With global IPv4 exhaustion continuing in 2025, organizations holding unused address space have a major financial opportunity. IPv4 scarcity has driven market prices higher each year, making IPv4 blocks one of the most valuable digital assets in the tech world. Companies that originally obtained large allocations decades ago can now turn these dormant resources into significant revenue—but only if the sale is done securely and correctly.
Selling IPv4 space requires careful planning, reputation checks, legal documentation, and a fully compliant transfer process. This guide explains exactly how to sell your IPv4 safely while maximizing profits through strategic preparation and trusted broker support.
1. Evaluate Your IPv4 Inventory Before Selling
Before listing your IPv4 space, understand exactly what you have:
- Block size (e.g., /24, /23, /22, /16, etc.)
- RIR region (ARIN, RIPE, APNIC, LACNIC, AFRINIC)
- Whether the block is legacy or reassigned
- Current WHOIS ownership information
- How much of the range is actually in use
- Whether there are any routing announcements
A clear understanding of your inventory helps determine your selling strategy and market value.
2. Clean and Prepare Your IPv4 Block
The cleaner the block, the higher the price. Buyers pay more for IP ranges with no reputation issues.
Before selling, check for:
- Spam blacklists
- Malware or botnet activity
- Abuse history
- Geolocation errors
- Routing inconsistencies
A clean, reputation-safe block increases demand and boosts the sale price. IPv4 Hub’s reputation-checking tools can help you verify and clean your range before listing.
3. Understand Current IPv4 Market Pricing
IPv4 prices vary based on:
- Block size
- Cleanliness
- Region
- Buyer demand
- Transfer urgency
- Market supply levels
In 2025, typical prices range between $40–$60 per IP, with larger or cleaner blocks selling at a premium. ARIN-region IPv4 blocks often command higher prices due to strong global trust.
Working with a broker ensures you list at accurate, competitive pricing instead of underselling valuable resources.
4. Use a Trusted IPv4 Broker to Stay Safe
Selling IPv4 without professional support is risky. Fraud, transfer failures, and payment issues are common when dealing directly with unknown buyers.
A trusted broker provides:
Full seller and buyer verification
Confirming identity, ownership, and legitimacy.
Blacklist and reputation screening
Ensuring your block meets buyer standards.
Secure escrow services
Protecting your payment until the transfer is complete.
Contract and LOA preparation
Making sure all legal documents are accurate and compliant.
RIR transfer management
Handling ARIN, RIPE, APNIC, and inter-RIR requirements.
Faster sales through a verified buyer network
Reducing waiting time and maximizing profit potential.
Brokers like IPv4 Hub remove the risks and complexities associated with private sales.
5. Complete a Fully Compliant IPv4 Transfer
A proper IPv4 transfer requires strict adherence to RIR policies. A successful transfer includes:
- Preparing a valid LOA (Letter of Authorization)
- Verifying ownership via registry records
- Submitting transfer requests to the appropriate RIR
- Buyer justification (required in some regions)
- Updating WHOIS records
- Releasing escrow funds only after approval
Skipping any step can delay or invalidate the entire sale. Using an experienced broker ensures every detail is handled correctly.
6. Sell Unused or Unnecessary Subnets for Extra Value
Many organizations discover that only part of their IPv4 address space is being used. Subnetting allows you to sell:
- /24 blocks from a larger allocation
- Unused portions of legacy Class B or Class C ranges.
- Consolidated segments after network optimization
Selling smaller blocks gives you multiple revenue opportunities and helps you retain only the IPv4 space you actually need.
7. Consider Leasing Instead of Selling for Long-Term Income
If you want to maintain ownership while generating ongoing revenue, leasing is a strategic alternative. Leasing provides:
- Monthly recurring income
- Control of your IPv4 assets
- Long-term yield is higher than one-time sales.
- Low maintenance through broker-managed assignments
IPv4 Hub can help list your block for lease if steady revenue aligns better with your goals.
Selling IPv4 Safely Starts With Preparation and Expertise
Selling IPv4 space is one of the most profitable moves organizations can make in today’s scarcity-driven market. But safe selling requires proper verification, compliance, pricing strategy, and secure payment handling. By cleaning your block, understanding its value, and working with a trusted broker like IPv4 Hub, you can maximize profit while eliminating risk.
