IP address 3.5.105.9/32 is assigned to Amazon Data Services Northern Virginia (AS16509) within the 3.5.0.0/16 block. Geolocation data places the network in Columbus, Ohio, United States, though this may represent an approximate location. The host is identified as a Web Server on Amazon Web Services infrastructure; conflicting observations exist between the geolocation record and the routing operator designation. No active TLS endpoints were observed during probing, and a historical certificate record associated with the *.s3.us-east-2.amazonaws.com domain indicated a future validity period extending into 2027. DNS hygiene remains unassessed, with SPF, DMARC, and CAA checks returning as not checked, and DNSSEC status listed as unknown. The risk score is currently zero, yet the absence of specific indicators and the limited scope of observations do not confirm the absence of malicious activity or fully characterize the host's operational status. Corroboration through additional traffic analysis is recommended to validate the network role and rule out potential compromise.
