With IPv4 addresses becoming harder to find and their prices rising in 2025, companies that own unused IPv4 blocks have valuable digital assets. If you have leftover IPv4 addresses, you can sell them to other networks that need them to grow. This can make you a lot of money and help other networks grow at the same time. This guide will help you figure out how much your IPv4 blocks are worth, how to follow transfer rules, and how to deal with the money and tax issues that come up when you sell your space.
Why selling IPv4 addresses will be profitable in 2025
There is still more demand than supply because there is a global shortage of IPv4. Depending on the region, reputation, and block size, clean IPv4 space now costs between $35 and $50 per IP. This means:
- You can sell a /24 block (256 IPs) for between $9,000 and $13,000.
- A block of /22 (1,024 IPs) can be worth between $38,000 and $50,000.
- Blocks that are bigger, like /16, can be worth hundreds of thousands of dollars.
As values keep going up, a lot of businesses are looking at address holdings that were once thought to be unimportant.

Step 1: Find out how much your IPv4 block is worth.
You need to know how much your block is worth before you list your space. Important things to think about are:
1. Block Size: Bigger blocks (/20, /19, /16) cost less per IP but are worth more overall.
2. IP Reputation: Space that isn’t blacklisted and is clean sells faster and for more money.
3. RIR Region: ARIN and RIPE blocks usually cost more because they are in high demand around the world.
4. Market Trends: Prices change every month, and brokers and marketplaces publish the current averages.
5. Routing History: Buyers are more likely to buy when ranges have been stable for a long time.
Use brokers’ valuation tools or pricing databases to get an idea of what the market value is. A lot of sellers also ask for quotes from more than one marketplace so they can compare offers.
Step 2: Learn about RIR transfer rules
Before you sell, check with your regional Internet registry to see if your block can be transferred:
- ARIN (North America): Needs notarized papers, signed transfer requests, and yearly fees. Both the buyer and the seller go through validation.
- RIPE NCC (Europe/Middle East): The transfer process is simple; the seller must delete any items from the database.
- APNIC (Asia-Pacific): Needs checks on justifications and approvals for transfers.
- LACNIC (Latin America): Transfers are only allowed after strict policy checks and document reviews.
Most regions allow inter-RIR transfers under certain conditions, which lets sellers reach buyers all over the world.
Step 3: Get the Block Ready to Sell
People who want to buy IP space want it to be clean and ready to use. To get the most value:
- Get rid of old DNS or rDNS references
- Make sure there are no reports of abuse going on.
- Make sure the block is routed or not routed, depending on what the buyer wants.
- Get legal papers that show you own the property.
A trustworthy broker or site like IPv4Hub.net can check these things before they are listed.
Step 4: Finish the Transfer
The process usually goes like this after you accept an offer:
- Signing a deal to transfer
- Putting buyer money in escrow
- Sending in the RIR transfer request
- RIR review and approval (1 to 4 weeks, depending on the area)
- Update the WHOIS database for the buyer’s company
When the job is done, escrow gives you the money.
Step 5: Know What Taxes Will Mean
You might think about selling IPv4 blocks:
- If the block is seen as an asset, there are capital gains.
- If sold as part of normal business, it counts as ordinary income.
- Depreciable property based on how you keep your books
To make sure you’re following all the rules in your area, talk to a tax professional who knows about digital asset transactions.
In 2025, unused IPv4 blocks became valuable financial assets. Organizations can safely and profitably make money off of their address space if they know about valuation, transfer policies, and tax issues, and if they use trusted marketplaces like IPv4Hub.net.
