54.154.100.157
IP address 54.154.100.157/32 was identified as a web server within Amazon Web Services infrastructure (ASN 16509). Ownership records attributed the address to Amazon Technologies Inc., with geolocation data indicating London, GB, though sources disagreed on country assignment between GB and KR. DNS resolution confirmed the hostname ec2-54-154-100-157.eu-west-1.compute.amazonaws.com. The endpoint exposed HTTP and HTTPS services on ports 80 and 443. TLS inspection revealed a certificate issued by Sectigo RSA Organization Validation Secure Server CA (C=GB) for the Samsung Electronics domain (C=KR). No malicious indicators, blacklist entries, or known campaigns were associated with the address, and the reputation score was recorded as Low Risk (0). Due to conflicting geolocation and certificate country data, the asset was classified as Low Risk but recommended for monitoring to ensure consistency between infrastructure claims and certificate data.
