The address layer
for the whole stack.
Prefixx has specialized in IPv4 brokerage since 2018, backed by a team that has worked in the address space since 2007, and it is still the only thing that we do.
One dedicated broker guides your transaction from the first email to the confirmed transfer, and can then help you bring the block live on bare metal. The LOA and the routing paperwork are prepared by our team on your behalf, buyers pay us no fee at all, and secure by escrow.
LACNIC facilitated
Trusted by industry leaders worldwide
Addresses are only half the deal.
Most brokers consider their work finished once the transfer is confirmed. Prefixx shares a holding company with Netrouting, DFDC and LayerSwitch, and because of that the block you buy has a natural home from the day the deal closes. It can be announced from your own ASN on bare metal, while the routing paperwork is taken care of by our team.
From closed deal to announced on bare metal.
Suppose that you buy a block and an ASN through us. You can bring both onto bare metal as BYOIP, and our team takes care of the LOA, the RPKI ROAs and the route objects on your behalf. There is no re-IP project to plan for, and there is no per-IP surcharge attached. Netrouting is our flagship partner on the AS6206 network, and every dedicated service there includes BYOIP and BYOASN as a standard feature.
Every direction on IPv4.
We have deliberately kept our book of listings on the small side, because it allows us to choose what gets listed and on what terms. The consultant who picks up your first call is also the person who sees the deal through to closing.
Buy IPv4
We broker blocks from /24, which is 256 addresses, up to /16, and every block is vetted before it is ever presented to you. As the buyer you pay the block price plus the escrow fee, and nothing more. Our commission comes from the seller, and the due diligence and the registry transfer are handled by our team.
Browse inventory →Sell IPv4
As the seller you pay a commission of between 3 and 8%, depending on the size of the block, and only when the sale actually completes. If there is no sale, there is no fee. We locate the buyer, screen them carefully, and settle the transaction through escrow while the registry paperwork is processed.
Get a valuation →Lease IPv4
Every lease that we write carries a non-revocation guarantee, and RPKI, reassignment and reverse DNS support are included as standard. A fair number of our clients choose to lease first, prove out their use case, and then come back later to buy the space outright.
See lease terms →BYOIP INCLUDED
You can bring space that you already hold onto bare metal or into the cloud. Our team drafts the LOA and arranges the ROA and the route objects on your behalf. It works natively on the Netrouting AS6206 network, and the same space can be announced on AWS, Google Cloud and Azure.
How it works →White-Glove Service
Geo-location corrections, reverse DNS, reputation monitoring, blacklist scanning and abuse handling are all part of the service, and they are included with every lease. Nobody has ever received an extra invoice for any of it.
Our service suite →Inter-RIR Transfers
Moving a block from ARIN to RIPE NCC, for example, brings two registries with two different rulebooks into a single transaction. These transfers tend to run into trouble in predictable places, and after years of handling them we know where those places are.
Transfer options →A broker on your side of the table.
The first RIR free pool ran dry in 2011, and the last one followed in 2020. Everything since then has been a secondary market, with real contracts, real money, and edge cases that catch out the people who have never done this before. Our role is to sit in the middle of the transaction so that they do not catch you.
Multi-regional
Prefixx holds registered broker status with ARIN, RIPE NCC and APNIC, and in the LACNIC region we act as a facilitator rather than as a direct broker. Over the years we have closed work in Europe, the Middle East, Asia-Pacific, Canada and the United States.
No-win-no-fee
If nothing transfers, then nothing is owed, and that is the entire policy. Every cost that you could possibly be charged is put on the table before the work begins, which is the reason that our invoices very rarely lead to discussions.
The middle man
Both sides of the transaction deal with us, rather than with each other. We verify the block, we verify the counterparty, and we keep the funds in escrow until the RIR has confirmed the transfer. Nobody is paid before that point.
Now is the time
There were 4.3 billion IPv4 addresses to begin with, and there will never be any more of them. Prices have trended upward for the better part of a decade. In our experience the people who call us early get considerably better terms than the people who call in a panic.
