Getting Started


How long does it take to sell addresses?
The sale process can be rapid or require months, depending on the price asked by the seller and the marketplace supply of the block size in question.

How long does it take to transfer addresses after a sale is complete?
IPv4.GLOBAL has transferred blocks as quickly as two days. On average they require approximately three weeks from the completed sale.


Who pays IPv4.GLOBAL’s commission on completed sales?
The seller pays our commission. That commission comes from the total sale price. (See transfer fees below.)

Our commission varies by block size. When sellers register they receive documentation of our fees.

A buyer’s total purchase price is what is listed as a buy now price on the site or is agreed to at auction. Buyer’s total outlay may include transfer fees (see below).

What are the fees charged by the regional registries for transfers?
Each party (both buyer and seller) is responsible for the fees charged by their respective RIR. Each RIR has their own transfer fees:

What is the process for funds transferring from buyer to seller?
Once purchased, our site generates an invoice with all escrow options. Payment options include a free in-house escrow service, a partnership with that comes with a small fee for the buyer, or payment by credit card via Stripe for purchases under $30,000.

How long does it take to transfer money to a seller?
Once funds are confirmed into escrow, via the option chosen by the buyer, our team will reach out to the seller to initiate the transfer. Upon completion and confirmation that the block is registered under the buyer’s account, funds are released less our commission.


What are the restrictions (requirements) on selling addresses?
When selling IPv4 address blocks:

  • In ARIN the block must have been owned for at least one year, or 5 years if it was received from the wait list.
  • In RIPE a block must have been owned for at least 2 years before it can be transferred again. Unless it is Legacy, then there is no hold period.
  • In APNIC if block begins with ‘103’ it must have been owned for 5 years after APNIC allocation to be transferable.
  • In LACNIC a block must have been owned for at least one year before it is transferable.

* For full policies, see RIR Information below.

What are the restrictions (requirements) on buying addresses?
When buying IPv4 address blocks each RIR has its own “justification / utilization” requirements. The buyer must show projections or utilization rates for the desired space over some specific period:

  • In ARIN, a buyer must demonstrate use of at least 80% of current IPv4 holdings, and 50% of the requested space over the next two years.
  • In RIPE: 50% utilization within five years.
  • In APNIC: Utilization of 25% of the requested addresses immediately and 50% within one year.
  • In LACNIC: 80% of current holdings & utilization of 25% of the requested addresses immediately and 50% within one year.

* For full policies, see RIR Information below.

Can I transfer between RIRs?
Yes, all RIRs (except AFRINIC) permit transfers of IPv4 addresses to/from each other

Registered User Information

What information is required for an IPv4.Global registration?
Your name, email, company name, address, and phone number. The purpose is to demonstrate you are a legitimate buyer or seller by confirming your business affiliation. This information is also required to process the transfer.

Why must registrations be approved?
Both active buyers and sellers must be registered to participate to ensure only qualified buyers make offers on address blocks and legitimate owners offer them for sale.

What are the advantages of being a registered user?
All registered buyers have access to specific block information including the entity offering the addresses for sale and the specific CIDR of the block. All users can use the “Notify Me” feature of the site to monitor price movements of specific block sizes.

What are the advantages of being a registered seller?
Registered sellers can offer blocks for sale, track their prior sales, and change pricing of their blocks.

What are the advantages of being a registered buyer?
Buyers, in addition to bidding on and buying blocks, can view their personal transaction history on the site.

How Buying Works

Auctions end on a date set by the seller. Bids are online by registered users only and conclude either with the closing date or the choice of a “buy now” option for the block offered for sale.

Auction Minimum
Every seller specifies a “starting price”, which is the minimum price that is acceptable to that seller.

Buy Now
Typically priced above auction pricing, these are prices at which a block can be purchased immediately, ending the auction.

Private Sales
IPv4.GLOBAL facilitates the transfer of blocks between buyer and seller privately when the parties request this assistance.

IPv4.Global leases blocks /19 and larger.

How Selling Works

Upon submission of a block on our site an Engagement agreement is sent via Adobe Sign for the seller’s signature. Once signed a member of our team will reach out and get your block listed for sale on our website.

Sellers set minimum acceptable prices for auctions and – when selected – buy now prices.
