About Prefixx

A boutique IPv4 brokerage built on transparency, expertise, and long-term relationships.

Our Story

Prefixx was founded in 2018 by a team that has been working in the data center and networking industry since 2007. Headquartered in Miami, Florida at 1200 Brickell Avenue, we serve clients across five continents — from emerging startups to publicly traded enterprises.

We are not a marketplace. Prefixx takes a boutique approach to every engagement: each client works directly with a senior consultant who understands the technical, legal, and financial complexities of IPv4 transactions. No ticket queues, no junior handoffs — just experienced professionals who guide you from first conversation to completed transfer.

Our team has successfully completed hundreds of IPv4 transactions across all major Regional Internet Registries, handling everything from straightforward /24 purchases to complex multi-million-dollar portfolio divestitures and cross-region inter-RIR transfers.

Prefixx mission — working together with transparency and integrity

Our Mission

We exist to help companies navigate the IPv4 market with confidence. As available address space becomes scarcer and more valuable, organizations need a trusted partner who can provide honest market guidance, thorough due diligence, and a transparent transaction process.

Every engagement at Prefixx starts with a conversation — not a sales pitch. We listen to your requirements, assess your options, and recommend the approach that best fits your budget, timeline, and long-term strategy. Whether that means buying, selling, leasing, or a combination of all three, our goal is to deliver outcomes — not just transactions.

How We Work

No-win, no-fee. If we don't close the deal, you don't pay. Our commission (3 – 8%, depending on block size) is charged to the seller only. Buyers pay zero broker fees — just the block purchase price and any escrow or bank transaction fees.

Escrow-protected. All purchase transactions are handled through independent escrow, ensuring funds are only released when the IPv4 transfer is officially confirmed by the relevant RIR. No risk to either party.

Full-service. We manage every detail — from sourcing and due diligence to legal documentation, RIR coordination, and post-transfer support. Our White-Glove service includes blacklist scanning, geolocation correction, RPKI setup, and reverse DNS management at no additional cost.
