Target 52.12.177.187 resides within the 52.0.0.0/10 block assigned to Amazon Technologies Inc. (AS16509) under the registration name AT-88-Z. Geolocation data indicates the infrastructure is located in the United States and operated by Amazon.com, Inc., US. Network role classification identifies the host as part of Amazon Web Services infrastructure, specifically functioning as a CloudCompute web server. Ownership records list the routing operator as AMAZON-02, confirming the association with AWS services.
Defensive hygiene assessments returned no evaluated checks for DNSSEC, SPF, DMARC, or CAA, with statuses recorded as unknown or not checked. A TLS probe targeted the certificate associated with *.execute-api.us-west-2.amazonaws.com, issued by Amazon RSA 2048 M04. The certificate was historically valid with a recorded expiration window between 2026-07-19 and 2027-02-01, though the probe status is currently unknown and marked as stale. The risk score is zero, and the host is not flagged as bogon, residential, proxy, or Tor-related. No conflicting geolocation or ownership indicators were observed. Monitoring is recommended to corroborate current service activity given the stale certificate data and lack of real-time TLS endpoint verification.
