IPv4 Address Sellers

An overview of our marketplace and services

Our platform aids the transfer of IPv4 addresses blocks and AS Numbers via private transactions and through our online marketplace.

The marketplace lets users sell IPv4 address space directly, providing an efficient sales process for transactions.

The Basics

Selling addresses is straightforward.

  • Register
    Request a registration for auction access. This is quick and simple.
  • List Addresses
    Set list specifications, “buy now” and minimum auction prices.
  • Escrow Funds
    Buyer remits funds via IPv4.GLOBAL’s free escrow services.
  • Transfer
    We help transfer the IP addresses within the relevant RIR(s).
  • Confirm
    IPv4.GLOBAL confirms the transfer and disburses funds.

The Details

Not complicated but important.

  • Winning
    The successful seller is notified at the close of the auction.
  • Buy Now
    Some sellers establish a “buy now” price in advance.
  • Payments
    Payments are due five business days from the end of the auction. Wire or ACH payments are required.
  • Fees
    Buyers are responsible for the payment of all RIR transfer fees.
  • Financing
    IPv4.GLOBAL provides financing for qualified sellers who require it.


Registration is an easy, no-obligation process. Both active buyers and sellers must be registered to participate to insure only qualified users engage with offerings in the marketplace. In addition to buying and selling opportunities, registered users have access to detailed information on each block offered that is not available to the general public.

The Not-So-Fine Print

Transfer Timelines

Once a sale has been made, the timeframe to completed transfer depends on the speed with which buyer and seller respond to the relevant RIR’s requests for information and documentation. This normally ranges from two weeks to one month.

In order to speed up the transfer process, we encourage – and many buyers comply – approval prior to bidding.

Inter-RIR Transfers

We assist with this every day. Generally, a transfer between RIRs takes one week longer than one that happens within a single RIR.
