The global shortage of IPv4 addresses has created an active and profitable secondary market for organizations that hold unused IP ranges. Whether your company acquired IP space years ago, consolidated infrastructure, migrated to cloud systems, or transitioned partially to IPv6, your unused IPv4 addresses may now be worth tens of thousands of dollars. Selling them in 2025 is not only financially rewarding but also helps meet the ongoing demand from businesses, hosting providers, SaaS platforms, and data centers around the world.
If you have unused IPv4 blocks, this guide explains how to sell them safely, maximize profit, avoid risks, and complete a fully compliant transfer.
Why IPv4 Addresses Are Valuable Assets in 2025
Even with IPv6 adoption improving, the global internet still heavily depends on IPv4. New technologies, legacy networks, and expanding online platforms all require reliable IPv4 space. Because Regional Internet Registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC) have run out of new IPv4 allocations, the only available supply comes from organizations willing to sell.
This scarcity has created strong market value. Clean IPv4 ranges now sell at premium rates, often between $40–$60 per IP, with prices rising annually. For organizations holding unused blocks, this represents a major opportunity to convert dormant digital resources into significant profit.
1. Evaluate the IPv4 Range You Want to Sell
Before selling, you need to know what you have. Determine:
- The block size (e.g., /24, /23, /22)
- Whether the block is legacy or assigned
- Which RIR is the block registered under
- How many addresses are free and usable
- Whether the range is currently routed or assigned
A broker can help you identify your IP assets if you are unsure.
2. Clean and Prepare Your IPv4 Addresses
Buyers prefer clean, reputation-safe IPs. Before selling, make sure the block is free from:
- Spam blacklists
- Malware history
- Abuse complaints
- Incorrect routing entries
- Geolocation errors
Using tools like IPv4 Hub’s blacklist checker helps you verify and clean your range. Clean blocks sell faster and at higher prices.
3. Understand Pricing and Market Demand
IPv4 prices fluctuate based on:
- Region (ARIN blocks often cost more)
- Block size
- Reputation and cleanliness
- Current market supply
- Transfer urgency
- Buyer industry (VPN, hosting, cloud, etc.)
Larger blocks like /22 or /21 often command premium pricing because they are increasingly difficult to find. Smaller blocks like /24 sell quickly due to high demand from hosting providers.
Working with a broker helps ensure you receive the best possible price.
4. Work With a Trusted IPv4 Broker for Safe Selling
Selling IPv4 addresses without guidance can be risky. A reputable broker protects you at every step:
- Verifies buyer legitimacy
- Handles negotiations
- Manages blacklist checks
- Ensures clean and compliant transfer
- Oversees secure escrow payment
- Handles LOAs, contracts, and documentation
This prevents fraud, pricing mistakes, and failed transfers.
5. Complete the RIR-Compliant Transfer Process
To sell IPv4 legitimately, the transfer must be processed through your RIR. The typical steps include:
- Signing a sales agreement
- Providing a Letter of Authorization (LOA)
- RIR verification of ownership
- Submission of transfer request
- Buyer justification (if required)
- Updating WHOIS and registry records
- Release of escrow funds after completion
A broker ensures this process is smooth and error-free.
6. Benefits of Selling Your Unused IPv4 Addresses
Selling unused IP space gives organizations:
Immediate financial gain
Convert dormant assets into revenue.
No ongoing maintenance or responsibility
Unused IPs require tracking, routing checks, and registry updates. Selling eliminates overhead.
Better resource allocation
Focus on IPv6, cloud migration, or modern infrastructure instead of holding unused IPv4 blocks.
Opportunity to reinvest
Use the revenue for upgrades, expansion, or development.
7. Consider Leasing If You Want Recurring Income
If you do not want to give up long-term ownership, leasing your IPv4 range may be an alternative. Leasing provides:
- Monthly recurring revenue
- Control over your IP assets.
- Higher long-term value than a single sale
- Flexibility to reclaim IPs in the future
Many organizations choose to lease instead of selling to generate steady profit.
