52.209.135.104
Intelligence Briefing: IP 52.209.135.104/32
The IP address was identified as low-risk infrastructure owned by Amazon Data Services Ireland Limited (ASN 16509). It resolved to an EC2 instance within the 52.208.0.0/13 block and operated as a web server running Apache. Services included HTTP (port 80) and HTTPS (port 443). A TLS certificate was observed for Samsung Electronics CO.,LTD (KR), issued by Sectigo. While primary geolocation data indicated Dublin, IE, the TLS certificate subject claimed origin in South Korea, resulting in geo-validation contradictions. No threat indicators, blacklists, or malicious activity were recorded. Risk scores remained at zero with a reputation classification of Low Risk. Due to mixed signals regarding geo-location versus certificate data, the address was classified for monitoring.
