Summary

KZV Nordrhein

Germany · AI-generated

business healthcare dental germany

KZVNR is operated by KZV Nordrhein (Kassenzahnärztliche Vereinigung Nordrhein).

What it's used for

  • The space carries the internal network of the North Rhine Dental Association, as indicated by the netname KASSENZAHNAERZTLICHE-VEREINIGUNG-NORDRHEIN-NET and registrant KASSENZAHNAERZTLICHE VEREINIGUNG NORDRHEIN.
  • The AS announces 512 IPv4 addresses in a single /23 prefix and one IPv6 /48 prefix, with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal administrative and operational communications for the statutory dental association, which manages dental care contracts and professional regulations for dentists in the North Rhine region.

Notable

  • The RDAP registrant KASSENZAHNAERZTLICHE VEREINIGUNG NORDRHEIN matches the AS holder, confirming direct ownership of the address space.
  • The address inventory is compact, consisting of a single contiguous IPv4 block and a single IPv6 prefix, typical of a specific organizational site or department.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
