Autonomous system
AS18563 CGINET-01
Unclassified ARIN
Summary
CGI Inc.
business enterprise canada consulting
CGINET-01 is the autonomous system for CGI Inc., a major global IT and business consulting firm.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by netnames like
CGI-GLOBAL-2,CGI-BLK-3, andCGI-GIS-ONT-2, as well as reverse DNS entries pointing tocognicase.netandcgitmsmdc.ca. - With 17,408 IPv4 addresses announced across 19 prefixes and only 5 observed neighbours, the ratio indicates a large internal corporate estate rather than a transit or access network.
Notable
- Registrants are consistent with the announcer, primarily listing CGI Inc., with some blocks registered to CGI Group and CGI GIS Telecom MDC.
- The address inventory is finely subdivided into numerous /23 and /24 blocks, reflecting site-by-site segmentation typical of a large multinational corporation.

Interconnection
Peering at a glance
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 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
