LACNIC IPv4 transfers became one of the most important IPv4 market signals in 2025. Outbound inter-RIR volume from the region increased from about 142,000 IPv4 addresses in 2024 to about 7.94 million addresses in 2025.
The key change was not simply more transactions. It was the appearance of large IPv4 blocks that could influence supply, buyer expectations, pricing behavior, and global IPv4 sourcing strategies.
The global IPv4 market has operated under scarcity conditions for many years. Regional Internet Registries have little or no freely available IPv4 space left, while demand remains strong across cloud infrastructure, hosting, data centers, ISPs, CDNs, corporate networks, VPN platforms, and other services that still depend on IPv4.
As a result, the secondary IPv4 market has become more important. Companies now lease, buy, sell, and transfer IPv4 address blocks through structured transactions between existing holders.
Traditionally, most attention has focused on the ARIN, RIPE NCC, and APNIC regions. These markets have been more familiar to buyers and brokers, with higher transaction volumes and more predictable transfer experience.
LACNIC, by contrast, has often been viewed as a less active and more complex region. The address space existed, but the market appeared less transparent and the transfer process less predictable.
Quick answer: LACNIC is becoming more relevant in the global IPv4 market because NRO inter-RIR transfer data through Q1 2026 confirms a major 2025 increase in outbound IPv4 volume from the region. LACNIC is not necessarily the busiest market by number of transfers, but it is emerging as an important source of large-scale IPv4 liquidity.
LACNIC outbound inter-RIR transfer count grew moderately, but address volume increased more than 50-fold.
A few large blocks can affect market liquidity more than many small /24 or /23 transfers.
A major part of LACNIC’s 2025 outbound volume moved toward the ARIN region.
LACNIC-origin IPv4 blocks require careful checks of registry status, documentation, routing, RPKI, and reputation.

According to NRO inter-RIR transfer statistics, cumulative outbound IPv4 transfers from LACNIC stood at about 142,000 IPv4 addresses across 64 transfers by the end of 2024. By the end of 2025, this had increased to approximately 7.94 million IPv4 addresses across 93 transfers.
The latest available NRO report for Q1 2026 shows the same LACNIC outbound inter-RIR totals, which means the key market shift still belongs to 2025, while 2026 currently confirms rather than extends that trend.
At the same time, the number of outbound inter-regional transfers increased only from 64 to 93. This distinction is important: the change was not driven by a sudden wave of small transfers, but by the emergence of large address volumes.
In the IPv4 market, the number of transactions does not always show real liquidity. Dozens of small /24 or /23 transfers can create operational activity, but they may not materially change the supply balance.
Large blocks are different. A /16 contains 65,536 IPv4 addresses. A group of blocks comparable to a /15, /14, or larger can influence buyer expectations, seller behavior, negotiation strategy, and market pricing.
Key market insight: LACNIC does not need to become the busiest RIR by transfer count to become important. Its strategic value may come from large IPv4 blocks that were previously less visible to the global market.
The 2025 shift does not mean the entire LACNIC region is suddenly selling off IPv4 resources. A more accurate interpretation is that some large holders have become more active or more willing to bring address space to the global market.
Several factors help explain why LACNIC IPv4 transfers are now receiving more attention.
Many organizations received IPv4 addresses years ago, when they were primarily treated as technical infrastructure rather than high-value assets. Some of these resources may now be underused, inefficiently distributed, or no longer aligned with the holder’s business model.
As prices for large blocks corrected from earlier highs, some holders gained an incentive to monetize IPv4 resources instead of waiting indefinitely.
IPv4 demand exists inside Latin America and the Caribbean, but local buyers may not always be ready to absorb very large blocks quickly. The global market is broader.
A buyer from the ARIN, RIPE NCC, or APNIC region may have a larger budget, a more urgent infrastructure need, or a stronger ability to use a large address volume. For the holder of a large block, an inter-RIR transfer can therefore be more attractive than a long search for a local buyer.
LACNIC transfers were often perceived as complex because inter-regional transfers require coordination between two RIRs, verification of the seller, confirmation of the buyer’s readiness, complete legal documentation, and synchronized registry updates.
Today, professional IPv4 market participants have more experience with this process. It is becoming clearer which documents must be prepared, where delays usually occur, and how the seller, buyer, broker, and registries should coordinate each step.
LACNIC allows inbound and outbound inter-regional IPv4 transfers without requiring a merger or acquisition between the companies involved. This gives holders a formal policy path to bring IPv4 address space to external buyers.
The policy path does not make every transaction simple, but it creates a procedural foundation. Once the market learns how to use that foundation, larger transactions become easier to structure and close.
Brazil deserves particular attention because it represents the largest share of delegated IPv4 space in the LACNIC region. Mexico is also a major regional holder.
Operationally, Brazil and Mexico require additional attention because organizations in those countries work through their corresponding National Internet Registries for resource procedures. For large IPv4 transfers, this means the documentation path, timing, and communication flow may differ from a standard direct LACNIC case.
For buyers and brokers, LACNIC-origin IPv4 sourcing should not be treated as a simple listing exercise. The exact country, current resource holder, registry relationship, corporate documents, and transfer path can materially affect the closing timeline.
A LACNIC IPv4 transfer becomes more manageable when it is treated as a structured process rather than a sequence of unexpected obstacles.
Confirm the legal resource holder, registry status, authority of signatories, and right to transfer the IPv4 block.
Check the receiving RIR’s requirements, buyer eligibility, corporate documents, and justification requirements where applicable.
Review WHOIS/RDAP records, ownership history, routing, RPKI/ROA status, IRR objects, abuse reputation, and blocklist history.
Collect corporate documents, authorization documents, transfer agreements, invoices, and any registry-specific forms before launch.
Synchronize the seller, buyer, broker, LACNIC or NIR contact, and the receiving RIR to avoid idle time between steps.
Update registry data, route objects, RPKI, abuse contacts, geofeed information, and operational documentation after completion.
For buyers, LACNIC creates an additional source of supply. This may be especially valuable for companies looking for large IPv4 blocks and willing to work through an inter-regional procedure.
However, a LACNIC-origin block should never be evaluated only by prefix size and price. The asset must be reviewed from legal, registry, routing, and operational perspectives.
For sellers, the current market creates a window of opportunity. IPv4 addresses that were previously treated as technical resources can now be managed as liquid digital infrastructure assets.
The selling strategy matters. A large block can be sold as a whole, or it can be split into smaller ranges. Each option has different commercial and operational consequences.
The best option depends on urgency, block quality, price expectations, registry status, buyer demand, and the seller’s willingness to participate in a more complex process.
For brokers, LACNIC is becoming a region where buyer access alone is not enough. The transaction requires procedural knowledge, country-specific awareness, and careful preparation.
A professional IPv4 broker adds value by reducing the risk that a transfer will fail, stall, or become commercially unattractive before closing.
Missing or inconsistent corporate documents can delay the registry review.
The seller, buyer, LACNIC or NIR, and receiving RIR must move in the correct sequence.
Routing history, blocklists, and abuse records can affect buyer confidence and final pricing.
Several extra months of uncertainty can affect price, payment terms, and buyer commitment.
The trend should not be overstated. The sharp growth in 2025 may have been connected to a limited number of large transactions rather than a broad sell-off across the region.
Still, the market has received an important signal: large volumes from LACNIC are possible, and they can be handled through formal inter-RIR transfer procedures.
The future depends on whether more holders in Brazil, Mexico, Argentina, Chile, Colombia, and other LACNIC-region countries begin to view IPv4 as a marketable asset. If they do, LACNIC may take a more important place in the global IPv4 supply structure.
If the 2025 jump proves partly temporary, the perception of the region has still changed. LACNIC is no longer just a peripheral participant in the IPv4 transfer market.
For buyers, sellers, and IPv4 holders, InterLIR focuses not only on matching supply and demand, but also on the operational checks that make a transaction safer: registry status, documentation, routing readiness, reputation, RPKI, and transfer requirements.
As LACNIC becomes more relevant for large-scale IPv4 liquidity, careful preparation becomes essential. The value is not only in finding a block, but in helping the transaction close cleanly.
LACNIC IPv4 transfers are transactions in which IPv4 address blocks registered in the LACNIC region are transferred between eligible organizations. They may be intra-regional transfers within LACNIC or inter-RIR transfers involving another Regional Internet Registry.
LACNIC is important because NRO inter-RIR transfer data through Q1 2026 confirms a major 2025 increase in outbound IPv4 volume from the region. This shows that LACNIC can be a source of large-scale IPv4 liquidity, especially for buyers seeking large IPv4 blocks.
No. The key point is not that LACNIC became the largest market by number of transfers. The important change is that the region demonstrated large-block liquidity, with millions of IPv4 addresses moving through inter-RIR transfers in 2025.
The growth appears to reflect the activity of large holders, stronger global demand, price correction in large blocks, and improving practical experience with LACNIC inter-RIR transfer procedures.
They can be complex, especially when large blocks, national registry procedures, inter-RIR requirements, or historical ownership issues are involved. However, the process becomes more predictable when documentation, registry status, buyer readiness, and technical due diligence are prepared in advance.
Buyers should check the legal holder, registry status, WHOIS/RDAP records, ownership history, transfer eligibility, routing history, RPKI/ROA status, IRR objects, abuse reputation, blocklists, and receiving RIR requirements.
The IPv4 market is becoming more global, and sources of supply are becoming more diverse. In this new structure, LACNIC can occupy an important niche: not necessarily as the most active region by transfer count, but as one of the most interesting regions for large-scale IPv4 liquidity.
For buyers, LACNIC offers another direction for sourcing large IPv4 blocks. For sellers, it creates an opportunity to monetize unused or underused resources. For brokers, it creates a market where careful process management can deliver meaningful value.
Against the backdrop of price correction, cautious buyers, and growing supply of large blocks, LACNIC is no longer a region to ignore. In 2025, it demonstrated that it can bring millions of IPv4 addresses to the global market.
