172.68.52.21
Intelligence Briefing: 172.68.52.21/32
Summary: The target IP was associated with Cloudflare, Inc. (ASN 13335, CLOUDFLARENET) and identified as US-based infrastructure in Boston, MA. Reputation analysis returned a Low Risk score of 25. The address functioned as a Content Delivery Network (CDN) with no open ports or active services observed.
Threat Indicators: No known attacker indicators, spam sources, or threat feed matches were found. The address was listed on one DNS blacklist out of eight total lists queried. No known campaigns were correlated.
Network and Routing: BGP routing originated from ASN 13335 with the prefix 172.68.52.0/24. Route stability was marked as false. A geolocation validation check noted a contradiction between the claimed Boston location and RTT physics measurements (17ms RTT vs 113.3ms minimum).
Recommendation: SOC analysts should treat inbound traffic as legitimate CDN infrastructure. The single DNSBL listing warrants internal verification, but the overall profile supports the classification of this IP as benign web infrastructure.
