Sell IPv4 addresses
Sell IPv4 addresses with a clear sale proposal
Submit the IPv4 address blocks you want to sell and their registry. Target net proceeds and availability are optional. Review a sale proposal before committing; holder authority and transfer eligibility are checked before signing. After submission, keep your request code and private tracking link to follow the review.
- Resources to sell
- A specific IPv4 prefix the registered holder is authorized to transfer under the applicable RIR path.
- What buyers review
- Block size and scope, registry eligibility, routing status, dated reputation evidence, and proposed terms.
- Platform boundary
- i.lease supports listings, buyer-demand discovery, offers, and administrative coordination. It does not guarantee title, approval, price, timing, or completion and is not an escrow, trust, or custody provider.
Seller decision brief
Sell IPv4 by verified authority, net proceeds, and handover terms
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
- State exact prefixes, registered holder, current use, and signatory authority. A listing does not establish title or transferability.
- 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
- Agree verification milestones, payment and transfer sequence, route changes, reputation evidence, timing, and what proves completion. No price, approval, or timeline is guaranteed.
Transfer eligibility
Can you sell IPv4 addresses?
Eligible IPv4 address space can be transferred to another organization when the registered holder, the recipient, and the applicable Regional Internet Registry (RIR) satisfy the current transfer policy. Agreeing a price or publishing a listing does not by itself change the registry record.
- 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
- Share dated blacklist, abuse, routing, and geolocation observations. Historical evidence cannot guarantee future acceptance.
- 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
This is an operational comparison, not a valuation, tax, legal, or investment recommendation. Review the consequences for your organization and the applicable registry.
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
- Buyer matching, documentation, compliance review, and RIR processing all affect completion. No fixed timeline is guaranteed.
- 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.
From request to registry transfer
How to sell IPv4 addresses through an RIR transfer
i.lease can support discovery and administrative coordination, but the seller, buyer, compliance reviewers, and relevant RIR each retain their own responsibilities.
- 01
Submit your sale target
Submit exact prefixes and their RIR; target net proceeds and availability are optional. No account or public listing is needed first. Keep the request code and private tracking link returned after submission.
- 02
Review the sale proposal
Follow request updates and compare seller net proceeds, fees, resource confirmation, validity and next steps. Reference estimates or proposals awaiting sourcing are not executable quotes.
- 03
Review internally, then express interest
Share a read-only proposal or download a copy for internal review. Check the current version and validity before accepting; acceptance records interest and does not authorize signing or payment.
- 04
Complete the linked transaction
Once a transaction is linked, use its workspace for company authorization, signing, payment and transfer steps. The responsible parties verify holder authority, transfer eligibility and agreed completion and settlement evidence.
Seller questions
From sale request to transfer
Understand what to submit, how proposals are assessed and the limits of a sale. Registry policy and professional advice remain authoritative for your transaction.
What do I need to request an IPv4 sale proposal?
Enter the exact IPv4 prefixes and their RIR, then your name and email. Target net proceeds, availability, company and phone are optional. You do not need an account or public listing to submit. A successful submission returns a request code and private tracking link; it does not confirm a price, buyer or transfer eligibility.
How much can I get when I sell an IPv4 address block?
There is no guaranteed price. Block size, registry status, transfer eligibility, routing history, current reputation evidence, buyer demand, and negotiated terms can all affect an offer.
Can an IPv4 address block be sold?
A transfer may be permitted when the holder has authority and the applicable RIR policies, documentation requirements, and legal obligations are satisfied. Sellers should obtain their own legal and tax advice.
How long does an IPv4 sale take?
There is no guaranteed timeline. Counterparty review, documentation, compliance checks, registry policy, and RIR processing can all affect completion or approval.
What does i.lease do during a sale?
i.lease provides marketplace and administrative coordination services. It does not warrant ownership, authority, transferability, registry approval, price, timing, or transaction success, and it is not an escrow, trust, or custody provider.
Start a seller request
