sin3-cb.adnxs.com
Category: Not Recommended Site
Description of sin3-cb.adnxs.com
sin3-cb.adnxs.com appears to be a subdomain within the adnxs.com domain, which is associated with digital advertising and ad-serving infrastructure. The available category data suggests the host is related to advertisements and information technology rather than a consumer-facing website with editorial or retail content.
Based on the domain structure, long registration history, and enterprise registrar usage, this host likely serves a technical role inside a larger advertising platform operated by AppNexus Australia Pty Limited. Such subdomains are commonly used for content delivery, ad bidding, tracking, or campaign-serving functions rather than as standalone public websites.
Safety Assessment for sin3-cb.adnxs.com
At the time of this scan, no security engines reported detections for this host, and the malware scan did not identify any flagged files, malicious links, or suspicious iframes. The domain was also not listed by the checked blacklist and threat-database sources based on the available data.
Some classification data labels the host as an advertising-related or not-recommended site, which may reflect content type, tracking behavior, or suitability concerns rather than confirmed malware activity. Because this appears to be an advertising infrastructure subdomain rather than a traditional website, reputation signals may vary depending on network policies and content-filtering rules.
Based on available scan data, no significant threats were detected at the time of this scan.
Technical Description
The host presented a valid SSL/TLS certificate issued by DigiCert Inc., with expiration listed as 2026-10-26. It resolves to an IP address in Sydney, Australia and appears to be hosted by AppNexus Australia Pty Limited, using nginx/1.25.5 as the web server. The domain itself is mature, with a registration age of roughly 17 years and management through an enterprise-focused registrar.
DNSSEC appears to be unsigned, which is not uncommon but means DNS responses may not benefit from DNSSEC validation. No direct technical indicators of compromise were reported in the provided scan results at the time of analysis.
