Quick Overview
Complete IPv4 transfer facilitation with legal compliance, due diligence, and RIR coordination across all major registries.
What is IPv4 Address Transfer?
IPv4 address transfer is the regulated process of transferring ownership and registration of IPv4 address blocks between organizations. Since RIPE NCC exhausted its IPv4 pool in November 2019, the secondary transfer market has become the primary method for organizations to acquire additional IPv4 address space.
Transfers are governed by Regional Internet Registries (RIRs) including RIPE NCC, ARIN, and APNIC. Each RIR maintains specific policies to ensure transfers serve legitimate networking needs while preventing address hoarding or speculation. All transfers require proper documentation, justification, and compliance with both sending and receiving RIR policies.
Professional transfer facilitation significantly reduces timeline and ensures compliance. Typical transfer duration: 2-4 weeks with proper preparation.
Types of IPv4 Transfers
Understanding different transfer mechanisms and their specific requirements
Intra-RIR Transfer
Transfer between parties within the same RIR region (e.g., both organizations in RIPE region).
Simplest process. Faster approval. Single RIR approval required. Typical timeline: 2-3 weeks.
Inter-RIR Transfer
Transfer between parties in different RIR regions (e.g., RIPE to ARIN or ARIN to APNIC).
Complex process requiring dual RIR coordination. Both sending and receiving RIR approval needed. Typical timeline: 3-4 weeks.
Merger/Acquisition Transfer
IPv4 address transfer as part of corporate merger, acquisition, or asset purchase agreement.
Requires corporate documentation proving business relationship. May qualify for expedited RIR processing.
IPv4 Transfer Process
Six-step process from market analysis to completed transfer
Market Analysis & Matching
We analyze current IPv4 market pricing, identify suitable blocks matching your requirements, and connect buyers with sellers. Market intelligence ensures fair pricing and clean reputation blocks.
Comprehensive Due Diligence
We verify IP reputation across major blocklists, review allocation history, check legal status, validate routing configuration, and ensure RPKI compliance. Critical for avoiding problematic address space.
Price Negotiation & Agreement
We negotiate market-rate pricing (typically €30-45/IP), establish payment terms, draft transfer agreements, and coordinate escrow if required. All terms documented clearly.
RIR Documentation Preparation
We prepare all RIR-required documentation including justification letters, corporate verification, resource needs assessment, and compliance declarations. Proper documentation critical for approval.
RIR Transfer Submission & Approval
We submit transfer requests to relevant RIR(s), respond to clarification requests, coordinate between parties, and track approval status. Professional handling reduces delays.
Transfer Completion & Activation
Upon RIR approval, WHOIS records are updated, registration transferred to new holder, RPKI ROA configured, and reverse DNS delegated. We provide post-transfer technical support.
Total timeline: 2-4 weeks from signed agreement to completed transfer. Intra-RIR transfers faster (2-3 weeks), inter-RIR transfers 3-4 weeks.
RIPE Transfer Policies & Compliance
Regulatory framework governing IPv4 transfers in RIPE region
RIPE NCC enforces strict policies for IPv4 address transfers under policy document ripe-733. Compliance with these policies is mandatory for transfer approval.
Mandatory Transfer Requirements
- Both transferring and receiving parties must be RIPE NCC members (LIR or End User organization)
- Minimum transfer size: /24 (256 addresses) - smaller blocks cannot be transferred independently
- Recipient must provide documented justification demonstrating legitimate need for IPv4 resources
- 24-month holding period: transferred addresses cannot be re-transferred for 24 months post-approval
- Aggregation requirement: received addresses must be aggregated with existing holdings where technically feasible
Transfer Restrictions & Limitations
- No speculative transfers: addresses must be allocated for active network infrastructure, not investment
- No artificial fragmentation: allocations cannot be split solely to circumvent minimum transfer size
- RIPE transfer fee: €50 per transfer transaction (paid to RIPE NCC)
- Inter-RIR transfers must comply with both sending and receiving RIR policies simultaneously
- Legacy space transfers (pre-RIR allocations) require special approval and additional documentation

Critical Due Diligence Checks
Essential verification before purchasing IPv4 address blocks
IP Reputation Analysis
We verify addresses against 50+ spam blocklists (Spamhaus, SORBS, Barracuda), check abuse history databases, validate email deliverability scoring, and review historical usage patterns. Clean reputation is essential for email servers and public services.
Allocation & Ownership History
We review complete WHOIS history, trace previous allocations and assignments, verify chain of custody through RIR records, and ensure no disputes or ownership conflicts exist. Historical analysis reveals potential issues.
Legal Status Verification
We confirm seller has legal authority to transfer, verify addresses are free of liens or encumbrances, validate all RIR fees are current, review corporate standing, and ensure compliance with jurisdictional requirements.
Routing & RPKI Validation
We check current global routing status, verify BGP announcement history, validate RPKI ROA configuration, analyze route object records, and ensure proper registration in IRR databases for seamless routing post-transfer.

Common IPv4 Transfer Scenarios
Real-world use cases requiring professional transfer services
Acquiring IPv4 for Growth
Organizations needing additional IPv4 address space for infrastructure expansion, customer base growth, new service launches, or multi-region deployment.
Example: Hosting provider with /23 (512 IPs) acquiring additional /22 (1,024 IPs) to support 500 new dedicated servers and customer VPS instances. Total investment: €30,000-45,000 at current rates.
Monetizing Surplus IPv4
Organizations with unused or under-utilized IPv4 blocks can monetize surplus address space through regulated transfer market.
Example: Enterprise completed IPv6 migration and has unused /21 (2,048 IPs). Current market value: €60,000-90,000. After 24-month holding period, resources can be transferred to organizations with active need.
M&A IP Asset Consolidation
Corporate mergers, acquisitions, and asset purchases require transferring IP resources between organizations to consolidate network infrastructure under unified management.
Example: Parent company acquiring subsidiary with /20 (4,096 IPs). Transfer consolidates resources under parent's LIR membership, simplifies operations, and enables unified IP address management and RPKI deployment.
