With pricing fully disclosed before any agreements are signed, U.S. organizations can accurately forecast their investment and avoid budgetary pitfalls.

Additional Fees and Taxes to Consider

When budgeting for your U.S. IPv4 purchase, remember that advertised prices typically do not include additional regulatory and tax-related costs. Be prepared for the following:

• Regional Internet Registry (RIR) transfer fees: Organizations like ARIN, APNIC, or LACNIC may charge a transfer fee depending on where the block is registered and who manages the transfer. This fee varies by registry and is paid in addition to the purchase price.
• Value Added Tax (VAT): If your organization is located in a VAT-applicable region, the transaction may be subject to VAT, which is charged separately.
• Currency differences: While U.S. pricing per IP is often shown for clarity, payments are typically finalized in EUR or the applicable local currency. Always confirm the exact currency and conversion rate involved.

Factoring these items into your planning ensures you avoid surprises and can confidently complete your IPv4 acquisition.
