Summary

Clausjuergens EDV-Beratungsgesellschaft mbH

Germany · AI-generated

business it-services germany

CLEB-AS is operated by Clausjuergens EDV-Beratungsgesellschaft mbH.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname CLJ-INET and reverse DNS entries such as CLhost064.clausjuergens.de and CLhost127.clausjuergens.de.
  • The AS announces a single IPv4 prefix (193.100.167.0/24) comprising 256 addresses with one observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • As an IT consulting firm, the traffic consists of office workers and internal web/API endpoints for the company's own operations.

Notable

  • Registrants align with the announcer, listing Clausjuergens EDV-Beratungsgesellschaft mbH and Clausjuergens Network Operators.
  • The address inventory is a single /24 block, consistent with a small corporate estate.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
