Key Facts
Essential information about ARIN IPv4 transfers at a glance.
ARIN Transfer Policies
ARIN governs IPv4 transfers through two primary policies. Understanding which applies to your situation is the first step.
Policy 8.3 — Specified Transfer
- For transfers between specified recipients
- Buyer must demonstrate need for the addresses
- 24-month supply justification required
- Most common for buying IPv4 from ARIN
Policy 8.4 — Inter-RIR Transfer
- For transfers between ARIN and other RIRs
- Both RIRs must approve the transfer
- Takes longer (4–8 weeks typically)
- Useful when buyer/seller are in different regions
ARIN Transfer Process
Follow these six steps to complete an ARIN IPv4 transfer successfully.
Verify ARIN Org IDs
Both the buyer and seller need active ARIN Organization Identifiers (Org IDs). If you don't have one, you can create it through the ARIN Online portal. This is a prerequisite for any ARIN transfer.
Needs Justification
The buyer prepares a 24-month IP utilization plan demonstrating justified need for the addresses. This includes current usage, growth projections, and technical justification for the requested block size.
Due Diligence
Comprehensive verification of the IP block including blacklist checks across 300+ databases, WHOIS record verification, ownership confirmation, and BGP routing history review.
Submit Transfer Ticket
Both parties submit the transfer request via the ARIN Online portal. The seller initiates the transfer ticket, and the buyer confirms acceptance. All required documentation is attached.
ARIN Review
ARIN reviews the needs justification and supporting documentation. They may approve the transfer directly or request additional information or changes to the utilization plan.
Transfer Completion
Once approved, the IPv4 resources are moved to the buyer's Org ID. WHOIS records are updated, and the buyer can configure ROA/RPKI records and begin announcing the block via BGP.
Required Documents
Prepare these documents before initiating an ARIN transfer to avoid delays.
- Active ARIN Org ID for both buyer and seller
- Company registration documents
- Government-issued ID of authorized representatives
- Network utilization plan (24-month projection)
- Signed transfer agreement
- Officer authorization letter
