What Are IPv4 and IPv6?
IP addresses are unique identifiers that allow devices to communicate over the internet or private networks. They’re essential for routing traffic, enabling secure communication, and supporting modern IT environments.
IPv4
- 32-bit addressing
- ~4.3 billion total addresses (mostly allocated)
- Common format:
192.0.2.1 - Still widely used but limited in capacity
IPv6
- 128-bit addressing
- Virtually unlimited addresses (~340 undecillion)
- Common format:
2001:0db8:85a3::8a2e:0370:7334 - Designed for scalability, automation, and security
Why the Transition Matters
IPv4 and IPv6 are not directly compatible. That’s why most organizations operate in dual-stack mode—running both protocols during the transition.
With IPv4 exhaustion in full effect and IPv6 adoption accelerating, your business needs to plan around both. That includes acquiring legacy IPv4 blocks, enabling IPv6-ready infrastructure, and maintaining security and compliance across both.
Why Choose IPv6 and IPv4 Address Solutions?
Core Problems IP Solutions Solve
- IPv4 Address Exhaustion – Acquire hard-to-find IPv4 blocks for growth or resale
- Future Incompatibility – Ensure your network supports IPv6-native apps, devices, and partners
- Operational Fragmentation – Centralize IP tracking, routing, and management
- Security Risks – Reduce exposure from unmanaged or unmonitored address space
- Compliance & Traceability – Maintain clear records for audits, legal holds, and geolocation rules
Who Should Consider IP Address Services?
- ISPs, data centers, cloud providers managing large-scale IP pools
- Enterprises migrating to hybrid cloud or multi-region infrastructure
- Organizations scaling networks in APAC, LATAM, or IPv6-preferred regions
- Any business facing IPv4 shortages or needing structured IP lifecycle management
If your growth depends on connectivity—you depend on a smart IP strategy.

Implementation Insights
Transitioning to IPv6—or expanding IPv4 allocations—requires more than just numbers. Here’s what we recommend:
- Conduct an IP Inventory
Understand what’s currently assigned, available, routed, and in use. - Define Growth Requirements
Project how many addresses you’ll need over 1–3 years, across locations and use cases. - Segment by Business Unit or Region
Prevent overlap, reduce misrouting, and simplify provisioning. - Review Network Hardware
Ensure routers, firewalls, and appliances support IPv6 without disruption. - Enable Dual-Stack Where Needed
Avoid IPv6-only gaps—especially if partners still rely on IPv4. - Integrate With DNS and DHCP
Centralize name resolution and dynamic assignment to reduce manual effort.

IPv6 vs. IPv4: What's the Difference?
Common Challenges and Misconceptions
“We already have enough IPs.”
Maybe for now. But new services, devices, and growth can make even a /24 feel small fast.
“IPv6 isn’t needed yet.”
That depends on your customer base and regions. In parts of Asia, Europe, and mobile networks, IPv6 is already the default.
“It’s too complex to manage.”
Not with the right tools and advisory support. We simplify IP lifecycle management from acquisition to routing.
“You can’t get IPv4 anymore.”
Not true. The market is tight—but address blocks can still be acquired or leased with the right brokerage.
How to Choose the Right IP Address Partner
We advise evaluating:
- Block availability and legitimacy
- RIR registration and governance knowledge
- Security checks and reputation audits
- Support for transfer, leasing, and reverse DNS
- Expertise in dual-stack and IPv6 planning
ITBroker.com helps you align your IP strategy with real-world demand—whether you're growing, consolidating, or modernizing.
IPv4/IPv6 Address Pricing Models
Pricing can vary based on:
- Block Size – /24s are more common; /22 or /20s are higher cost and harder to find
- Acquisition vs. Leasing – Leasing lowers capex but may limit control
- Reputation Quality – Clean blocks (no abuse history) carry premium value
- Registry Costs – ARIN, RIPE, and APNIC fees may apply to transfers
- Market Timing – Demand surges can drive temporary spikes in price
We provide real-time price benchmarks to help you buy smart and scale safely.

FAQs About IPv6 and IPv4
Q: Can I still get IPv4 addresses today?
Yes—through transfers, brokers, and secondary markets.
Q: Do I need both IPv4 and IPv6?
Most organizations run both in parallel (dual stack) during transition periods.
Q: Are IPv6 addresses more secure?
IPv6 includes native security features, but proper configuration still matters.
Q: How long does IP acquisition take?
Leasing can be immediate. Transfers may take days to weeks depending on registry approval.
