AS10991 CAPGE-HOSTING-MRO
Unclassified ARIN
Summary
Capgemini
enterprise hosting legacy
CAPGE-HOSTING-MRO is registered to Capgemini America, Inc., the US arm of the French IT services, consulting and outsourcing group. As the handle says, this is a hosting AS: the network behind Capgemini's managed infrastructure and outsourced application estate, not a corporate office network.
What it's used for
RIS sees 41 announced IPv4 prefixes covering 10,496 addresses, no IPv6, and 7 observed neighbours. Seven adjacencies rules out any carrier role. What makes this AS distinctive is the composition of the space: mostly /24s, drawn from both ARIN ranges (192.113., 204.153., 205.223., 206.208., 198.184.) and RIPE ranges (80.90., 80.253., 193.234., 194.11., 192.176.), announced together from one AS.
Scattered /24s from multiple RIRs is also the shape of an address broker, so it is worth saying why this is not one. The prefixes are registered to the holder rather than to unrelated third parties, the holder is a large, entirely findable multinational, and the sampled reverse DNS is first-party: mx.sii.fr.capgemini.com, a mail exchanger in the company's own French sub-zone. A global consultancy that has absorbed many national IT businesses over decades legitimately ends up holding blocks in several registries and announcing them from one hosting AS.
Notable
- The single rDNS sample is a mail relay, i.e. infrastructure. Everything visible here is server-side: managed hosting for client workloads and Capgemini's own shared services. There is no sign of end-user access space.
- The US-registered holder announcing European space with French-named infrastructure is a clean example of why registry country is a poor proxy for where a network actually operates.

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 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
