Summary

Atos Information Technology GmbH

Germany · AI-generated

business enterprise it germany

The AS handle ATOS-ESSEN-AS is held by Atos Information Technology GmbH.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by netnames ATOS-NET and Atos-DE-RGN associated with the registrant AtosDE Role.
  • The AS announces 2560 IPv4 addresses across 3 prefixes, with a single observed neighbour, indicating a small, self-contained internal corporate estate rather than a transit or access network.

Notable

  • Registrants for all announced prefixes are consistent with the announcer, listing AtosDE Role and Atos Information Technology GmbH.
  • The inventory consists of three distinct IPv4 blocks: 194.145.88.0/21, 194.8.121.0/24, and 194.145.87.0/24, all located in Germany.

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.
