How to Sell IPv4 Addresses
Maximize the value of your unused IPv4 address space. From valuation to transfer completion — your complete guide to selling IPv4.
The IPv4 Selling Opportunity
With IPv4 exhaustion driving demand, unused address space represents significant untapped value.
How to Sell IPv4 Addresses Step by Step
Follow these five steps to sell your IPv4 blocks securely and get the best possible return.
Assess Your IPv4 Holdings
Identify the unused IPv4 address space in your allocation. Check your RIR account for current assignments, review utilization records, and determine which blocks are no longer needed. Even a single /24 block can be monetized.
Get a Valuation
Your block's value depends on several factors: size (larger blocks command higher per-IP prices), RIR region (RIPE blocks are typically most valuable), blacklist/reputation status, and BGP routing history. Contact ipv4.center for a free, no-obligation valuation.
List on a Marketplace
Choose a reputable broker and list your block on their marketplace. You can set your own asking price or accept the current market rate. A good broker will advise you on optimal pricing strategy to balance speed and value.
Buyer Verification & Agreement
Once a buyer is found, the broker handles KYC (Know Your Customer) checks on both parties. A purchase agreement is drafted covering price, transfer timeline, and conditions. Buyer funds are deposited into escrow for your protection.
RIR Transfer & Payment
The broker manages the entire RIR transfer process, coordinating with both parties and the registry. Once the transfer is approved and reflected in the RIR database, escrow releases the funds to you. The entire process is handled professionally and securely.
What Affects IPv4 Value
Understanding these factors will help you set the right price and maximize your return.
Block Size
Larger blocks command premium per-IP pricing. A /16 (65,536 IPs) is worth significantly more per-IP than a /24 (256 IPs).
RIR Region
RIPE NCC blocks typically fetch the highest prices due to strong European demand. ARIN and APNIC blocks also command strong values.
Blacklist Status
Clean blocks with no active blacklistings are worth more. Blocks flagged on spam or abuse databases may sell at a discount.
BGP History
Blocks with clean routing history and no involvement in hijacking incidents are more attractive to buyers and command higher prices.
Block Type
Provider Independent (PI) vs Provider Aggregatable (PA) space, and legacy vs allocated blocks can affect transferability and pricing.
Market Timing
IPv4 prices fluctuate with supply and demand. Monitoring market trends can help you time your sale for maximum return.
Key Considerations
- Minimum transferable block is /24 (256 IPs)
- Ensure you have legal authority to sell the block
- Blocks must be clean (no active blacklistings)
- Transfer requires cooperation from both parties' RIR accounts
