Intelligence Briefing: 23.210.73.151/32
Observation Date: 2026-09-15
Ownership: Akamai Technologies, Inc. (ASN 20940), AKAMAI
Network Role: Content Delivery Network (CDN), Web Server
Risk Score: 25 (Low Risk)
Summary:
Analysis of 23.210.73.151 confirmed the address belonged to Akamai Technologies, Inc. within the 23.192.0.0/11 block. The host operated as a CDN web server with open ports 80 and 443, resolving via forward DNS to `a23-210-73-151.deploy.static.akamaitechnologies.com`.
Threat Indicators:
No specific threat indicators were present. The host was not classified as a known attacker, spam source, or Tor exit node, and the blacklist count remained at zero. Behavioral logs showed zero WAF violations, enumeration strikes, or active attacker status. Neighborhood analysis classified subnet 23.210.73.151/24 as clean, with zero threat siblings among ten active peers.
Anomalies and Contradictions:
Control plane data indicated one DNSBL listing out of eight total lists and four BGP route changes in the preceding 30 days. A contradiction was identified between claimed geolocation (Cambridge, MA) and physics-based RTT measurements. DNS hygiene was rated Poor due to missing SPF and DMARC records. Operational confidence remained very low (0.2083) despite high data sufficiency (0.8333).
Recommendation:
Monitor. The system flagged signal contradictions and the presence of a DNSBL entry as reasons for continued observation. No active attacker classification was assigned.
