Why IPv4 Addresses Remain Critical
While IPv6 adoption grows, IPv4 addresses remain essential for internet operations in 2025. RIPE NCC exhausted its IPv4 pool in 2019, creating a secondary transfer market.
Universal Compatibility
IPv4 works with all internet infrastructure globally. IPv6 deployment is progressing but not universal.
Legacy Systems
Critical business applications and network equipment require IPv4 addressing.
Dual-Stack Operations
Most networks run both IPv4 and IPv6 simultaneously for maximum reach.
Established Reputation
Aged IPv4 blocks with clean history provide better email deliverability and reduced blocklist risk.
Available IPv4 Block Sizes
RIPE NCC allocated blocks with clean reputation history
| Block Size | Usable IPs | Typical Use Case | Allocation Timeline |

| /20 | 4,096 addresses | Large ISPs, enterprises | 4-6 weeks |
| /19 | 8,192 addresses | Major networks | 4-6 weeks |
All blocks include RPKI ROA setup and full documentation assistance
IPv4 Allocation Process
Transparent process from inquiry to resource activation
Requirements Assessment
We review your company information, network infrastructure, and justification documentation. RIPE policies require demonstrating need for IPv4 resources.
Block Selection
We propose available IPv4 blocks matching your requirements. All blocks are pre-verified for clean reputation (not listed on spam/abuse databases).
RIPE Transfer Process
We initiate the IPv4 transfer through RIPE NCC's official transfer system. Includes all required documentation and compliance verification.
Resource Activation
Upon RIPE approval, resources are transferred to your account. We assist with RPKI ROA configuration and reverse DNS setup.
Typical timeline: 2-4 weeks from signed agreement to resource activation

IPv4 vs IPv6 Considerations
Understanding when you need IPv4, IPv6, or both
IPv4 Allocation
Pros
- ✓Universal compatibility
- ✓Works with all systems
- ✓Established infrastructure
- ✓No client-side changes needed
Cons
- ✗Limited availability
- ✗Higher cost (market pricing)
- ✗Transfer process required
- ✗Exhausted at RIR level
Best for: Email servers, public services, legacy system compatibility
IPv6 Allocation
Pros
- ✓Abundant address space
- ✓Direct RIPE allocation
- ✓Modern protocol features
- ✓Lower cost
Cons
- ✗Not universal compatibility
- ✗Client support varies
- ✗Requires dual-stack
- ✗Email deliverability challenges
Best for: New infrastructure, cloud-native apps, future-proofing
Recommendation: Deploy dual-stack (IPv4 + IPv6) for maximum compatibility and future-proofing. Start with smaller IPv4 block for critical services.
Common Use Cases for IPv4 Allocation
Real-world scenarios where IPv4 addresses are essential
Web Hosting & Cloud Services
Hosting providers need IPv4 for customer websites, email servers, and control panels. Shared hosting requires multiple IPs for SSL certificates.
Typical: /24 to /22 depending on customer base
Email Infrastructure
SMTP servers require IPv4 addresses with clean reputation for deliverability. Aged IPv4 blocks improve inbox placement rates.
Typical: /24 for dedicated email infrastructure
ISP & Telecommunications
Internet service providers need IPv4 for customer CPE, carrier-grade NAT, and public services. Regulatory requirements may mandate IPv4.
Typical: /22 to /19 for regional operations
Enterprise Networks
Large organizations need provider-independent IPv4 for multi-homing, disaster recovery, and avoiding vendor lock-in.
Typical: /24 to /23 for WAN infrastructure
