IPv4 addresses are now some of the most sought-after digital goods in the world. The lack of IPv4 space is getting worse even in 2025 because the internet is growing around the world and IPv6 is taking a long time to catch on. As a result, people, businesses, hosting providers, and data center operators can now buy and sell IPv4 addresses as a real investment. New investors need to know how the market works to avoid risks and get the most out of their investments.
This complete guide shows you how to buy and sell IPv4 addresses safely, profitably, and in full compliance with the rules of the global registry.
Why IPv4 Addresses Will Be Worth a Lot of Money in 2025
The market is strong because there aren’t enough IPv4 addresses. The only way to get new IPv4 addresses is to transfer them between organizations. This makes a stable place where clean, reputation-safe IPv4 blocks keep their value.
Key reasons IPv4 is still profitable:
- Limited supply: All major registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC) have exhausted their IPv4 pools.
- High demand: Cloud providers, enterprises, ISPs, and SaaS companies still rely heavily on IPv4.
- Growing leasing market: Investors can earn recurring revenue by leasing IPv4 instead of selling immediately.
- Asset appreciation: IPv4 prices have increased over the past decade and remain strong.
For new investors, this combination makes IPv4 an attractive digital asset.
Part 1: How to Buy IPv4 Addresses as a New Investor
Buying IPv4 requires caution and expert guidance. Unlike traditional investments, IP addresses must be transferred legally through a Regional Internet Registry (RIR).
Step 1: Work With a Trusted IPv4 Broker
A verified broker protects investors by:
- Providing clean, vetted IPv4 ranges
- Conducting blacklist and abuse checks
- Confirming seller ownership
- Handling secure payments through escrow
- Managing all RIR documentation and transfers
For new investors, this eliminates risk and ensures compliance.
Step 2: Choose the Right Block Size
Investors typically purchase IPv4 in blocks such as:
- /24 (256 IPs) – Most popular and easiest to resell or lease
- /23 (512 IPs) – Good for portfolio growth
- /22 (1,024 IPs) – Ideal for hosting or long-term leasing
Smaller blocks offer flexibility, while larger blocks provide better long-term yield.
Step 3: Check Clean Reputation and Blacklist Status
A clean IP block is essential for value. Before buying:
- Check global spam blacklists
- Review routing history
- Verify geolocation accuracy
- Inspect abuse records
IPv4 Hub’s blacklist checker tool is commonly used to validate blocks before purchase.
Step 4: Complete a Secure, Escrow-Protected Transfer
Once the block is verified, investors proceed with:
- Contracts and LOA (Letter of Authorization)
- Escrow payment
- RIR transfer request
- Registry verification and updates
- Final confirmation of ownership
After approval, the investor becomes the official holder of the IP range.
Part 2: How to Sell IPv4 Addresses Profitably
Selling IPv4 addresses is straightforward when using the right process.
Step 1: Prepare Your IPv4 Block for Sale
Before listing your block:
- Remove any harmful routing configurations
- Clean reputation issues
- Update registry information
- Ensure no active abuse or open tickets
Brokers help sellers eliminate issues that could lower the value of the block.
Step 2: Understand Pricing Trends
IPv4 prices vary depending on:
- Block size
- Region (ARIN/RIPE/APNIC markets differ)
- Clean reputation
- Buyer demand
- Transfer speed
In 2025, U.S. IPv4 often commands a premium due to high trust and market stability.
Step 3: Work With a Broker to Find Buyers
A trusted IPv4 broker:
- Markets your block to verified buyers
- Handles negotiations
- Ensures safe payment processing
- Manages the RIR transfer
- Provides legal and compliance support
This prevents scams and maximizes sale price.
Step 4: Complete the RIR Transfer
During the sale:
- Buyer funds are placed in escrow
- Seller signs required transfer documents
- RIR updates the WHOIS
- Funds are released after completion
The process is secure and transparent for both parties.
Part 3: Should You Lease Instead of Sell?
Many investors choose to lease their IPv4 blocks instead of selling.
Advantages of leasing:
- Recurring monthly income
- Control over long-term ownership
- Higher lifetime value than selling
- Growing global demand from hosting and VPN providers
For investors targeting long-term yield, leasing is a powerful strategy.
IPv4 Is a Good Digital Asset for New Investors
In 2025, buying and selling IPv4 addresses could be a good way to make money. IPv4 is still one of the safest digital investments you can make because demand is rising, prices are stable, and supply is limited around the world. New investors can feel good about entering the market and building a strong IPv4 portfolio if they work with a reputable broker, check their reputation, and follow the right transfer procedures.
Understanding the market and getting expert advice will help you make safe and profitable transactions, whether you want to buy, sell, or lease IPv4 space.
