- IPv4 adoption remains around 60% globally, meaning most internet traffic still depends on address space acquired decades ago.
- Operators who secured address blocks in the 2010s now hold assets worth significantly more than their acquisition cost, creating structural advantages that latecomers cannot easily replicate.
IPv4 addresses have evolved from technical identifiers into scarce digital assets, fundamentally reshaping how network operators approach infrastructure planning. What began as a technical coordination problem has become a strategic business consideration that separates competitive providers from those struggling with higher costs and limited flexibility.
But what does this mean for networks that missed the early IPv4 boom? The answer reveals a broader pattern in internet infrastructure: scarcity creates value, and value rewards those who plan ahead.
What happened: Scarcity reshaped infrastructure
For much of the internet’s early history, IP addresses were treated as administrative allocations rather than economic assets. Internet service providers requested address blocks based on projected growth, often without considering long-term value.
The turning point came in 2011 when IANA exhausted its IPv4 pool, prompting regional internet registries to implement transfer policies. APNIC introduced rationing measures, ARIN established a transfer market, and RIPE developed policies that created the foundation for a secondary market. These changes transformed IPv4 addresses from free administrative resources into tradable commodities with measurable market value.
BTW has observed that this transformation caught many operators off guard. Networks that once viewed address space as a technical afterthought now face strategic decisions with significant financial implications.
The cost of inaction
The divergence between early planners and late movers has created stark competitive differences.
Some regional ISPs delayed IPv4 planning until recently, assuming IPv6 adoption would eliminate the need for additional IPv4 space. By the time carrier-grade NAT started causing customer complaints about gaming and video conferencing quality, the leasing market had already matured. These networks now face recurring operational expenses that could have been avoided with earlier strategic planning.
The reality is that IPv6 adoption remains around 40% globally, meaning 60% of traffic still requires IPv4 connectivity. This gap isn’t closing as quickly as many predicted.
In contrast, data centre providers that secured address blocks in the 2010s now hold assets worth significantly more than their acquisition cost. This provides both operational capacity for customer deployments and balance-sheet appreciation that strengthens their competitive position. The strategic advantage extends beyond mere cost avoidance — it creates revenue opportunities through IPv4-inclusive service packages.
Industry veterans recognise this pattern: those who treated IPv4 as a long-term asset now enjoy structural advantages that latecomers cannot easily replicate.
Strategic implications
Treat IPv4 as a capital asset [Priority: High]
Networks that classify IPv4 acquisitions as capital expenditures recognise the long-term value. Leasing remains viable for short-term needs, but ownership provides balance-sheet strength and operational flexibility.
Action: Include IPv4 holdings in annual asset audits and strategic planning processes.
BTW analysis suggests that operators who adopted this approach in the early 2010s now view their IPv4 holdings as competitive differentiators, not just operational necessities.
Audit before acquiring [Priority: High]
Many organisations hold underutilised address space. A comprehensive audit — identifying unused allocations, oversized assignments, and reclamation opportunities — can defer external acquisitions.
Action: Implement RFC 7749 (Address Management Best Practices) before entering the market.
Consider regional dynamics [Priority: Medium]
RIR policies create significant price variations across regions. ARIN addresses typically trade at $55-65, while APNIC addresses range $45-55, and RIPE addresses $50-60. Understanding these dynamics enables cost-effective sourcing, though some RIRs require demonstrated need for transfers, adding complexity to cross-region transactions.
Action: Evaluate multi-region sourcing strategies while accounting for regulatory requirements.
Plan for the IPv6 transition — but don’t bet everything on it [Priority: High]
IPv6 adoption is accelerating, but IPv4 remains essential for compatibility. The optimal strategy combines IPv6 deployment with strategic IPv4 holdings.
Action: Set IPv6 deployment targets while maintaining adequate IPv4 reserves for customer needs.
The question many operators ask BTW is simple: how much IPv4 is enough? The answer depends on your customer base, growth projections, and competitive positioning — but the consensus among industry veterans is clear: err on the side of caution.
The road ahead
IPv4 scarcity is no longer a technical problem — it’s a strategic business consideration. ISPs that treated address space as a long-term asset have gained competitive advantages in cost structure, operational flexibility, and balance-sheet strength.
For networks that missed the IPv4 boom, the path forward involves three phases:
Short-term (0-12 months): Conduct address audit, identify reclamation opportunities, evaluate leasing options for immediate needs.
Medium-term (1-3 years): Develop IPv4 acquisition strategy, implement IPv6 deployment roadmap, establish address management policies.
Long-term (3+ years): Build strategic IPv4 reserves, achieve IPv6 deployment targets, position address space as competitive differentiator.
Here’s what BTW has learned from covering this market for years: the operators who thrive aren’t necessarily the largest or the best-funded. They’re the ones who recognised early that internet infrastructure assets — whether spectrum, fibre, or address space — follow the same economic logic. Scarcity creates value. And value rewards those who plan ahead.
The question isn’t whether to address the gap — it’s whether to lease, acquire, or optimise existing holdings. The answer depends on subscriber growth projections, capital availability, and competitive positioning.
In internet infrastructure, scarcity creates value — and value rewards those who plan ahead.
