Buy IPv4 addresses,
escrow-secured.
Prefixx assists companies with the secure procurement of IPv4 address space. All of the blocks we offer have been vetted in advance, funds are held in escrow until your registry confirms the transfer, and the RIR paperwork is handled for you from start to finish.
A registered broker on every registry that matters.
Prefixx is a registered IP brokerage company with ARIN, APNIC and RIPE NCC, and transfers that involve LACNIC can be facilitated by us as well. Every registry has its own procedures and requirements when it comes to buying IPv4 address space, and over the years our team has become familiar with all of them, including the less obvious parts that tend to slow a transfer down.
The available pool of free IPv4 address space depleted years ago, which means that buying IPv4 addresses today really means buying them on the transfer market. Our team specializes in helping network administrators find the resources they need, when and where they need them, and in securing the process of actually procuring them.
We follow a thorough diligence process that helps us match the right buyers with the right sellers. It is this combination of transparency, research and commitment that has allowed our team to complete many successful transactions across 5 continents.
Of course, buying might not even be the right option for your company. Reach out to our team of IPv4 consultants for a free analysis of your project requirements, read about leasing IPv4 address space instead, or have a look at our lease vs buy comparison first.
Prepared beats surprised.
Compliance with registry regulations is only one of the challenges that comes with procuring IPv4 address space. There is also pre-approval to think about, registry fees, and the special case of legacy space, which follows rules of its own. Over the years we have published guidelines for just about every scenario we have come across, and we walk our clients through each of the steps below.
Requirements
We always start with a free consultation, in which we determine the block size, the region and the budget that you have in mind, and whether buying or leasing is actually the better fit for your situation.
Pre-approval
Where a registry requires it, we will prepare the pre-approval on your behalf. ARIN for example asks for a needs justification, while RIPE and APNIC each have their own membership requirements.
Diligence & escrow
The block is then vetted for reputation, blacklistings and chain of custody, after which the funds are secured in escrow. Nothing moves before that has happened.
Transfer & release
The RIR transfer itself is then executed and confirmed. The escrow is only released to the seller once your registry has confirmed that the block is indeed registered to you.
We'll help you tick the boxes.
Our team assists with every step in purchasing or divesting IPv4 address space. Every block that reaches a buyer has first been passed through Tixx by Prefixx, which is our own quality control checklist covering reputation, routing history and registry standing. If a block does not pass these checks, then it is simply not offered through us, and that is really all there is to it.
White-glove aftercare
It is all in the details. Our team offers geo-location correction, abuse complaint processing, reverse DNS and more, so that your new address space performs the way it should from day one.
Service details →Buying IPv4: common questions
Generally speaking, IPv4 pricing fluctuates based on supply and demand. Factors such as block size, the region (ARIN, RIPE, APNIC, LACNIC) and the reputation of the addresses all play a role, and the market itself moves from month to month. See our pricing and market data page for more detail, or contact Prefixx for a current quote based on your requirements.
Yes, in most cases. The majority of the Regional Internet Registries require some form of pre-approval before an IPv4 transfer can take place. ARIN for example requires a justified need demonstration, while RIPE NCC and APNIC each have their own membership and pre-approval requirements. Prefixx guides you through the entire process, and the filings themselves are prepared by us.
That depends on the registry in question. RIPE transfers can complete in as little as 1 to 2 weeks, while ARIN transfers typically take somewhere between 2 and 6 weeks. The pre-approval and documentation phases will add some additional time on the front end. We keep the paperwork moving, so that the registry review is the only real wait in the whole process.
No. Prefixx does not charge any buyer fees at all. Our service commission is paid by the seller, so as a buyer you are only responsible for the purchase price of the block itself, plus any bank or escrow transaction fees that may apply.
Prefixx facilitates purchases ranging from a single /24, which is 256 addresses, all the way up to /16 blocks and beyond. The minimum transferable block size is set by the registries themselves: both ARIN and RIPE currently allow transfers down to a /24 and no smaller than that.
Funds are deposited into a secure escrow account before any transfer begins, and they are only released to the seller after the RIR has confirmed that the IPv4 block has indeed been transferred to you. This arrangement protects both parties from the beginning of the transaction to the end of it.
Both options have their advantages, of course. Buying gives you permanent ownership of the space, while leasing offers long-term stability with lower upfront costs and a much faster deployment. Compare leasing vs buying to find out which of the two fits your business best.
