Understanding the IPv4 Address Market
IANA Exhaustion
Global IPv4 pool exhausted in 2011
No new allocations possible from RIRs
Rising Demand
Prices have increased 300%+ since 2015
Driven by cloud, IoT, and 5G growth
4.3B Total Addresses
IPv4 uses 32-bit addressing
Finite supply with growing demand
Mature Market
Regulated secondary market ecosystem
Governed by ARIN, RIPE, APNIC
The IPv4 address market emerged after the Internet Assigned Numbers Authority (IANA) exhausted the global pool of IPv4 addresses in 2011. While IPv6 adoption has been growing, the vast majority of internet infrastructure still relies on IPv4, creating sustained demand for these finite resources.
Regional Internet Registries (RIRs) — including ARIN (North America), RIPE NCC (Europe), and APNIC (Asia-Pacific) — allocated their remaining IPv4 address pools shortly after IANA exhaustion. This created a secondary market where organizations buy, sell, and lease IPv4 address blocks from existing holders.
Today, the IPv4 market is a mature, regulated ecosystem. Prices are influenced by block size, registry region, IP reputation, and market demand. Organizations need IPv4 addresses for expanding network infrastructure, launching new services, cloud deployments, and maintaining operations that haven't yet transitioned to IPv6.
Why IPv4 Addresses Are Scarce
IPv4 uses 32-bit addresses, providing approximately 4.3 billion unique addresses. With billions of devices now connected to the internet, this pool was exhausted in 2011. New allocations are no longer possible from RIRs, making the secondary market the only source for additional IPv4 space.
IPv4 vs IPv6
While IPv6 offers a virtually unlimited address space (128-bit), adoption remains incomplete. Many legacy systems, applications, and networks still require IPv4 connectivity. IPv4 Depot helps organizations bridge this gap with both IPv4 and IPv6 solutions.
IP Block Sizes
IPv4 Transfer Process
Our streamlined 4-step process makes acquiring IPv4 addresses straightforward and secure. Most transfers complete in just 2-3 weeks.
Acquisition Request
Contact IPv4 Depot with the block size you need and your ARIN pre-approval ticket number. We'll help you through the pre-approval process if needed.
Free consultationContract & Agreement
We match you with available inventory and send a sales contract with the agreed-upon IP range, pricing, transfer fees, and escrow details.
Escrow or invoiceOwnership Transfer
Once funds are wired, both parties open transfer tickets with the Regional Internet Registry. Transfers typically complete within 2-3 weeks.
RIR managedTransaction Complete
WHOIS records are updated to reflect you as the registered holder. Funds are released from escrow and the IP block is fully yours.

Encrypted Communications

Fraud Prevention & Verification
Multi-Database Blacklist Screening
Every IP block is checked against major blacklists such as Spamhaus, Barracuda and SpamCop, plus several proxy-detection databases, before any transaction proceeds.
Seller Identity Verification
We verify the identity and authorization of every seller, confirming they have legitimate ownership and authority to transfer the address space.
Pre-Transfer Reputation Review
Before closing, we review each block's blacklist status, abuse history and routing so you know what you're buying before the transfer completes.
RPKI/ROA Verification
We verify and assist with Resource Public Key Infrastructure (RPKI) signing and Route Origin Authorization (ROA) setup to ensure routing security.
Legal Compliance
All transfers comply with the relevant RIR policies (ARIN Section 8.3/8.4, RIPE-713, APNIC transfer policies) and applicable laws and regulations.
Fraud Prevention Protocol
Our multi-step verification process includes document authentication, ownership chain verification, and real-time monitoring to prevent fraudulent transfers.
