Why Buying IPv4 Addresses Makes More Sense Than Leasing in 2026

Organisations still running IPv4-dependent infrastructure face a straightforward cost question: pay recurring charges to lease addresses indefinitely, or acquire them outright and control costs over the long term. For most businesses with a stable, multi-year need for public IPv4 space, the maths increasingly favours ownership.

Cloud providers now charge for public IPv4 addresses that were previously included in standard pricing. Those charges are per address, per hour, and compound across all addresses in a deployment. At scale, that recurring expense adds up to a significant annual line item with no end date and no asset to show for it.

For organisations ready to move from recurring costs to a fixed acquisition, the first step is to buy IP addresses through a vetted marketplace that handles blacklist verification, registry documentation, and the transfer process from start to finish. IPv4Connect is trusted by over 3,000 companies worldwide, holds a 4.8-star rating across more than 200 reviews, and operates as an official transfer facilitator across ARIN, RIPE, APNIC, and LACNIC regions.

What Leasing Actually Costs Over Time

Leasing IPv4 addresses looks affordable every month. The problem is that the monthly cost never stops, and it compounds as deployments grow.

Cloud-based IPv4 charges now run at $0.005 per hour per address, which translates to $43.80 per address annually. For an organisation running 256 addresses, that is over $11,000 per year. For 1,024 addresses, the annual bill exceeds $44,000. These charges apply regardless of whether the addresses are actively in use, and they sit on top of all other infrastructure costs without building any equity or reducing over time.

Third-party lease arrangements add a different set of risks. The lessee does not control routing security, meaning ROA configuration and IRR records remain under the lessor's authority. Abuse handling and letter of authorisation issuance sit with the lessor as well. If the relationship ends or the lessor changes their policies, the lessee has no guaranteed continuity of access. For mission-critical infrastructure, that dependency is a risk that recurring lease payments do not offset.

The Case for Ownership

Buying IPv4 addresses transfers registry control to the purchasing organisation. The buyer becomes the holder of record at the relevant regional internet registry, whether that is ARIN, RIPE NCC, or APNIC. From that point, the organisation controls routing security through its own RPKI configuration, manages its own ROA and IRR records, handles reverse DNS, and publishes its own geofeed data.

That level of control matters operationally. Blacklist remediation is faster when your team manages the records directly. Geolocation corrections go through your own registry objects rather than waiting on a lessor. Route origin validation is under your governance rather than dependent on a third party maintaining their configurations correctly.

The financial case is equally clear for steady-state deployments. At current market rates, purchased IPv4 space can break even within 24 to 36 months compared to ongoing cloud or lease charges, depending on the size of the block and the per-address cost of the alternative. After that point, the organisation is no longer paying for access it does not own. The space can also be sub-leased if capacity exceeds current need, or sold if requirements change, making it a liquid asset rather than a sunk cost.

What the Current Market Looks Like

2026 represents a more accessible entry point for buyers than the previous few years. Larger blocks have seen meaningful price reductions, with /16 space trading at lower per-IP prices than smaller blocks. /24 blocks, which represent the minimum transferable unit under ARIN policy, continue to trade at a slight premium relative to larger blocks due to demand from smaller organisations entering the market.

Reputation quality remains the most important variable beyond price. Industry data consistently shows that 50 to 60 percent of IP addresses on the secondary market carry some form of blacklist history. Buying a discounted block that arrives listed on Spamhaus, Cisco Talos, or other major reputation providers creates remediation work that can take weeks and affects email deliverability, partner allowlists, and customer-facing services in the meantime. The price difference between a clean block and a compromised one rarely reflects the true cost of cleaning up.

What to Verify Before Buying

A block that prices well on paper can still create significant problems after transfer if the diligence process is skipped or compressed.

Reputation and blacklist status. Run the sample IPs through Spamhaus ZEN and Cisco Talos for blacklist status, and check AbuseIPDB for abuse report history before signing anything. Include blacklist-free representations in the transfer agreement and establish clear remediation obligations if issues emerge post-transfer.

Registry record integrity. Use RDAP or whois to confirm the current holder of record, verify that the selling entity matches the registry record, and check for any active disputes or encumbrances on the block.

Existing ROA and routing records. Old route origin authorisations and IRR objects from previous holders can cause routing validation failures after you take control. Require the seller to remove these before funds are released.

Geolocation data. Blocks that have moved between regions or operators often carry stale geolocation records. If users are routed to the wrong country based on the IP, it affects licensing, content delivery, and user experience. Publishing an RFC 8805 geofeed on day one and submitting corrections to major providers is part of a clean transfer, not an afterthought.

How the Transfer Process Works

RIR transfers follow a defined sequence, and the timeline varies by registry.

ARIN charges a non-refundable $500 processing fee from the source and a recipient fee scaled to block size, starting at $187.50 for a /24. ARIN recipients must demonstrate how the resources will be used within 24 months, which requires preparation before shopping for space.

RIPE NCC in-region transfers carry no transfer fee and can be completed in one to two business days once documentation is accepted. RIPE does impose a holding period on received space during which the block cannot be transferred again.

APNIC charges the recipient 20 per cent of the applicable annual fee for resources transferred. APNIC buyers should confirm LIR membership or sponsoring LIR status and have corporate documents ready before initiating.

Working with a marketplace that manages documentation, registry submission, and post-close routing tasks removes the friction from each of these steps. IPv4Connect handles the entire transfer process for buyers, providing free blacklist reports on over 100 global blacklists for every subnet in its inventory, and completing fully managed transfers within two to three weeks. With over 1,000 clients served across more than 60 countries, and buy-now pricing that removes the uncertainty of auction formats, the platform is designed to get organisations from agreement to usable space without the administrative overhead of direct deals.

Ownership as a Long-Term Infrastructure Decision

The organisations that benefit most from buying IPv4 are those treating it as a multi-year infrastructure decision rather than a short-term fix. If the need for stable public IPv4 extends beyond two years, recurring lease or cloud charges will consistently outpace the one-time acquisition cost of owning the equivalent space.

The secondary market now offers clean blocks at accessible price points, established transfer frameworks across all major registries, and specialist marketplaces that handle the compliance and routing work that used to make direct purchases difficult for first-time buyers.

For organisations ready to stop paying for access to infrastructure they do not own, the case for acquisition in 2026 is stronger than it has been in years.
