Summary
Atos Information Technology (Singapore)
enterprise hosting legacy
AS9890 (ATOSINFOTECH-SG-AP) is held by Atos Information Technology (Singapore) Pte Ltd, the Singapore arm of Atos SE, the French IT services and managed-outsourcing group. This is a managed-services network: Atos runs infrastructure on behalf of corporate clients, and this AS is where the Asia-Pacific end of that lands.
What it's used for
RIS sees 16 IPv4 prefixes carrying 8,448 addresses, 1 IPv6 prefix (2a00:ad87:4600::/48), and 2 observed BGP neighbours. Two neighbours rules out any transit role; the AS buys connectivity and announces its own and its customers' space behind it. The give-away is whose space it announces. Alongside its own 203.95.64.0/20-area blocks, AS9890 originates /24s out of 194.138.x — part of a large block registered to Siemens — and out of 143.99.x and 155.45.x. Addresses in 194.138.240.0/24 carry siemens.com hostnames. That is the fingerprint of an outsourcing arrangement: Atos operates the network, the client owns the addresses.
Notable
- Atos acquired Siemens IT Solutions and Services in 2011, which is the historical reason a French IT-services company announces Siemens-registered address space from a Singapore AS. This is a clean example of why registrant and operator can diverge.
- It is also a clean example of the reverse-DNS rule:
siemens.comPTRs inside this AS do not make it Siemens' network. They show what the space carries, not who holds the ASN. - The mixture of ARIN-, RIPE- and APNIC-region blocks in a single small AS looks superficially like the address-broker pattern, but here it has an ordinary explanation — a global outsourcer serving multinational clients whose address space was allocated wherever their headquarters happens to be.

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 2026-10-12, 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: 436 networks and 1,769 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.
