Buying IPv4 addresses

Prefixx is a registered IP brokerage company with ARIN, APNIC and RIPE NCC, and also facilitates transfers involving LACNIC. We are familiar with the various RIR procedures and requirements for buying IPv4 address space.

High demand has led to depletion of the available IPv4 address space worldwide. Our team specializes in helping network administrators find resources when and where they need them, and secure the process of procuring them.

Our company follows a thorough diligence process that helps us match buyers with sellers. Transparency, research and commitment have helped our team complete many successful transactions across five continents.

IPv4 Procurement Process

Buying IPv4 address space can get complicated. Compliance with the local Internet registry regulations is only one of the challenges you'll find as you start procuring IPv4. Do you need pre-approval? Are there any registry fees that apply? What about legacy space? These are all common questions that may lead to time consuming issues. Be prepared; Prefixx has published basic guidelines and information about the IPv4 transfer process for the following scenarios:

Frequently Asked Questions

How much does it cost to buy IPv4 addresses?

IPv4 pricing fluctuates based on supply and demand. Factors such as block size, region (ARIN, RIPE, APNIC, LACNIC), and IP reputation all play a role. See our pricing and market data page for more detail, or contact Prefixx for a current quote tailored to your requirements.

Do I need pre-approval before buying IPv4?

Yes. Most Regional Internet Registries require pre-approval before an IPv4 transfer can take place. ARIN requires a justified need demonstration, while RIPE NCC and APNIC have their own membership and pre-approval requirements. Prefixx will guide you through the entire process.

How long does it take to buy IPv4 addresses?

The timeline varies by registry. RIPE transfers can complete in as little as 1-2 weeks, while ARIN transfers typically take 2-6 weeks. The pre-approval and documentation phases add additional time. Prefixx works to streamline every step of the process.

Are there any buyer fees with Prefixx?

No. Prefixx does not charge buyer fees. Our service commission is paid by the seller. As a buyer, you are only responsible for the block purchase price and any bank or escrow transaction fees.

What sizes of IPv4 blocks can I buy?

Prefixx facilitates purchases ranging from a single /24 (256 addresses) to large /16 blocks and beyond. The minimum transferable block size varies by registry: ARIN allows /24 transfers, while RIPE requires a minimum of /24 as well.

How does the escrow payment process work?

Funds are deposited into a secure escrow account before any transfer begins. The funds are only released to the seller after the RIR has confirmed the successful transfer of the IPv4 block to the buyer. This protects both parties throughout the transaction.

Not sure whether to lease or buy?

Both options have their advantages. Buying gives you permanent ownership, while leasing provides long-term stability with lower upfront costs and faster deployment. Compare leasing vs buying to find the right fit for your business.
