Summary
Criteo
business advertising infrastructure
AS-CRITEO is operated by Criteo Corp., a global commerce intelligence and online advertising platform.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by netnames
CRITEO-USAandCRITEO-USA-2and registrants listing "Criteo Engineering" and "Criteo Network Operations Center". - The AS announces 1024 IPv4 addresses across 4 prefixes and 8 IPv6 prefixes, with 18 observed neighbours; this ratio of modest address space against a moderate number of peering partners indicates a business network with significant upstream and peering connectivity rather than a transit provider.
Notable
- All registrants for the announced IPv4 prefixes are Criteo Corp., matching the AS holder and confirming the space is owned and operated by the company.
- The address inventory consists of four /24 IPv4 blocks and eight IPv6 prefixes, including /48s and a /46, reflecting a finely subdivided internal corporate estate for site-by-site segmentation.
- Criteo Corp. is a US subsidiary of Criteo S.A., the parent company of the global commerce intelligence platform.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
