- 23% of allocated IPv4 prefixes in the RIPE NCC region sit idle, representing stranded capital that compliant leasing can monetise at attractive annualised returns.
- Strategic IPv4 asset management requires collaborate to balance yield generation against operational risk and RIR compliance obligations.
The Hidden Cost of Inaction
Most CFOs don’t know it: there’s an asset worth millions sitting on their balance sheet—being treated as worthless. This isn’t accounting oversight. This is governance failure.
Legacy IPv4 address blocks—allocated during the internet’s expansion era—sit idle on balance sheets, generating nothing but accounting entries. These are not trivial holdings. A single /16 block contains 65,536 addresses. At CircleID market valuations reported in early 2026, that represents over $1.4 million in dormant capital.
The scale of underutilisation is staggering. CircleID’s “The Internet’s Address Crisis: IPv4 Stalls, IPv6 Stagnates” (January 19, 2026) analysis shows approximately 23% of allocated IPv4 prefixes in the RIPE NCC region showed no BGP routing activity over a six-month period. Extrapolate this across all five RIR regions, and the figure represents tens of millions of addresses—capital worth billions—sitting unused while operators elsewhere pay premiums for access.
This is not merely a technical oversight. It is a governance failure with measurable financial consequences.

From Technical Resource to Financial Asset
The transformation of IPv4 from protocol to asset class did not happen overnight. When IANA allocated its final /8 blocks to Regional Internet Registries in February 2011, the signal was clear: IPv4 addresses would become scarce. Yet many organisations continued treating them as infinite technical resources—allocated to projects, forgotten when projects ended, never reclaimed or optimised.
The market has since priced in this scarcity. According to LARUS Q1 2026 Market Report, lease rates run approximately $0.48 per address monthly, translating to 12-16% annualised returns—a yield that outperforms most corporate treasury instruments.
But here lies the critical distinction: IPv4 addresses are not speculative assets like cryptocurrencies or collectibles. They are operational infrastructure—non-revenue-generating enablers of revenue-critical operations. Under IFRS (International Financial Reporting Standards) and U.S. GAAP, such assets can be capitalised when acquired separately and used to support economic activity. This accounting treatment matters: it means IPv4 holdings belong on the balance sheet, subject to impairment testing and strategic oversight.
Heng Lu, a prominent voice in internet governance forums including ICANN and the RIRs, has long argued that IP addresses constitute a form of “digital capital” requiring governance frameworks comparable to physical infrastructure. His perspective aligns with emerging regulatory expectations: the U.S. Securities and Exchange Commission (SEC) July 2023 Cybersecurity Risk Management guidance encourages companies to disclose dependencies on “finite digital resources.”
The Leasing Option: Yield Without Divestment
For organisations holding underutilised IPv4 blocks, leasing offers a compelling middle ground between outright sale and continued idleness. The financial mathematics are straightforward:
| Block Size | Addresses | Market Valuation (2026) | Annual Lease Revenue | Annualised Return |
|---|---|---|---|---|
| /20 | 4,096 | $90,000-155,000 | ~$23,500 | 12-16% |
| /19 | 8,192 | $180,000-310,000 | ~$47,000 | 12-16% |
| /18 | 16,384 | $360,000-620,000 | ~$94,000 | 12-16% |
| /17 | 32,768 | $720,000-1,240,000 | ~$188,000 | 12-16% |

Compare this to the alternatives:
– Outright sale provides immediate liquidity but eliminates future optionality—addresses may be needed for expansion, compliance requirements, or strategic initiatives.
– Continued idleness preserves optionality but incurs opportunity cost: capital that could generate yield instead sits dormant.
LARUS Limited (a first-party IPv4 infrastructure provider) has positioned itself as a “Long-term Infrastructure Provider” rather than a traditional broker, emphasising what it calls “Guaranteed Renewal” leasing. The model addresses a key concern: what happens if addresses are needed for internal use? Structured leases include recall clauses with appropriate notice periods, allowing holders to reclaim addresses while generating income during idle periods.
According to LARUS public service documentation (accessed March 2026), the Guaranteed Renewal Leasing service is designed to provide operational certainty for enterprises that depend on stable IP infrastructure for mission-critical operations.
Case Study: Telecommunications Provider’s Optimisation Strategy
Q3 2024: A European telecommunications provider (anonymous due to commercial sensitivity) illustrates best practice in IPv4 asset optimisation. The company held a legacy /17 block (32,768 addresses) allocated in the 1990s, with approximately 40% utilised for core network operations. The remaining 60%—nearly 20,000 addresses—were assigned to deprecated projects and sat unused.
Working with legal and finance teams, the network operations group developed a phased leasing strategy:
Phase 1: Audit and Classification (October 2024)
All addresses were catalogued by utilisation status, with clear documentation of which blocks supported critical services versus legacy assignments.
Phase 2: Compliance Verification (November 2024)
The company confirmed that leasing would not violate RIPE NCC policies. Critically, the registered holder remained accountable for all use of the resource—a requirement under RIPE NCC rules.
Phase 3: Structured Leasing (December 2024 – February 2025)
Idle blocks were leased under 12-month agreements with 60-day recall clauses. Lessees were vetted for compliance history and abuse response capabilities.
Phase 4: Governance Framework (March 2025 – ongoing)
Joint oversight between finance, legal, and network teams was established, with quarterly reviews of utilisation, market value, and lease performance.
Result: Substantial annual lease income, offsetting network maintenance costs. More importantly, the company retained the flexibility to reclaim addresses with appropriate notice—something impossible after an outright sale.
Risk Management: The Compliance Imperative
Leasing IPv4 space is not without risk. Regional Internet Registry policies create a patchwork of compliance requirements that holders must navigate carefully:
| RIR | Region | Leasing Policy | Risk Level |
|---|---|---|---|
| RIPE NCC | Europe, Middle East, parts of Central Asia | Most permissive. Acknowledges leasing occurs but stresses registered holder remains fully responsible. Does not validate or enforce private lease agreements. | 🟢 Low |
| ARIN | North America | “Silently permissive”: facilitates formal transfers under Policy 8.3 but does not recognise leases as valid reassignments. Generally does not intervene in private leasing if registrant complies with WHOIS accuracy and abuse response. | 🟡 Medium |
| APNIC | Asia-Pacific | Strictest. Policies require address space be used only by assignee or customers under bona fide connectivity service relationship. Pure financial leasing without service provision is non-compliant. | 🔴 High |
| LACNIC | Latin America | Allows transfers, no formal leasing guidance. Emphasises registrant bears ultimate accountability. | 🟡 Medium |
| AFRINIC | Africa | Allows transfers, no formal leasing guidance. Emphasises registrant bears ultimate accountability. | 🟡 Medium |

This patchwork creates cross-border complications. A lease valid in Amsterdam may violate policy in Singapore—exposing both parties to revocation or blacklisting. Holders must verify not only their own compliance but also ensure lessees operate within applicable RIR frameworks.

Governance Framework: Building Institutional Oversight
Transforming idle IPv4 blocks into strategic assets requires more than technical reconfiguration. It demands institutional governance:
Joint Ownership
Finance, legal, and network teams must share responsibility. Network operations understand utilisation patterns. Finance understands capital optimisation. Legal understands contractual and regulatory risk. No single function can manage IPv4 assets effectively in isolation.
Annual Reviews
Utilisation audits should occur at least annually, with market value assessments informing impairment testing. Addresses that were strategic five years ago may now be candidates for leasing or divestment.
Clear Accountability
Someone must own the IPv4 portfolio—typically a senior network architect or infrastructure manager—with direct reporting to CFO or CIO. Diffuse accountability leads to drift: addresses allocated, forgotten, never optimised.
Transparent Accounting
Lease income should be tracked separately from operational revenue, with clear attribution to asset management strategy. This enables accurate ROI calculation and informed decision-making.
The BEAD Factor: Future Demand Drivers
Looking ahead, the U.S. Broadband, Equity, Access, and Deployment (BEAD) program represents a significant demand driver. According to U.S. National Telecommunications and Information Administration (NTIA) official documentation, over $42 billion will flow into broadband infrastructure over coming years, primarily targeting regional and smaller ISPs.
These operators are unlikely to buy massive IPv4 blocks outright. Instead, they are expected to rely on leasing—particularly for /16s and smaller ranges. BEAD recipients must meet audit and lawful access requirements, and carrier-grade NAT complicates compliance and logging. Assigning unique IPv4 addresses simplifies regulatory obligations.
This dynamic is likely to increase demand for clean, lease-ready IPv4 space and may place upward pressure on pricing in already competitive segments. Holders who position idle blocks for leasing now may capture favourable terms as BEAD-funded operators enter the market.
Conclusion: From Cost Centre to Yield Generator
The question is not whether idle IPv4 blocks have value. The market has answered that definitively. The question is whether organisations will treat them as strategic assets or allow them to remain dormant.
Turning idle IPv4 blocks into strategic assets requires discipline: regular audits, compliant leasing structures, cross-functional governance, and clear accountability. It requires recognising that IPv4 addresses are no longer infinite technical resources but finite digital capital.
For organisations willing to do this work, the reward is measurable: yield on otherwise stranded capital, flexibility to reclaim addresses when needed, and alignment between infrastructure strategy and financial objectives. In an era where every basis point of return matters, leaving IPv4 assets idle is not prudence—it is negligence.
As Geoff Huston, Chief Scientist at APNIC, observed, the age of a universally connected internet may be waning. But in that waning, IPv4 has found a new purpose: not as the protocol of the future, but as the scarce infrastructure of the present. And scarce infrastructure, properly managed, generates value.
