IPv4 Leasing in 2026: How It Works, What It Costs, and When It's Worth It

IPv4 addresses are a finite resource. The five regional internet registries (RIPE, ARIN, APNIC, LACNIC, AFRINIC) ran out of fresh /8 blocks years ago, and the secondary market is now where almost all IPv4 trades happen. With purchase prices for a /24 in 2026 sitting in the $40–$60 per IP range, many businesses turn to IPv4 leasing to avoid the capital expense.

This guide explains how IPv4 leasing works, what it costs, when leasing makes sense versus buying, and how to avoid the traps.

Why Is IPv4 So Expensive?

The IPv4 address space contains only ~4.3 billion addresses, of which roughly 600 million are reserved (private, multicast, loopback, etc.). With over 5 billion internet users and exponentially more devices, scarcity is structural — not a temporary blip.

Demand keeps rising because:

• Cloud and hosting expansion still requires public IPv4 for legacy compatibility.
• Many networks haven't deployed IPv6 yet (or only partially).
• Some content (older devices, enterprise VPNs, certain APIs) still requires IPv4 reachability.
• Regulatory and operational habits favor stable, well-known IPv4 prefixes.

The result: per-IP prices have grown roughly 10x since 2018 and continue to rise.

What Is IPv4 Leasing?

IPv4 leasing is a contract under which the legal holder of an IP block (the "lessor") allows another party (the "lessee") to use those addresses for a fee, typically per IP per month. The lessor retains ownership; the lessee gets the right to announce and use the prefix.

Leasing has become a standard practice and is recognized by all five RIRs through Letters of Authorization (LOAs) and registry-specific transfer or assignment policies.

How an IPv4 Lease Works (Step by Step)

1. You choose a broker or lessor — companies like IPv4.Global, Heficed, IPXO, and Prefix Broker dominate the lease market.
2. You sign a lease agreement — usually 12 months minimum, often longer.
3. The lessor issues a Letter of Authorization (LOA) — a signed document confirming you may announce the prefix.
4. The RIR record is updated — typically the registry shows the prefix as assigned to or in use by your organization, depending on the policy.
5. You sign an RPKI ROA for your ASN (or the lessor signs one authorizing your ASN).
6. You announce the prefix via BGP from your network.
7. You pay monthly for the duration of the lease.

How Much Does IPv4 Leasing Cost in 2026?

Lease prices are set as monthly fees per IP. Typical 2026 rates:

• $0.40–$0.65 per IP per month for clean, large blocks (/24 to /22).
• $0.30–$0.50 per IP per month for /20 and larger blocks.
• Premium pricing for blocks with strong reputation, no historical abuse, or specific RIR jurisdictions.
• Additional fees for setup, RPKI signing, or transfer.

For a /24 (256 addresses), expect roughly $100–$160 per month.

Lease vs Buy: How to Decide

Math at 2026 prices:

• Buy a /24: ~$50/IP × 256 = $12,800 capex (one-time).
• Lease a /24: ~$0.50/IP/month × 256 = $128/month, or $1,536/year.

Pure economics: leasing breaks even with buying after about 8 years. If you'll need the IPs for less time, leasing wins. If you'll need them for longer (and IPv4 prices keep rising), buying wins.

Lease Makes Sense When:

• You need IPs now and don't have capex budget.
• Your need may be temporary (a project, a migration, a launch period).
• You want flexibility to expand/shrink without a secondary-market sale.
• You're testing a new region or product line.
• Your accounting prefers opex over capex.

Buy Makes Sense When:

• You'll keep the IPs for 5+ years.
• You believe IPv4 prices will continue to rise (history says yes).
• You want full control and an asset on the balance sheet.
• You qualify for direct allocation/transfer through your RIR.

What to Watch Out For

• Reputation. Leased IPs may have been used for spam, scanning, or malware. Always check Spamhaus, Project Honey Pot, IPVoid, and major RBLs before committing.
• RPKI conflicts. The lessor must sign ROAs for your ASN, or the prefix will be RPKI-invalid (and dropped by many networks).
• Term length. 12 months is typical. Read the renewal and termination clauses.
• Geographic restrictions. Some lease contracts limit where the prefix can be announced (e.g., RIPE jurisdiction only).
• Sub-allocation rights. Can you sublease parts of the block to your own customers? If you're a hosting provider, this matters.
• Exit plan. Renumbering away from leased space is painful — plan how you'd migrate if the lease ends.

How to Vet Leased IPs Before Use

1. Run the prefix through abuse databases — Spamhaus DROP, Spamhaus EDROP, Barracuda RBL, etc.
2. Check WHOIS history — has the prefix been transferred recently? What's it been used for?
3. Test reachability — confirm major networks accept the prefix without filtering.
4. Verify RPKI — once announced, validate your ROA with public RPKI validators.
5. Monitor for delisting issues — if blocks are listed somewhere, request delisting before production use.

The IPv6 Question

Every conversation about IPv4 leasing should include the IPv6 question. IPv6 is free, abundant (340 undecillion addresses), and supported by virtually all modern infrastructure. If you're starting fresh in 2026, deploy IPv6 for everything you can, and use IPv4 only where required.

Practical hybrid: IPv6-only internal networks with NAT64/DNS64 or 464XLAT for IPv4 reachability. This minimizes how much IPv4 you need to lease.

IPv4 at Noded

Noded includes IPv4 addresses on every bare metal and VPS service, and we offer additional clean IPv4 blocks for customers who need more than the included space. Every server also gets an IPv6 /64 — putting you on the right path for the future. Combined with our IPAM, you can manage allocations, reverse DNS, and BGP announcements from one place.

Frequently Asked Questions

Are leased IPs as good as owned IPs?

Functionally, yes — they route the same way and look the same to remote networks. The differences are legal (you don't own them) and contractual (you must renew).

Can I get RPKI on leased IPs?

Yes — the legal holder of the prefix signs a ROA authorizing your ASN. Always confirm RPKI is included before signing a lease.

What happens if the lessor goes out of business?

Reputable brokers escrow the underlying allocation or have arrangements ensuring continuity. Less reputable ones can leave you scrambling. Stick with established, vetted providers.

Can I lease less than a /24?

Yes — many providers lease /28s, /29s, or even single IPs for retail customers. Note that /24 is the smallest globally routable IPv4 prefix on the public internet.

Do I need my own ASN to lease IPv4?

Only if you'll announce the prefix yourself. If your hosting provider announces it on your behalf, you don't need an ASN.
