Summary

  • At RIPE 93, Florian Holzbauer singled out the Netherlands’ IPv6 policy as a visible signal in his comparison of municipal services across Europe.
  • The Dutch government’s early-2026 report, measured at 31 December 2025, records full web IPv6 adoption on 85% of 1,273 municipal domains and 71% of 690 shared-public-arrangement domains.

The green patch has an internal border

At RIPE 93, Holzbauer called the Dutch result a visible policy effect. He described a “comply or explain” approach and an end-2021 reachability deadline. Forum Standaardisatie’s record separates the two: IPv6 has been on its mandatory “comply or explain” list since 2010; a government-wide commitment set 31 December 2021 for public websites and email domains to be reachable over IPv6 alongside IPv4.

The latest Dutch government scorecard complicates that success story. Its early-2026 report uses measurements taken at 31 December 2025. Full IPv6 adoption for web traffic reached 85% across 1,273 municipal domains. For 690 domains belonging to shared public arrangements, it was 71%: a 14-percentage-point gap. Central-government domains scored 66%.

The report uses the Dutch category name “gemeenschappelijke regelingen.”

The denominator counts domains, not municipalities. The report describes its 12,598-domain set as a selection and says the government lacks a complete, unified domain inventory. A repeated measurement of the same domains would show which endpoints changed and which entered or left the register.

That distinction matters to Holzbauer’s map. Municipalytics links local administrative units to public web, mail and DNS domains, then tests what those visible endpoints disclose. Its cross-country picture puts policy beside reachability. The Dutch figures add an institutional layer: a national target can travel unevenly through shared public arrangements, which the Forum says are often funded by other government bodies.

An IPv6-only user who cannot reach a public website does not care which level of government owns the budget line. The 2026 report shows that the policy signal did not produce the same web result across government categories. A matched set of municipal and shared-arrangement domains measured before and after the 2021 target would show how much of the Dutch change followed the policy itself.

Holzbauer’s call for European monitoring now has a clear specification: keep a dated panel of the same domains, identify the public body responsible for each endpoint, and show whether failed tests were fixed. Pair each result with the authority funding a joint service. A national average then comes with an audit trail instead of a flattering colour.
