Sell IPv4 address space
Sell IPv4 addresses with a transfer-ready listing
List an IPv4 address block for sale with the holder authority, RIR eligibility, routing records, dated reputation evidence, and commercial terms a buyer needs to review. i.lease provides marketplace and administrative coordination; the seller remains responsible for the transfer request and policy compliance.
- What you can list
- 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 readiness
What a buyer and registry will need to evaluate
A credible listing separates observed facts from promises. Assemble the current evidence before you discuss price or timing.
- 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.

The responsible parties submit required registry requests, complete authorized handover steps, and verify the agreed completion evidence.
Seller questions
What to confirm before listing
These answers describe the marketplace workflow and its limits. Registry policy and professional advice remain authoritative for your transaction.
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.
