3.19.98.183
IP address 3.19.98.183 was identified as an Amazon Web Services EC2 instance associated with ASN 16509. The host resided in Columbus, Ohio, within the 3.0.0.0/9 CIDR block. Network scans revealed an open TCP port 443 serving HTTPS traffic, responding with an HTTP status code 403 over HTTP/2.0.
The TLS certificate was issued by Thawte for the domain *.samsungqbe.com, attributing the host to Samsung Electronics CO., LTD. A low-risk reputation score of 25 was assigned, with a clean neighborhood classification in the 3.19.98.183/24 subnet. However, data inconsistencies were observed during the assessment. Geolocation sources conflicted between the United States and South Korea, while the IP appeared on one DNS blacklist out of eight total lists queried.
Behavioral indicators showed no active attacker activity, zero incidents, and no known campaigns. Due to conflicting geolocation signals and the single DNSBL listing, the recommended action was to monitor the IP address for changes rather than implementing immediate blocking rules.
