IPv4 Allocation and Renumbering Policies
At InterLIR, we know every ISP’s journey with IPv4 addresses comes with its own set of rules and nuances. According to the policy NRPM 4.2.2, if you're an ISP organization without a direct hand from ARIN in the form of assignments or allocations, you’re eligible for a fresh batch of IPv4 addresses, starting from a tidy /22 block. This serves as the baseline, keeping ARIN's minimum allocation sizes in mind.
On the other hand, for those ISPs that don’t have any direct allocations, assignments, re-allocations, or reassignments, InterLIR makes it simple: you automatically get qualified for a /24 block. No hoops to jump through verifying how efficiently you've used your previous IPv4 space because, well, you didn’t have any! But if you’ve got big plans that need more than a /24, all you need to do is prove how you’ll actually use those extra IPs by submitting documentation that aligns with NRPM 4.2.4.3. It’s like showing your work in math class-only this time it pays off.
For ISPs already handling re-allocations or reassignments, InterLIR expects you to keep your IPv4 farm in good order. It means demonstrating that you’re squeezing every bit of value from the addresses you hold. The criteria are laid out in NRPM sections 4.2.3 and 4.2.4, making sure addresses don’t just sit idly by when they could be fueling customers’ connectivity dreams.
When you come knocking with your initial request, be ready to impress with some solid paperwork. Here’s what InterLIR typically asks to see:
- A detailed list of CIDR prefixes or ranges assigned to dynamic pools, complete with the service type such as DSL or wireless, plus the city or region they cover, how busy they get at peak times (peak utilization percentage), and how many customers are enjoying service from each pool.
- A list of static IP addresses or subnets assigned to customers, paired with the names of those lucky customers for each IP or subnet - transparency matters.
- IP addresses dedicated to web hosting, along with at least one domain name per IP so you show InterLIR that those addresses are doing their job serving websites.
- Finally, a list of IP addresses or subnets allocated to your internal equipment and infrastructure, together with hostnames or device names, because even the backbone gear deserves recognition.
Making Additional Allocation Requests
Stepping beyond the initial allocation? InterLIR expects that you’ve got your documentation in order and can explain precisely why your current needs call for more IPv4 addresses. It’s not about grabbing more than you need - it’s about proving that each IP will be put to good, efficient use, which keeps the whole system fair and balanced for everyone.

Why Buying IPv4 Addresses Now Makes Smart Sense
Snap Up IPv4 Addresses Before Prices Hit the Stratosphere
IPv4 addresses are becoming about as rare as a sunny day in winter. As their availability shrinks, prices climb steadily. Waiting too long means you’ll pay more or risk missing out entirely. Buying IPv4 addresses today is like planting a money tree-spend less now and watch your investment grow in value over time.
Lock Down Your IPv4 Addresses with InterLIR Today
Securing IPv4 addresses early isn’t just smart, it’s necessary. InterLIR makes it straightforward to claim your piece of the diminishing IPv4 pie. By acting now, you save money and avoid the scramble that comes with scarcity. It’s a classic case of 'the early bird gets the best IPs.'
Own Your IPs Fully with InterLIR-No Strings Attached
Buying IPv4 addresses through InterLIR hands you full ownership and control. No more hunting around for temporary solutions or risky leases. Once you have your IPs, they’re yours to use, manage, and profit from without the headache of recurring sourcing efforts. Think of it as investing in a solid foundation instead of renting shaky scaffolding.
Enjoy Reliable and Secure IPv4 Connections
With InterLIR, you’re not just buying IP addresses-you’re investing in your business’s peace of mind. You avoid the pitfalls of IPs with a sketchy past or that might vanish without warning. Stable IP ownership means smoother operations, better reputation, and zero surprises on the connectivity front.
Standard IPv4 Block Requirements and Documentation
When you're ready to grab an IPv4 block, one size does not fit all. At InterLIR, the minimum chunk you can snag is a /24 block. It’s the sweet spot that balances usability and scarcity. Just like picking the right pair of shoes, you need the right size to keep your network comfortably running.
All blocks are managed following the trusted NRPM 4.3.6.1 guidelines. This policy ensures the pristine order and fair use of IPv4 space across all users. At InterLIR, we stick to these standards so you get reliable, compliant transactions every time.
What We Need From You: Usage Proofs
Proving that you actually need that IPv4 block is non-negotiable. InterLIR requires you to demonstrate that at least half of each previous allocation is put to good use. This isn’t just bureaucratic red tape - it’s about making sure IPs go to those who use them effectively.
Better yet, an overall efficiency rate of 80% across all your IP holdings shows you’re not just hoarding addresses. And there’s a promise you need to keep: your requested block should ramp up to at least 50% utilization within two years. Think of it as showing your IP space isn’t just a dusty attic, but a buzzing workspace.
Gather Your Paper Trail: What Documentation Matters
Additional IPv4 requests at InterLIR come with a homework assignment. You'll need to lay out a detailed subnet mapping for every previous block you own. This map isn't just a boring list - it’s a story of how each subnet plays a part in your network. We want the purpose of every subnet spelled out and the number of IPs actively used, to build trust in your network's efficiency.
On top of that, you’ll provide a forward-looking subnet plan for the new block you’re chasing. Describe each subnet’s purpose, how many IPs you expect to use in the first 12 months, and projections for the next 24 months. This forecast demonstrates you’re not just dreaming big but planning responsibly.
It’s important not to forget the details: each subnet’s purpose, current and planned utilization numbers - these help InterLIR connect the dots and say, “Yep, this applicant plays by the rules and needs these IPs.”
