Summary

Landkreis Kassel

Germany · AI-generated

government municipal hesse

The AS handle LANDKREISKASSEL is held by Landkreis Kassel, the administrative district government in Hesse, Germany.

What it's used for

  • The address space is registered under the netname DE-LANDKREISKASSEL-20190925 with registrants including "Landkreis Kassel RIPE Hostmaster" and "Landkreis Kassel", indicating internal government infrastructure.
  • The AS announces 1024 IPv4 addresses in a single /22 prefix (45.157.144.0/22) and one IPv6 prefix (2a13:f000::/32), with only 1 observed neighbour, consistent with a small, self-contained municipal network rather than a transit or access provider.
  • Traffic from this AS consists of internal administrative, public service, and municipal IT endpoints for the district government and its subordinate offices.

Notable

  • Registrants align directly with the announcer, naming "Landkreis Kassel RIPE Hostmaster" and "Landkreis Kassel" for the sole announced prefix.
  • The address inventory is compact and uniform, comprising one IPv4 /22 and one IPv6 /32, with no fragmentation or external leasing evident.

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 1,779 prefixes, as published 2026-10-24. 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.
