IPv4 Price History: The Economics of Scarcity 2015–2025

IPv4 price history is, honestly, one of the strangest stories in modern tech economics: a resource that was once handed out for free has appreciated roughly tenfold in a decade. Today /24 blocks are liquid assets that trade for tens of thousands of dollars each.

Why IPv4 Scarcity Created a Multi-Billion Dollar Market

The IPv4 protocol provides approximately 4.3 billion unique addresses. When RFC 791 was published in 1981, that number seemed inexhaustible. It wasn’t. By the early 2010s the five Regional Internet Registries (RIRs) had exhausted their free pools — IANA allocated its final blocks in 2011, APNIC and RIPE NCC entered exhaustion phases shortly after, and by 2015 even ARIN’s available pool had effectively run dry. Only AFRINIC still held meaningful inventory, and that too diminished through the 2010s.

So what happened? Organizations that needed more address space had nowhere to go except the secondary market. And demand kept growing: IoT deployments, cloud expansion, mobile networks, CGNAT workarounds — all of it consumes IPv4. IPv6 adoption, meanwhile, has moved too slowly to relieve the pressure. The result is a market where a single /24 (256 addresses) regularly trades at $30–$50 per address, which puts the aggregate IPv4 address space at an estimated $100–150 billion on paper.

• Fixed supply: No new IPv4 space can ever be created.
• Renewable demand: Every new ISP, SaaS provider, and enterprise network needs addresses.
• Transferable property: RIR policies since 2009 formally recognized address transfers, enabling a legitimate marketplace.

IPv4 Price History: A Decade of Growth (2015–2025)

Track IPv4 prices over the past decade and you see a remarkably consistent upward line, interrupted only by brief corrections. In 2015, /24 blocks traded around $5–$8 per address as ARIN’s waitlist grew. By 2018 prices had climbed to $10–$15 — AWS and Azure were scaling up, and ARIN’s waiting list had stretched to years. Then came acceleration: from 2019 to 2021 prices went from roughly $18 to $25+ per address, driven partly by pandemic-era cloud demand and by major cloud providers quietly acquiring space. From 2022 onward, things settled into the $30–$50 range, with larger blocks (/16 and above) commanding premiums for their operational flexibility.

1. 2015–2016: $5–$8 per address; markets still maturing after early transfer policies.
2. 2017–2019: $10–$18; ARIN and RIPE waiting lists pushed buyers to the secondary market.
3. 2020–2022: $20–$40; pandemic demand and speculative accumulation tightened supply.
4. 2023–2025: $35–$50; prices plateau at elevated levels with steady appreciation.

For buyers planning an acquisition, this history suggests waiting rarely pays. Lease options can work as a hedge for organizations with shorter-term needs. Platforms like IP4 Market publish current pricing benchmarks and connect buyers with verified sellers, which makes it easier to execute purchases at fair market rates rather than by guesswork.

Key Drivers Behind Rising IPv4 Prices

What’s actually behind the decade-long appreciation? Several structural forces:

• RIR restriction policies: Strict transfer requirements, justifications, and regional lockouts limit liquidity and raise transaction costs.
• Institutional buyers: Cloud hyperscalers, CDNs, and private equity firms acquire large portfolios, pulling blocks out of circulation.
• IPv6 transition delays: Even by 2024, fewer than half of Google’s users were connecting over IPv6. IPv4 remains operationally essential.
• Leasing market growth: Yield-seeking holders now lease unused space at $0.10–$0.30 per address monthly — supporting underlying asset values much the way rental income supports real estate.
• Security and reputation premiums: Clean blocks with no blacklist history or hijacking records command 10–20% premiums, which rewards diligent due diligence.

Put these drivers together and the picture is clear enough: IPv4 has become a scarce, appreciating asset class. Network operators would do well to treat it as both infrastructure and investment.

IPv4 Pricing Today: Market Rates and Regional Differences

¿Cuánto cuesta una dirección IPv4 en 2025? La horquilla habitual va de $30 a $50 por dirección en bloques limpios y enrutables. Los /22 de ARIN o RIPE se pagan con prima: las reglas de transferencia y la demanda de los compradores los han convertido en el tamaño más codiciado. Los bloques grandes, un /16 por ejemplo, suelen situarse en la parte alta del rango, mientras que los más pequeños o con historial dudoso se negocian con descuento. Si prefieres no comprar, el alquiler ronda los $0.30 a $0.60 por dirección y mes. Barrera de entrada mucho más baja.

La región importa, y no poco. El mercado de RIPE sigue muy activo en Europa y Oriente Medio; en Norteamérica manda el volumen de transferencias de ARIN. Las direcciones de APNIC, históricamente más baratas, se han apreciado a medida que el agotamiento regional se hacía más profundo. Y hay un factor que muchos compradores pasan por alto hasta que es tarde: la reputación. Un /24 con historial de spam o actividad de botnet puede negociarse un 10-20% por debajo del mercado hasta que alguien limpie su reputación. Diez minutos de verificación previa ahorran meses de dolores de cabeza.

Should You Buy, Lease, or Sell? Strategic Insights for Network Operators

No hay una respuesta única. Depende de tu horizonte de crecimiento, de tu capital y de lo que necesite tu operación día a día.

• Compra si necesitas espacio de direcciones permanente: infraestructura, estabilidad de enrutamiento o requisitos regulatorios. Con los ritmos de apreciación actuales, comprar suele salir mejor que alquilar a partir del tercer o quinto año.
• Alquila si tu demanda es estacional, por proyectos, o simplemente incierta. Conservas capital y te libras del trabajo de due diligence que exige la propiedad, con flexibilidad para crecer o encoger según convenga.
• Vende o monetiza si tienes asignaciones heredadas sin usar. El espacio parado no rinde nada; venderlo o alquilarlo convierte un activo dormido en capital líquido.

Conclusion: Navigating the IPv4 Market in the Years Ahead

Una década de historia de precios — de 2015 a 2025 — deja una lectura clara: escasez sostenida, demanda creciente y un mercado secundario que ha madurado hasta convertir las direcciones IPv4 en una clase de activo con todas las letras. IPv6 avanza, sí, pero despacio. La mayoría de previsiones apuntan a que la demanda de IPv4 — empujada por el IoT, la expansión de la nube y los límites del CGNAT — mantendrá los precios firmes, cuando no al alza, durante lo que queda de década.

Para quien opera redes, el mensaje cabe en una línea: trata IPv4 como infraestructura y como inversión a la vez. Audita lo que tienes, monetiza lo que no usas y adquiere con criterio lo que sabes que necesitarás. Y tanto si compras, alquilas o vendes, hacerlo a través de una plataforma de confianza, con vendedores verificados y precios competitivos — IP4 Market, por ejemplo — es lo que asegura transacciones seguras, conformes y preparadas para donde evolucione el mercado.
