Summary

Atos

Germany · AI-generated

business it-services corporate

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

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by netnames such as ATOS-IT-SOLUTIONS-AND-SERVICES-GMBH, Eviden-Germany-NET, and TERAPORT-NET.
  • With 28,416 IPv4 addresses across 13 prefixes and only 9 observed neighbours, the inventory represents a finely subdivided internal corporate estate rather than a transit or access network.

Notable

  • Registrants are consistent with the announcer, primarily listing Atos Information Technology GmbH and Atos IT Services GmbH, with one prefix registered to Atos Admin-C Role.
  • The netname Eviden-Germany-NET reflects the rebranding of Atos's IT services division to Eviden, a subsidiary of Atos SE.
  • The inventory consists of 13 IPv4 prefixes and 1 IPv6 prefix, all located in Germany, indicating a consolidated corporate footprint.

Reputation

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
