We help organizations identify, regularize and transfer legacy IPv4 resources — through direct acquisition or structured intermediary processes aligned with RIPE policies.
Prefixium operates at the intersection of technical stewardship and transaction execution. We begin with registry accuracy and policy compliance, then enable acquisition or divestment when appropriate. Our approach reduces governance friction without creating commercial pressure.
Prefixium is an independent technical organization dedicated to the stewardship and regularization of legacy IPv4 address space. We operate with strict neutrality and in full alignment with Regional Internet Registry (RIR) community policies and procedures.
Our mission is to uphold IP address registration integrity and promote responsible governance of Internet number resources. We combine technical expertise with transaction capability to provide end-to-end support for legacy IPv4 management — from assessment to execution.
In-depth technical analysis of historical address records, usage patterns, and registry compliance to establish legitimate holdership and identify irregularities.
We act as direct counterparty for organizations holding unused legacy IPv4 blocks, handling the complete technical, administrative, and registry process.
Neutral intermediary support for corporate holders with fragmented legacy resources, structuring execution paths for consolidation, transfer, or divestment.
Complete management of RIPE NCC, ARIN, and other RIR processes, policy compliance, data validation, and risk mitigation for legacy allocations.
Prefixium operates at the intersection of Internet governance and transaction execution. We are not a generic broker. Our work begins with technical clarity and registry alignment, ensuring responsible, compliant outcomes.
Our role is to reduce friction, not create pressure. We evaluate each situation independently and structure solutions appropriate to the context — whether that means direct acquisition, intermediary support, or advisory-only engagement.
No. We provide both advisory and execution services, including direct acquisition and intermediary-led transactions, depending on the context and requirements of each situation.
Yes. All our operations are aligned with RIPE NCC, ARIN, and other Regional Internet Registry requirements. Policy compliance and registry accuracy are foundational to our approach.
Both. We prioritize technical accuracy first, ensuring registry compliance and risk mitigation. Transactions are enabled only when appropriate and always structured to meet policy requirements and governance standards.
Our governance model is built on transparency, community oversight, and full policy compliance.
Prefixium adheres to principles established by the global RIR communities, ensuring that our activities always reflect the broader interest of Internet stability. Our core principles include:
Neutrality and independence — We remain impartial and free from conflicting interests, focusing solely on stewardship objectives and policy-aligned outcomes.
Policy compliance — All actions strictly follow the policies and procedures of RIPE NCC, ARIN, APNIC, and the other RIRs. We continuously stay up-to-date with each region's requirements.
Technical competence and transparency — Our team has deep expertise in Internet number resource management. We maintain open and transparent processes, providing evidence-based analyses and reports to relevant stakeholders.
Responsible transaction execution — We engage in direct acquisition and intermediary services only when appropriate, ensuring all transactions are registry-compliant, technically sound, and serve legitimate operational or governance objectives. We avoid speculation and arbitrage.
Long-term sustainability — We prioritize long-term solutions, reducing risks associated with legacy resources (such as inaccurate data or unmanaged networks) and ensuring that these Internet assets are secured for future generations.
