Your IPv4 sale
Turn your IPv4 blocks into your next opportunity
Selling a block is a registry transfer and a commercial handover. Confirm what you control, compare sale proceeds with retained lease obligations, and agree evidence and settlement conditions before committing.
- Confirm the resource
- Send the prefixes, registered holder and current usage so we can prepare your sale together.
- Compare net outcomes
- Separate target net proceeds from buyer price, taxes, registry and transfer fees, settlement costs, and any continuing routing or support obligations.
- Verify the transfer path
- Check source and recipient RIR policy, holding and size rules, recipient eligibility, and required evidence including registry, RPKI, IRR, LOA, routing, and abuse records.
- Set handover conditions
- Plan the payment milestones, registry transfer and routing handover with the buyer and our team.
Transfer eligibility
Can you sell IPv4 addresses?
Sell eligible IPv4 blocks through a registry transfer. We help you bring together the holder records, buyer requirements and transfer documents.
- Registered holder
- Confirm the exact prefix, current registry record, authorized signatory, and whether the resource is free of dispute or transfer restrictions.
- Eligible transfer path
- Check whether the source and recipient qualify for an intra-RIR or inter-RIR transfer, including minimum size, holding period, documentation, and fees.
- Verified completion
- Keep commercial settlement conditional on the agreed evidence, then independently verify the registry update, routing handover, RPKI and IRR changes, and operational acceptance.
Seller readiness
What a buyer and registry will need to evaluate
Start with your exact IPv4 prefixes, registry and contact details; target net proceeds and availability are optional. You can submit without a public listing or a complete evidence dossier. Before signing, review the following evidence and conditions with the relevant parties.
- Authority and holder record
- Identify the registered holder, authorized signatory, and any organization or account that must approve the transfer.
- Registry eligibility
- Confirm the current RIR, applicable transfer path, waiting periods, documentation, fees, and policy restrictions.
- Block scope
- State the exact prefixes, block size, aggregation or split constraints, and whether any addresses remain in use.
- Routing handover
- Document BGP origin, RPKI, IRR, LOA, rDNS, geofeed, and the sequence for authorized changes.
- Reputation evidence
- Bring your blacklist, abuse, routing and geolocation history together so buyers can assess the block.
- Commercial conditions
- Define the requested price, currency, taxes, verification conditions, settlement milestones, and responsibility for third-party costs.
Choose the operating model
Sell once or retain the resource and lease it
Choose a sale to release capital, or keep your addresses and build recurring lease income. We help you explore both routes.
Commercial model
- Sell IPv4
- A negotiated one-time sale, subject to the agreed conditions and completion path.
- Lease IPv4
- Recurring charges under a lease contract; actual revenue depends on utilization, term, costs, and performance.
Holder outcome
- Sell IPv4
- A completed, registry-approved transfer changes the registered holder or sponsoring relationship as the applicable policy provides.
- Lease IPv4
- The holder retains the resource while granting defined use and routing rights under contract.
Ongoing operations
- Sell IPv4
- Responsibilities move only as agreed and verified; the seller remains responsible until the relevant handover is complete.
- Lease IPv4
- The holder continues contract, routing-authority, registry, reputation, abuse, and lessee coordination.
Timing
- Sell IPv4
- Plan the sale around buyer matching, document preparation and registry processing.
- Lease IPv4
- Onboarding and activation depend on contract, technical readiness, authorization, and counterparty action.
Future optionality
- Sell IPv4
- The seller gives up future control or use once the transfer is completed.
- Lease IPv4
- The resource is retained, but future use and availability remain constrained by active contracts and operating obligations.
