How to sell IPv4 addresses?

Turn your IPv4 addresses into cash for growth

Sell IPv4 directly to LARUS: share your address blocks, get a cash offer, then complete the transfer and receive payment. You deal with the buyer from the start, without finding a broker or waiting for a marketplace to match your listing. If your network still needs the addresses, discuss sale and leaseback alongside your offer.

An unused block could fund a new deployment, extra network capacity or your next business priority. IPv4 sales move registered address space from one holder to another through a registry transfer. LARUS brings the buyer, commercial discussion and transfer coordination together so you can focus on what the proceeds will do for your business.

Start with the capacity you no longer need, whether it came from consolidation, a retired service or a network redesign. You can also release capital from addresses still in use through a sale-and-leaseback arrangement. The useful question is how much cash you want to unlock and which services must keep running.

How to sell IPv4 to LARUS in three steps

1. Share your blocks and your plans

Send the exact prefixes, the registry shown in the records and your preferred timing. Tell us whether the blocks are unused, currently serving customers or partly needed after the sale. A clear starting point makes the offer more useful and lets the transfer plan fit your business.

2. Get an offer from the direct buyer

LARUS buys IPv4 directly. You can discuss the cash offer, transfer timing and any capacity you want to lease back with the same company. There is no broker to appoint and no separate buyer search to manage.

Compare the whole outcome: the amount you receive, the payment milestone, who coordinates the transfer and how your active services stay connected. Agreeing these details together gives your finance and network teams one shared plan.

3. Complete the transfer and put the cash to work

The registry records, payment and network handover each have a place in the transaction. LARUS coordinates the purchase and transfer with you; your network team schedules any routing changes around the services your customers use.

The sale page sets out the direct route: complete the transfer and get paid directly by LARUS. Establish the payment milestone with the offer so your business can plan around the proceeds. An agreed sale price, a signed document and a completed registry transfer are different milestones.

What are your IPv4 addresses worth?

A current offer for your actual blocks is more useful than an old price chart. Block size, registry, transfer route, address history, buyer demand and readiness all shape the offer. A fresh offer helps you decide what the capital can do for your business today.

Share the prefixes you are considering, even if you are still deciding between selling everything and retaining part of the capacity. Include any known reputation issues and the date the blocks can be handed over. That lets the commercial conversation start with your real inventory.

Use our IPv4 pricing and market statistics for market context. Lease rates and purchase offers are different measures: ask for a direct purchase offer to value a sale. For a broader comparison of cash and rental income, read selling versus leasing IPv4 addresses.

Release capital while keeping the capacity you need

Selling surplus blocks gives you cash from resources your business no longer uses. Leasing them out creates recurring income while keeping you involved in the address operation. Sale and leaseback offers another path: sell to LARUS, then lease back the addresses your network still needs.

Keep customer services at the centre of the sale

Stable addresses matter to APIs, customer allowlists, remote access, email and hosted services. Tell LARUS which prefixes must remain in service before the transaction is planned. With sale and leaseback, the commercial discussion includes both your cash proceeds and continued use of the agreed capacity, rather than leaving renumbering as a problem to solve afterwards.

That also changes who carries the ongoing registry-side burden. LARUS is a first-party IPv4 operator built around address continuity, rather than a marketplace that only introduces counterparties. Explore LARUS IPv4 Continuity and Unlimited IPv4 for the network you want to keep growing.

The continuity model connects Cloud Innovation's court-recognized AFRINIC shareholder position with its exclusive operating mandate to LARUS. That brings the institutional foundation and the team delivering your ongoing capacity into one operating relationship.

Lu Heng explains the distinction in his Notes on registry risk and LARUS Continuity and the broker and registry-risk question. The practical seller benefit is a direct buyer and a continuing operating relationship for the addresses you keep using.

Describe the block with CIDR, not address classes

Use the exact network prefix and length, such as a /24 or /22, when requesting an offer. Historical labels such as Class A, B and C do not identify the specific block you want to sell. CIDR makes the size clear to both the buyer and the engineers preparing the handover.

Common IPv4 block sizes: total addresses in each prefix

CIDR prefix length	Total addresses
/24	256
/23	512
/22	1,024
/21	2,048
/20	4,096
/19	8,192
/18	16,384
/17	32,768
/16	65,536

These are total address counts, not a promise that every address is a usable host in every subnet design. RFC 4632 explains CIDR notation. If you want to sell part of a larger block, identify the exact smaller prefixes and the capacity that will remain in use.

Prepare once for a smoother offer and transfer

The following details help move the sale forward and keep your technical team out of repeated information requests. Start with what you already know; use the discussion with LARUS to work through the block's transfer path.

Find the registry and the exact resource record

WHOIS or RDAP identifies the registry and organisation associated with a block. The IANA number-resource overview lists the regional registries. Your resource record, rather than your office location alone, tells you where to start.

Registry transfer processes differ. Use the relevant registry's current transfer instructions for the administrative steps; LARUS can discuss how the purchase fits that route. The retained starting references include ARIN's transfer guide, RIPE NCC's transfer information and APNIC's transfer information.

An intra-RIR transfer stays within one registry; an inter-RIR transfer crosses between registries. Identifying that distinction early helps both sides schedule the right process instead of discovering another registry step at handover.

Make the records easy to follow

Keep the registered organisation name and a current resource contact alongside your prefix list. If the business has changed its name, merged or acquired the addresses through another company, note that history so the resource record and today's seller can be connected promptly.

Flag any recent transfer, allocation or ongoing registry request. This helps establish the transfer route and schedule while the commercial discussion moves forward. Outdated contacts are often simpler to resolve early; our guide to WHOIS and RDAP records in IPv4 transfers explains the practical checks.

Accurate records also help the buyer operate the addresses after completion. They connect the resource to the right contacts, while your routing and DNS plan keeps the technical handover aligned with the transaction.

Share the address history

Note previous use, known blocklist entries, active customers and any remediation already completed. A clear history gives the buyer a better picture of deployment readiness. Reputation checks complement the registry record; neither replaces the other.

Keep a compact sale file

Bring together the prefixes, organisation and contact details, registry records, relevant company-name changes, current use and intended handover date. Add the capacity you want to retain or lease back. This gives your commercial and technical contacts a shared reference for the sale.

Plan the handover around customer continuity

Before a block changes hands, map where it is used. IPAM records, BGP announcements, RPKI authorisations, IRR objects, reverse DNS and customer allowlists each describe a different dependency. A block that looks unused in an inventory may still support an API, VPN or monitoring endpoint.

Coordinate routing and records together

• BGP: agree who announces the prefixes and when the origin or upstream changes.
• RPKI: align route origin authorisations with the intended origin ASN and prefix lengths.
• IRR: update route objects and routing-policy data used by upstream filters.
• DNS and reverse DNS: coordinate zone responsibility, records and any service migration.
• Customer dependencies: check allowlists, tunnels, mail services and monitoring with the teams that use them.

A registry transfer does not automatically change BGP or every downstream database. Keep working routes and authorisations in place until the coordinated handover is ready. For leaseback, plan continued service on the retained addresses from the outset, including who handles ongoing routing and record updates.

Questions sellers ask

Do I need an IPv4 broker?

No. You can sell directly to LARUS. Your offer and transfer discussion are with the buyer, without a separate broker or marketplace matching step.

Can I sell a /24 or part of a larger block?

A /24 contains 256 addresses. Send the exact prefix you want to sell, including any smaller portion of a larger holding, so LARUS can work through the purchase and transfer route with you. Prefix size and registry transfer eligibility are separate questions.

How long does selling IPv4 take?

Timing depends on the block's records, the registry transfer route and your handover plan. Dealing directly with LARUS removes the separate buyer-search step. Share your target date with the prefixes so the offer, payment milestone and network work can be planned together.

Can I sell the addresses and keep using them?

Yes—discuss sale and leaseback with LARUS. Include the prefixes and capacity your customers still rely on, so continued use is part of the sale plan from the beginning.

Should I wait for prices to rise?

Compare a current cash offer with what that capital could achieve in your business. A forecast is not a buyer, and a historical price is not an offer for your blocks. Our guide to selling unused IP addresses explores the commercial decision.

Does signing the sale change the network immediately?

No. The commercial agreement, registry transfer, payment and routing handover are coordinated milestones. Planning them together helps your finance team receive the proceeds and your network team keep customer services working.

Ready for your cash offer?

• Your exact IPv4 prefixes and registry.
• Whether each block is unused or currently serving customers.
• Your preferred sale and handover timing.
• Any addresses you want to keep using through leaseback.

Bring those details to LARUS for a direct IPv4 cash offer. Put your address value to work, remove the broker search and keep the capacity your business needs in the conversation from day one.
