23.211.136.103
The IP address 23.211.136.103/32 was identified as part of the Akamai Technologies, Inc. (ASN 20940) network infrastructure, operating within the 23.192.0.0/11 block. The host functioned as a CDN Web Server, responding on standard HTTP and HTTPS ports. The profile assigned a Low Risk reputation (score 25) with zero observed threat indicators, blacklist entries, or known campaign associations. While the subnet neighborhood was classified as clean with no malicious siblings, the geolocation data presented a contradiction between the claimed Boston, MA location and RTT physics measurements, resulting in a Very Low overall confidence score. DNS hygiene was rated Poor, lacking SPF and DMARC records. The recommended action was to monitor the asset for changes, acknowledging the presence of signal contradictions despite the infrastructure's clean classification.
