Summary

  • ARIN’s 7 August Caribbean IPv6 review ranks 31 jurisdictions using the average of available APNIC, Google and Meta IPv6 traffic measurements, with a June 2026 cutoff.
  • ARIN says a source may not report every country or territory, so a jurisdiction’s value can be calculated from a different available-source set than another row’s value.
  • The table can remain a useful comparative indicator while gaining a small source-coverage receipt: inclusion state, observation time, calculation rule, prior-year comparability and correction history for each row.

The striking thing about ARIN’s Caribbean IPv6 review is not a number near the top of the table. It is a sentence in the method note. The 31 results are based on the average of available IPv6 traffic measurements published by APNIC, Google and Meta. Each source uses its own approach. Each may be absent for a country or territory. Each jurisdictional figure therefore reflects the average of the sources available for that place.

That is a sensible disclosure, and it deserves to be read literally. The page is not claiming to have observed every network in the Caribbean. It calls the ranking a comparative indicator of measured IPv6-capable traffic, not a comprehensive assessment of every operator, institution or network. It also refuses the most tempting shortcut in year-on-year interpretation: a decline alone does not reveal its cause. Network deployment, configurations, traffic patterns and measurement-source availability or coverage can all matter.

Those limits make the ranking more useful, not less. A reader can see that Saint Barthélemy is first in this particular comparative measure at 68.62%, that Suriname rose to third at 53.05%, and that Guadeloupe’s published gain was 22.83 percentage points. The figures describe the review’s measured surface. They do not settle whether one territory has the best architecture, whether a provider completed a migration, or whether a government policy worked.

But a second question remains unanswered by the public table. What exactly is the evidence composition of a particular row? ARIN says the result is an average of whichever of three sources were available, yet it does not publish the source-inclusion set for each jurisdiction. A reader cannot tell from the page whether two rows rest on the same three-source mix, whether one has fewer contributing observations, whether the source mix changed from the prior year, or how the published figure was rounded after the inputs were assembled.

That is not evidence that the table is wrong. It is a reason to separate a score from the account of how the score was formed. A jurisdiction that rises by twenty points may have a real operational change behind it. It may also have a changed measurement composition. The page establishes neither explanation for any named territory. When the available-source set is invisible, the prudent conclusion is not to choose between them in public prose.

ARIN already shows another useful boundary in the table. Some jurisdictions are marked as being in the LACNIC region. That label is not a defect, a transfer of authority or a claim that one registry owns the outcome. It is a reminder that a Caribbean comparison can cross registry-service boundaries while number-resource administration remains regional. Geography is one column of interpretation; institutional jurisdiction is another.

The missing object is therefore a source-coverage receipt, not a new central dashboard or a demand for raw traffic. For every listed jurisdiction, ARIN could publish the review-cycle identifier, geographic and RIR label, named sources included or unavailable, observation and retrieval time, number of included sources, calculation and rounding method, and whether the prior-year comparison used an equivalent source composition. A correction line could show whether later data revised a row or left it intact.

The receipt must keep its limits. It should not expose addresses, subscribers, customer traffic, source credentials, per-operator data or unpublished source internals. It should not convert three independent measurement systems into a single regional truth authority. And it should not label a source’s absence a failure. Its purpose is simply to make the average inspectable at the same level at which the average is being compared.
