About this network

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-USA and CRITEO-USA-2 and 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.
