Summary

Klaver IT

Netherlands · AI-generated

business netherlands small

KLAVER-IT is operated by Klaver IT, a Dutch IT professional service.

What it's used for

  • The address space carries a single IPv4 prefix 91.213.178.0/24 and one IPv6 prefix 2001:67c:50::/48, with the netname KLAVER-IT and registrant Klaver IT; Michiel Klaver.
  • The network announces 256 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large access provider.
  • Traffic from this AS consists of web and API endpoints for an IT professional service, supporting client projects and online presence.

Notable

  • The registrant Klaver IT; Michiel Klaver matches the AS handle KLAVER-IT and the operator identity.
  • The address inventory is minimal, consisting of a single /24 block and a /48 IPv6 prefix, typical of a small independent IT consultancy.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
