Summary

CGI

United States of America · AI-generated

business it-services enterprise

The AS handle PHX-CGIAM is held by CGI Technologies and Solutions Inc.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames such as CGI-PDC-03, CGI-US, and DAL-143.
  • The AS announces 6,656 IPv4 addresses across 4 prefixes and 2 IPv6 prefixes, with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of office workers and internal IT endpoints for CGI’s global IT services operations, including SaaS and ERP solutions.

Notable

  • Registrants align with the announcer, listing CGI Group - TX, CGI TECHNOLOGIES AND SOLUTIONS INC, and CGI Inc. across the announced prefixes.
  • CGI acquired Stanley, Inc. in 2010, integrating its IT services operations into the broader CGI Group structure.
  • The inventory is finely subdivided into four distinct IPv4 blocks, reflecting site-by-site segmentation typical of a large corporate estate.

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 1,779 prefixes, as published 2026-10-24. 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.
