Summary

Conclusion Enablement

Netherlands · AI-generated

business connectivity netherlands

CONCLUSION is operated by Conclusion Enablement BV.

What it's used for

  • The address space carries corporate connectivity infrastructure, evidenced by netnames NL-CONCLUSION-20150713 and NL-CONCLUSION-CMC and registrants including Conclusion Team Connectivity and Conclusion Mission Critical B.V.
  • The AS announces 1536 IPv4 addresses across 2 prefixes and maintains 55 observed neighbours, a ratio indicating a transit or interconnection role rather than a large-scale access network.
  • Traffic from this AS consists of internal corporate data and mission-critical services for the Conclusion group, a provider of engineering and technology services.

Notable

  • Registrants align with the announcer, listing Conclusion Team Connectivity, Conclusion Enablement BV, and Conclusion Mission Critical B.V.
  • The address inventory is compact, consisting of one /22 and one /23 block, both located in the Netherlands.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 446 networks and 1,852 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
