Complete Guide to ARIN IPv4 Transfers
Everything you need to know about buying, selling, and transferring IPv4 address blocks through the American Registry for Internet Numbers (ARIN). This guide covers the complete process from pre-approval to WHOIS update.
What is an ARIN IPv4 Transfer?
An ARIN IPv4 transfer is the process of moving IPv4 address block ownership from one organization to another within the American Registry for Internet Numbers (ARIN) region, which covers the United States, Canada, and parts of the Caribbean.
Since ARIN exhausted its free pool of IPv4 addresses in September 2015, the only way to obtain new IPv4 address space in the ARIN region is through the secondary transfer market. ARIN's Section 8.3 (Transfers to Specified Recipients) and Section 8.4 (Inter-RIR Transfers) policies govern these transactions.
As an ARIN-registered facilitator listed on the Specified Transfer Listing Service (STLS), IPv4 Depot has deep expertise in navigating ARIN's transfer policies. We've facilitated thousands of successful transfers, helping organizations acquire the IPv4 space they need efficiently and securely.

Important Note
ARIN requires that recipients demonstrate a justified need for IPv4 addresses. Working with an experienced facilitator like IPv4 Depot significantly improves approval rates and reduces processing time.
Step-by-Step ARIN Transfer Process
Determine Your Need
Assess how many IPv4 addresses your organization requires. ARIN requires that you demonstrate a justified need for the addresses you wish to acquire. This includes documenting your current utilization rates and projected growth over the next 24 months.
ARIN typically requires 80% utilization of existing space before approving additional allocations.
Submit Pre-Approval Request
Before any transfer can take place, the recipient must obtain pre-approval from ARIN. Submit a request through ARIN's Online portal demonstrating your organization's justified need. This involves providing network diagrams, utilization data, and growth projections.
Pre-approval can take 2-4 weeks. IPv4 Depot can assist with the application to expedite the process.
Find a Seller & Negotiate
Once pre-approved, you need to locate a seller with available IPv4 address blocks. IPv4 Depot maintains an extensive inventory of verified, clean IP blocks across multiple sizes. We handle price negotiation, ensuring you get competitive market rates.
Working with a registered facilitator like IPv4 Depot ensures you're getting clean, non-blacklisted blocks.
Execute the Transfer Agreement
Both buyer and seller sign a transfer agreement outlining the IP range, pricing, escrow terms, and transfer timeline. Funds are placed in escrow for protection. IPv4 Depot prepares all documentation and coordinates between both parties.
Always use escrow protection. IPv4 Depot includes this as standard in every transaction.
Submit Transfer Tickets to ARIN
Both the buyer and seller must submit transfer tickets to ARIN through their respective ARIN Online accounts. ARIN reviews the transfer request, verifies the pre-approval, and confirms both parties' authorization.
Both parties must have active ARIN Online accounts with Organization IDs (Org IDs).
ARIN Review & Approval
ARIN's Registration Services team reviews the transfer request. They verify that the recipient has been pre-approved, the source has authority over the addresses, and all documentation is in order. This review typically takes 5-10 business days.
Respond promptly to any ARIN inquiries to avoid delays. IPv4 Depot monitors the process and handles all communications.
WHOIS Update & Completion
Once ARIN approves the transfer, WHOIS records are updated to reflect the new registrant. The IP block is now officially registered to the buyer. Escrow funds are released to the seller, completing the transaction.
After WHOIS update, allow 24-48 hours for global DNS propagation before routing the new addresses.
