Transferring IPv4 addresses between Regional Internet Registries (RIRs) is a necessary part of global network expansion. As companies grow across continents, the ability to move IP blocks, whether for mergers, infrastructure optimization, or regional requirements, has become essential. However, each RIR has its own policies, documentation rules, and approval processes. Understanding these differences is key to ensuring a smooth and compliant transfer.
Understanding the Role of RIRs in IPv4 Transfers
The world is divided into five RIR regions, but the four most important for commercial IPv4 transfers are ARIN (North America), RIPE NCC (Europe), APNIC (Asia-Pacific), and LACNIC (Latin America).
Each RIR manages IP allocations, maintains ownership records, and enforces transfer rules.
Transferring IPv4 between RIRs requires:
- Verified ownership
- Clean IP reputation (no blacklists)
- Proper justification (varies by RIR)
- Matching transfer policies on both sides
Because IPv4 scarcity is global, cross-RIR transfers have become a routine but regulated activity.
Key Transfer Requirements for Each RIR
1. ARIN Transfer Policies
ARIN is the strictest registry, requiring:
- Officer-signed documents
- Justification of need (for the recipient)
- Clean IP history
- Legal company validation
ARIN allows both intra-RIR and inter-RIR transfers under NRPM 8.4.
2. RIPE NCC Transfer Policies
RIPE does not require justification for the receiving party, making transfers faster.
Requirements include:
- Verified legal ownership
- 24-month holding period (cannot transfer newly received blocks for 2 years)
- Agreement from both parties
3. APNIC Transfer Policies
APNIC requires:
- Documented need for the receiving party.
- Valid membership
- Section 8 policy compliance
- No unresolved disputes or policy violations
APNIC allows inter-RIR transfers to ARIN and back.
4. LACNIC Transfer Policies
LACNIC’s requirements include:
- Need justification
- Full legal verification
- The originating block must not be from legacy space.
- No recent policy violations
LACNIC is growing in transfers as Latin American businesses expand globally.
How the Cross-RIR IPv4 Transfer Process Works
Although RIR policies differ, the transfer flow generally follows these steps:
- Verification of Ownership
Confirm the seller is the legitimate holder of the block through WHOIS and RIR database checks. - IP Cleanliness Check
Ensure the block is free of blacklisting, routing issues, or geolocation conflicts. - Buyer Qualification
Some RIRs require justification (ARIN, APNIC, LACNIC). Others do not (RIPE). - Dual RIR Ticketing
Both RIRs open transfer tickets simultaneously to validate documents and execute the transfer. - Payment & Escrow Protection
Funds remain locked until both RIRs approve the transfer. - Completion & WHOIS Update
Once approved, the block is reflected in the receiving RIR’s database.

Tips for a Smooth IPv4 Transfer Between RIRs
Work with a Verified IPv4 Broker
A broker ensures you avoid fraud, policy mistakes, or compliance delays.
Prepare Documentation Early
Especially for ARIN and APNIC transfers, where justification is required.
Check IP Reputation
Blacklisted ranges can lead to delays or rejection.
Use Escrow for Financial Safety
This protects both buyer and seller during the approval process.
Stay Updated With RIR Policy Changes
Regulations are updated frequently, especially around transfer justification.
Transferring IPv4 addresses across ARIN, RIPE, APNIC, and LACNIC is completely possible, but it requires careful preparation, proper documentation, and compliance with each region’s unique rules. By partnering with an experienced broker like IPv4Hub.net, businesses can ensure fast, secure, and error-free transfers that support global network growth.
