Summary

  • IANA’s page updated on 3 September 2026, using LACNIC data dated 1 September, reports 613 available ASNs, a monthly average of 68 and two-month need of 136. It marks LACNIC as not currently eligible for more.
  • The forecast falls from 0.23% in June 2027 to −6.41% in July. That is a projected run-down, not negative live inventory or evidence of global ASN exhaustion.
  • Replenishment has alternative eligibility tests and requires a request. IANA records LACNIC’s previous request as received on 17 November 2025 and implemented on 19 November; the mechanism has worked, but it is not automatic.

A line that carries on without a delivery

By July 2027, the numbers in IANA’s forecast table for LACNIC have gone negative. An inventory cannot do that in quite the same way as a spreadsheet. It can stop supplying requests, or it can be replenished. The chart is useful because it makes continuing consumption visible. It becomes misleading if its downward extension is mistaken for a prediction that replenishment will never happen.

The LACNIC ASN allocations page describes its purpose more modestly: it uses the current average allocation rate to help estimate eligibility for additional Autonomous System Numbers. These identifiers distinguish autonomous systems. The page is about a regional registry’s stock of them, not the remaining lifetime of the global numbering system.

The September snapshot reports 613 available numbers and 60% available. Its forecast reaches 0.23% in June 2027, −6.41% in July and −19.69% in September. There is no upward replenishment step in that displayed sequence. Reading it as continued run-down at the current rate fits both the sequence and the page’s stated planning purpose. Reading it as a dated shortage announcement does not.

That distinction matters before any alarm is raised. A forecast can expose the need for future action without predicting that the action will fail.

What changed at the input end

The page’s six monthly allocation counts are 81 for March, 69 for April, 47 for May, 69 for June, 67 for July and 74 for August. They sum to 407. Dividing by six gives about 67.83, consistent with the displayed monthly average of 68. The two-month requirement is shown as 136.

This is a check on the published arithmetic, not an audit of the software producing the chart. Nor does agreement make the future certain. A rolling average changes as a new month arrives and an old one drops out. Faster demand can make yesterday’s comfortable buffer less comfortable; slower demand can move the other way. The projection’s far end is conditional on inputs that will not stand still.

For now, the page explicitly says LACNIC is not eligible for an additional allocation. The reported free stock exceeds the displayed two-month need. The news in this snapshot is therefore not an observed supply failure. It is a useful opportunity to distinguish the forecast from the response it is intended to inform.

The response starts before zero

The global allocation policy supplies two alternative routes to more inventory: distribute 80% of the previously received block, or hold fewer free ASNs than two months of need, calculated from the preceding six-month average. The denominators differ. One examines the last block; the other examines current free stock.

IANA allocates in blocks of 1,024, supplying enough for twelve months of registration needs at that historical rate unless the RIR requests fewer. Eligibility and quantity are thus separate decisions. Neither requires waiting for the plotted balance to reach zero.

They also do not cause numbers to arrive by themselves. Under IANA’s request procedure, the RIR submits a spreadsheet and supporting assignment or usage summaries appropriate to its eligibility route and request. A qualifying stock position is an input to an application, not a completed allocation.

LACNIC has already used the mechanism

The previous refill is visible in more than a rule book. IANA’s ASN registry records 274845–275868 under LACNIC, dated 19 November 2025. Counting both endpoints gives exactly 1,024 numbers, matching the latest allocation shown on the current chart page.

The November 2025 performance report adds an actual sequence. IANA received LACNIC’s request on 17 November and acknowledged it that day. Clarification arrived on 19 November, followed by implementation later the same day. The report rates implementation as timely and accurate.

This is positive evidence of replenishment through the existing procedure. It is not a promise that every future request will take the same time. In particular, the report’s 0.1-business-day implementation metric is not the elapsed duration from the original request. Treating it that way would erase the earlier receipt and clarification stages.

The evidence also sets a sensible stopping point. It does not establish that all 613 currently available numbers belong to the last block, or identify which test a future application will use. The global registry still contains unallocated ranges; a regional stock projection is not global exhaustion. And upstream availability alone says nothing decisive about an individual operator’s approval, fees or deployment.

The refill is therefore neither a guarantee to be assumed nor an absence to be invented. It is a real procedure with a documented previous completion. A useful reading of the forecast keeps it in view.
