Sell Your IPv4 Block

Sell IPv4 addresses through a broker-supported process with valuation, buyer screening, escrow and RIR coordination. InterLIR Global helps network owners prepare transferable address space, connect with qualified buyers and complete the transaction through the relevant registry.

Selling an IPv4 block converts unused address space into a one-time payout through a permanent ownership transfer. A managed sale can combine valuation, buyer screening, escrow and RIR coordination so the seller can prepare the resource, reach qualified counterparties and complete the transaction under documented commercial and registry conditions.

There are no upfront listing fees. Brokerage commission is charged when a transaction is completed and depends on block size. The IPv4 selling service supports an IPv4 block sale with valuation, buyer screening and escrow. IPv4 broker sale support coordinates the transaction, while an IPv4 escrow sale structure helps align payment with completion of the RIR transfer.

What affects the value of an IPv4 block?

An IPv4 sale valuation is based on the specific resource rather than one fixed price per address. Important factors include:

• prefix size;
• RIR region and transfer eligibility;
• routing and reputation history;
• geolocation;
• documentation quality;
• buyer demand.

Preparing WHOIS, routing, RPKI/ROA and ownership records before listing can reduce delays during due diligence. Owners ready to sell IPv4 block resources can use this preparation to make the asset easier for qualified buyers to assess.

How does the IPv4 selling process work?

The sale moves from resource review to RIR transfer in five stages:

1. Provide the prefix and ownership information.
2. Receive a valuation and transaction review.
3. Offer the block to qualified buyers.
4. Agree on transaction conditions and escrow.
5. Complete the RIR transfer and receive the payout.

Funds are released according to the agreed transaction conditions after the transfer is completed.

What brokerage commission applies?

The commission decreases as block size increases:

• /24 — 12%;
• /23 — 10%;
• /22 — 8%;
• /21–/19 — 6%;
• /18–/17 — 5%;
• /16 and larger — 4%.

The final transaction value and any additional requirements depend on the specific resource and transfer structure.

Transfer timing depends on the registry and the readiness of ownership and technical records. Preparing WHOIS data, routing objects and supporting documents before buyer due diligence can shorten avoidable delays and make the block easier to evaluate.

If recurring income is preferable to a permanent sale, owners can lease out IPv4 addresses instead and retain ownership while the block is used by a tenant.

A preliminary valuation helps determine whether the resource is commercially ready before it is presented to buyers. The review can take into account prefix size, registry region, transfer status and technical history so the seller enters negotiations with clearer expectations about the transaction.

Request an IPv4 valuation

For a sale, provide the prefix size, RIR, ownership status and routing information to InterLIR Global. The resource can then be evaluated for transfer readiness and buyer demand before a transaction structure is agreed.
