IPv4 Brokerage or RIR Waiting List: Making the Right Call
IPv4 brokerage services and Regional Internet Registry (RIR) waiting lists are two very different roads to the address space your network needs. The free pool ran dry back in 2011 at IANA, and since then all five RIRs have followed suit. So organizations scaling up their infrastructure face an uncomfortable choice: get in line and hope, or buy on the open market. Pick wrong and you might delay a product launch, watch infrastructure costs balloon, or find yourself stuck halfway through a migration.
Here we’ll look at both options in detail — timelines, costs, transfer requirements, risks — so IT managers, network engineers and ISP operators can line up their acquisition strategy with the business roadmap instead of guessing.

The IPv4 Exhaustion Context
Each RIR hit the wall at its own pace. ARIN exhausted its free pool in 2015, RIPE NCC in 2019. APNIC and LACNIC ran out earlier, and AFRINIC in 2017. Since then, RIRs have kept waiting lists for returned or reclaimed blocks — a supply that’s unpredictable and, in most regions, tiny compared to demand.
Prices, meanwhile, keep climbing. A single /24 has traded at roughly $50–$60 per address in recent years, which puts a /24 block at about $15,000–$20,000 on the open market. The trend has been upward as cloud providers, CDNs and enterprises fight over a fixed supply. Many analysts now see IPv4 as something odd: an asset that has historically held or gained value rather than depreciating.
How RIR Waiting Lists Work
When organizations hand back address blocks — usually after bankruptcy, mergers, or reclamation efforts — the RIR doesn’t sell them. They go on a waiting list. What does that mean in practice?
- Unpredictable timelines: Waits range from months to several years. RIPE NCC’s list alone has exceeded thousands of requests, and APNIC and ARIN face similar backlogs relative to what actually gets returned.
- No cost guarantee: The allocation itself carries no market price, sure. But you still pay membership and administrative fees — and the real expense is the opportunity cost while you sit and wait.
- Limited block sizes: Returned blocks rarely match what you actually need. You might get a /24 when your network requires a /22.
- No size flexibility: Requests must come from organizations with documented, justified needs under RIR policies (RIPE’s minimum allocation rules for LIRs, for example).
How IPv4 Brokerage Works
An IPv4 broker handles the transfer of address blocks between a verified seller and a buyer: escrow, RIR paperwork, due diligence, blacklist screening. The whole thing. The process usually goes like this:
- Requirement definition: You specify block size (a /22, /23 or /24, say), RIR region, and routing requirements.
- Sourcing and due diligence: The broker verifies clean IP reputation, checks the RIR registry history, and confirms the seller actually has the legal right to transfer.
- Escrow and payment: Funds sit in escrow until the transfer is approved. Nobody gets paid early.
- RIR transfer approval: Transfers under ARIN, RIPE, APNIC and LACNIC policies typically close in 2–8 weeks, depending on the registry.
- Delivery: The block lands in your RIR account, ready to announce via BGP.
Reputable marketplaces such as IP4 Market offer verified sellers, transparent pricing and escrow-protected transactions — which removes the counterparty risk you’d take on buying privately through forums or other unvetted channels. (And yes, that risk is real.)
Head-to-Head Comparison
| Factor | RIR Waiting List | IPv4 Brokerage |
|---|---|---|
| Timeline | Months to multiple years, unpredictable | Typically 2–8 weeks end-to-end |
| Cost | No market price, but admin fees + opportunity cost | ~$40–$60 per IP depending on block size and region |
| Block size control | Limited; you take what’s returned | Choose exact size and region |
| Certainty | No guaranteed delivery date | Contractually defined transaction |
| Due diligence burden | Handled by RIR (clean allocations) | Broker-managed: blacklist checks, registry history, escrow |
| Investment recovery | None — allocation is not an asset | Purchased blocks can be leased out or resold later |
Matching Strategy to Your IT Roadmap
Choose the waiting list if…
- Your need is exploratory or far-future, with no fixed deadline.
- Budget is extremely tight and you can absorb the delay risk.
- You already have enough space and just want a future top-up at no acquisition cost.
Choose IPv4 brokerage if…
- A launch date, contract or compliance requirement is tied to address space availability.
- You need a specific block size or RIR region for routing, geolocation or peering reasons.
- You see IPv4 as an investment — plenty of organizations buy blocks now, use them, and lease the surplus to offset costs.
- You’d rather avoid the legal and reputational exposure of unverified private sales.
Practical Tips for a Safe IPv4 Purchase
- Verify blacklist status: Check blocks against Spamhaus, Barracuda and BGP-related reputation databases before committing to anything.
- Confirm registry history: Make sure the block has a clean allocation chain and no legacy disputes hanging over it.
- Use escrow: Never wire funds directly to an unknown seller. Escrow protects both parties until the RIR approves the transfer.
- Plan routing lead time: After the transfer you’ll need to update your RIR objects, create route/RPSL objects and announce via BGP — budget 1–2 weeks for global propagation and geolocation feed updates.
- Consider leasing: If capex is tight, leasing IPv4 space through a marketplace can bridge short-term needs. Ownership still tends to win long-term at current price trends, though.
Frequently Asked Questions
How long does an IPv4 transfer take? With proper documentation, ARIN and RIPE transfers typically complete in 2–8 weeks. APNIC and LACNIC timelines vary but run in the same ballpark.
Is buying IPv4 addresses legal? Yes. All five RIRs maintain formal transfer policies that allow the sale and transfer of address blocks between verified organizations.
Will IPv4 prices keep rising? Historical data shows consistent appreciation since exhaustion, driven by fixed supply and sustained demand from cloud and enterprise buyers. Most analysts expect continued upward pressure, though short-term fluctuations do happen.
Can I buy now and sell later? Yes — owned IPv4 blocks are transferable assets. Plenty of organizations treat them as operational infrastructure and a store of value at the same time.
Conclusion: Certainty Wins for Serious Roadmaps
RIR waiting lists cost nothing upfront — and everything in uncertainty. For any IT roadmap with real deadlines, IPv4 brokerage delivers the speed, block-size control and legal protection that a list simply can’t offer. When you’re ready to buy, work with a trusted marketplace. IP4 Market provides verified sellers, escrow-secured transactions and competitive per-IP pricing, which makes it a dependable partner for securing your network’s address space.
