Frequently Asked Questions
Everything you need to know about buying, selling, and leasing IPv4 addresses
IPv4 addresses are the unique numerical identifiers assigned to every device on the internet. With the global pool exhausted since 2011, they have become a scarce and valuable resource. Organizations that need additional IPv4 space must acquire them from existing holders through the secondary market.

We then prepare and send you the purchase agreement, which you must sign and return within 3 business days. After payment via SWIFT, Stripe, Wise, or Crypto, our team handles the RIR transfer. The entire process typically takes 2-4 weeks.
Register an account, add your organization details, and create a sale listing with your IPv4 block information and asking price. Once approved, your listing goes live on the marketplace. When a buyer is found, we handle contracts, escrow, and the RIR transfer process.
