Inter-RIR Transfer Eligibility by Region
Understanding the specific eligibility requirements for each Regional Internet Registry (RIR) is critical for successful inter-RIR transfers. Each RIR has distinct policies governing who can transfer resources, when they can transfer them, and under what conditions. This guide provides a comprehensive breakdown of eligibility requirements for all four RIRs that participate in inter-RIR transfers.
Overview of Regional Differences
While all participating RIRs share the fundamental principle of needs-based resource distribution, their specific eligibility criteria vary significantly:
Key differences include:
- Hold period requirements before resources can be transferred
- Needs assessment methodology and timeframes
- Documentation and proof requirements
- Regional presence verification methods
- Post-transfer restrictions and limitations
Understanding these differences is essential for planning your transfer strategy and ensuring compliance with both source and destination RIR policies. For a complete overview of the inter-RIR transfer process, see our Inter-RIR Transfer Process Explained guide.
RIPE NCC Eligibility Requirements
The RIPE Network Coordination Centre serves Europe, the Middle East, and parts of Central Asia. RIPE's inter-RIR transfer policy (RIPE-769) is generally considered one of the most straightforward.

Hold period requirements:
- IPv4 allocations: 24 months after the allocation date
- IPv4 transfers: 24 months after the last transfer date
- ASN transfers: 24 months for scarce resources (16-bit ASNs); otherwise per standard policy
Resource eligibility:
- Minimum transfer size: /24 (256 IPv4 addresses)
- Must be publicly routable address space
- Special-use or reserved space cannot be transferred

- European-based operations or customers
RIPE-Specific Policies
No needs assessment for some transfers: When receiving from RIRs without needs-based outbound requirements, RIPE may not require the 50% utilization plan. However, the basic requirement to have an active presence in the region still applies.
Legacy resources: Legacy IPv4 resources can be transferred, but must first be brought under contract with RIPE NCC. Legacy status is maintained within the RIPE region.
Post-transfer obligations:
- Maintain LIR membership or sponsoring relationship
- Keep WHOIS data current
- Comply with ongoing utilization requirements
- Respond to RIPE NCC communications
ARIN Eligibility Requirements
The American Registry for Internet Numbers serves North America (United States, Canada, and parts of the Caribbean). ARIN's inter-RIR policy (NRPM 8.4) includes some of the most stringent requirements.
Eligibility as Source (Transferring Out)
Basic requirements:
- Must be the registered holder in ARIN's database

Pre-transfer restrictions:
- Must not have received a transfer, allocation, or assignment from ARIN in the previous 12 months

Post-transfer restrictions:
- 36-month waitlist restriction: After transferring resources out, the source entity cannot apply for IPv4 address space under ARIN's waitlist (Section 4.1.8) for 36 months
- This restriction is designed to prevent resource recycling through the free pool
Officer attestation:

- Annual maintenance fees based on resource size
- Fee-for-service model applies
Legacy resources: Legacy resources can be transferred but must first be brought under an ARIN RSA. Legacy holders must comply with current ARIN policies for inter-RIR transfers.
APNIC Eligibility Requirements
The Asia Pacific Network Information Centre serves the Asia-Pacific region. APNIC's inter-RIR transfer policy balances accessibility with needs-based allocation principles.

Minimum size:
- /24 for IPv4 transfers (consistent with other RIRs)
- Must maintain CIDR boundary alignment
ASN transfers: APNIC will recognize inter-RIR ASN transfers only when the counterpart RIR has an inter-RIR ASN transfer policy. Currently compatible with RIPE and ARIN for ASN transfers.
LACNIC Eligibility Requirements
The Latin American and Caribbean Internet Addresses Registry serves Latin America and the Caribbean. LACNIC's inter-RIR transfer policy (LAC-2019-1) became operational in 2020 and includes some unique requirements.

Minimum transfer size:
- /24 for IPv4 addresses (consistent with other RIRs)
Policy compatibility: LACNIC can transfer with RIPE, ARIN, and APNIC. No transfers with AFRINIC due to lack of reciprocal policy.
Language requirements:
- Official languages are Spanish and Portuguese
- English documents may require certified translation
- Communication with LACNIC may be in Spanish/Portuguese
AFRINIC Status
The African Network Information Centre serves the African continent but does NOT currently participate in inter-RIR transfers.
Current Situation
No inter-RIR policy:
- AFRINIC does not have an inter-RIR transfer policy in effect
- No resources can be transferred to or from the AFRINIC region
- Only intra-RIR transfers within Africa are permitted
Policy proposals under consideration:
- 2019-IPv4-002: IPv4 Inter-RIR Resource Transfers (Comprehensive Scope)
- 2020-GEN-006: AFRINIC Number Resources Transfer Policy
- 2019-V4-001: IPv4 Inter-RIR Legacy Resource Transfers
Impact on global transfers: All four participating RIRs (RIPE, ARIN, APNIC, LACNIC) prohibit transfers to/from AFRINIC due to the lack of reciprocal policy.
Intra-RIR only: Organizations in Africa can transfer resources within the AFRINIC region per Section 5.7 of the Consolidated Policy Manual, but cannot participate in the global inter-RIR transfer market.

Common Eligibility Issues and Solutions
Issue 1: Insufficient Hold Period
Problem: Attempting to transfer resources before the required hold period has elapsed.
Solution:
- Verify exact allocation/transfer date from RIR records
- Calculate hold period from the correct starting date
- Wait until hold period requirement is met
- Check for any hold period exceptions in RIR policies
Issue 2: Inadequate Regional Presence
Problem: Cannot demonstrate sufficient operational presence in destination RIR region.
Solution:
- Establish physical office or operational facility in region
- Deploy actual network infrastructure (not just plans)
- Obtain local business registration
- Develop customer base or service area in region
- Document all regional presence elements clearly
Issue 3: Weak Needs Justification
Problem: Destination RIR rejects needs assessment as insufficient.
Solution:
- Provide detailed, realistic utilization plans
- Include network diagrams and infrastructure documentation
- Reference specific use cases and customer requirements
- Show current utilization of existing resources if applicable
- Consider requesting smaller resource amounts
- Work with consultants experienced in needs assessments
Issue 4: Documentation Problems
Problem: Required documents are missing, incomplete, or improperly formatted.
Solution:
- Use official RIR templates and checklists
- Ensure company names match exactly across all documents
- Obtain proper authorization levels for signatures
- Get notarization where required (ARIN transfers)
- Translate documents if needed (LACNIC)
- Have documents professionally reviewed before submission
Issue 5: Legacy Resource Complications
Problem: Legacy resources have different or additional requirements.
Solution:
- Bring legacy resources under contract with current RIR first
- Understand that legacy status may be lost in some regions
- Complete additional verification steps required for legacy space
- Budget extra time for legacy resource processing
