About IPv4.online | IPv4 Broker & Marketplace

We run a dedicated IPv4 marketplace and are a RIPE NCC broker. Our job is to make it straightforward for businesses and network owners to get the IPv4 space they need—or to monetize blocks they no longer use—without the usual fragmentation and risk. Whether you want to buy, rent, lease, or lease out IPv4, we provide one platform, clear process, and support across RIPE, ARIN, LACNIC, and APNIC.

Who we are

IPv4.online exists because the IPv4 secondary market is still scattered across brokers, forums, and opaque processes. We combine a marketplace where you can browse and compare listings with broker services that handle RIR transfers, due diligence, and paperwork. We work with LIRs in every major region so that whether you need a /24 or a /16, you get a consistent, compliant path from quote to delivery.

Marketplace — Listings from multiple suppliers; browse, compare, and transact in one place.
Broker — We facilitate LIR-backed RIR transfers and guide you through LOA, due diligence, and each step of the process.
Self-service and support — Get a quote, list your block, or get help from our team when you need it.

What we do

We help with the full range of IPv4 transactions:

Buy IPv4 — Full ownership via RIR transfer. We source blocks from real network owners, support escrow for large deals, and guide you through how to buy IPv4 from quote to registration.
Rent and lease IPv4 — Short- or longer-term use without upfront purchase. Flexible terms, clear pricing, and automated LOA so you can scale without long lock-ins.
Lease out or sell IPv4 — Monetize unused space. We help you list blocks, find counterparties, and complete transfers or lease agreements with proper due diligence.

We operate across RIPE, ARIN, LACNIC, and APNIC. Block sizes from /24 up to /16 are available; we help you match size, region, and use case so you get the right option for hosting, cloud, enterprise, or other needs.

How we work: due diligence and trust

We take due diligence and LOA (Letter of Authorization) seriously. Every transfer we facilitate follows RIR rules and is backed by LIRs we work with. For large purchases we use escrow: funds are held by a third party until the RIR transfer completes, so both buyer and seller are protected.

We also care about block history and reputation. A clean block has no significant abuse or blocklist issues that would hurt deliverability or reputation. We help assess history and guide you before you commit, so you know what you’re getting.

RIR-compliant transfers — LIR-backed process in line with RIPE, ARIN, LACNIC, and APNIC requirements.
