Summary
Atos Information Technology (Nuremberg)
hosting enterprise legacy
Atos Information Technology GmbH (ATOS-DE-NUREMBERG) — the German IT-services arm of Atos, formerly Siemens IT Solutions and Services, which Atos acquired from Siemens in 2011. Around 7,400 IPv4 addresses across eleven legacy 194.x blocks, routed out of Nuremberg.
What it's used for
- Managed IT outsourcing: Atos runs applications and infrastructure for client companies out of its own data centres, and the addresses go with the workloads.
- The rDNS is the evidence. The named hosts do not belong to Atos at all — they carry the domains of the customers whose systems sit there, from a German pay-TV operator's mail gateway to an asset manager's servers. Most of the space has no delegation, and the AS has only a couple of BGP neighbours.
Notable
- Customer hostnames in a hosting provider's space are not a broker signal. The prefixes are Atos's own legacy allocations, held under its own registry objects; the third-party names are simply outsourced workloads. It is the registration, not the hostname, that separates this from an address broker.
- Consequently these addresses geolocate to Atos's German facilities, not to the companies named in the reverse DNS. Anything reading the hostname as the location will place a pay-TV network and an investment firm inside a data centre they merely rent capacity in.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,781 prefixes, as published 2026-10-16. 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.
