As the scarcity of IPv4 addresses continues to grow in 2025, businesses that own unused IPv4 blocks now find themselves sitting on valuable digital assets. With the global shortage of IPv4 addresses driving up prices, selling your unused IPv4 blocks can be a profitable venture. Whether you’re a large enterprise or a smaller company with excess IP space, monetizing your unused IPv4 addresses can provide a significant return and help other organizations expand their network infrastructure.
This guide will help you understand how to determine the value of your IPv4 blocks, follow the required transfer rules, and navigate the financial and tax considerations involved in selling your IPv4 addresses. By leveraging trusted brokers like IPv4Hub.net, you can complete sales transactions safely, efficiently, and profitably.
Why Selling IPv4 Addresses Will Be Profitable in 2025
The demand for IPv4 addresses continues to outpace supply, and prices remain high. As of 2025, clean IPv4 space can cost between $35 and $50 per IP, depending on factors such as region, reputation, and block size. This makes selling your unused IPv4 blocks an attractive option for generating revenue.
- A /24 block (256 IPs) can be worth between $9,000 and $13,000.
- A /22 block (1,024 IPs) can range from $38,000 to $50,000.
- Larger blocks like /16 can fetch hundreds of thousands of dollars.
As the value of IPv4 addresses continues to rise, businesses are realizing that even smaller blocks of IP space, once considered insignificant, can now provide a financial windfall.

Step 1: Find Out How Much Your IPv4 Block Is Worth
Before you list your unused IPv4 block, it’s crucial to understand its market value. Several factors influence the price of IPv4 space:
1. Block Size: Larger blocks like /16 and /20 are typically worth more overall but cost less per IP. Smaller blocks like /24 or /23 may command a higher price per IP but are worth less overall.
2. IP Reputation: Clean IP space (not blacklisted or flagged for abuse) is highly valued. Buyers are more willing to pay premium prices for clean, routable IPv4 blocks.
3. RIR Region: Blocks located in high-demand regions like ARIN and RIPE generally cost more than those in other areas due to the higher demand for IP addresses in these regions.
4. Market Trends: IPv4 prices fluctuate monthly based on demand and supply. Regularly checking broker valuation tools and pricing databases can help you understand current market trends and get the best value for your block.
5. Routing History: Blocks that have a stable routing history and have been in use for a long time are more attractive to buyers. If the block has been stable and without issues, it can command a higher price.
Step 2: Learn About RIR Transfer Rules
Each Regional Internet Registry (RIR) has its own set of transfer policies for IPv4 addresses. Familiarizing yourself with these rules is essential before attempting to sell your IPv4 block.
ARIN (North America):
- Transfer Requirements: Notarized papers and signed transfer requests are necessary, along with annual maintenance fees.
- Validation Process: Both the buyer and the seller undergo a validation process to ensure compliance.
RIPE NCC (Europe/Middle East):
- Transfer Requirements: Relatively simple transfer process; however, the seller must ensure that any historical records are cleared from the registry.
APNIC (Asia-Pacific):
- Transfer Requirements: Transfers require justification and approval based on the buyer’s needs.
LACNIC (Latin America):
- Transfer Requirements: Transfers are subject to strict policy checks and document reviews.
It’s essential to understand the transfer policies of the relevant RIR region in order to avoid delays or compliance issues.
Step 3: Get Your IPv4 Block Ready to Sell
To maximize the value of your IPv4 block, it must be clean and ready for use by the buyer. Before listing your IP space, follow these steps to prepare the block for sale:
- Clear DNS and rDNS References: Ensure there are no outdated DNS or reverse DNS (rDNS) references associated with the block.
- Check for Abuse: Ensure there are no reports of abuse, such as spamming or hacking, associated with the IP block.
- Routing Status: Confirm whether the block is routed or not, depending on what the buyer is looking for.
- Legal Ownership: Have all legal documents that prove you own the IP space ready for verification.
A reliable broker or platform like IPv4Hub.net will help verify these elements before listing your IPv4 block.
Step 4: Complete the Transfer
Once you accept an offer, the transfer process typically involves the following steps:
- Signing a Transfer Agreement: Both the buyer and seller sign a legal transfer agreement to initiate the process.
- Escrow: The buyer’s payment is placed in escrow until the transfer is completed.
- Submit Transfer Request: Both parties submit a transfer request to the appropriate RIR.
- RIR Review: The RIR reviews the request, ensuring compliance with all policies. This can take 1 to 4 weeks depending on the region.
- WHOIS Update: Once approved, the RIR updates the WHOIS database to reflect the new owner of the IPv4 block.
- Payment Released: Once the transfer is complete, the payment held in escrow is released to the seller.
Step 5: Understand the Tax Implications
Selling IPv4 addresses may have tax implications. There are a few important points to consider:
- Capital Gains: If the IPv4 block is considered an asset, any profit from the sale may be subject to capital gains tax.
- Ordinary Income: If the IPv4 block is sold as part of regular business operations, it may be considered ordinary income and taxed accordingly.
- Depreciable Property: Depending on how the block is recorded in your financial statements, it may be treated as depreciable property.
To ensure you’re complying with local tax regulations, it’s recommended to consult a tax professional familiar with digital asset transactions.
