Intelligence regarding IP 141.136.111.202 identified the address as a low-risk endpoint (Risk Score 25) associated with NACNET-EU (ASN 3257) within the 141.136.111.0/24 block. Reverse DNS resolution returned ae0.cr13-lon8.ip4.gtt.net, indicating infrastructure hosted by GTT. Network probing revealed the host as firewalled with no open services, and the address was not identified as a known attacker, spam source, or Tor exit node.
Contradictory data points emerged during validation. Geolocation tools assigned a Boston, US location, yet Round-Trip Time measurements (87.6ms average) contradicted the physics of a 7,626 km distance, suggesting the infrastructure physically resided in London. Route stability was flagged as false, and one DNSBL listing was recorded out of eight total lists.
Although the overall reputation was classified as Low Risk, the system tagged the host as Suspicious with a low confidence score. The neighborhood analysis indicated a mostly clean classification for the subnet, though two threat siblings were present. Operational guidance recommended monitoring the address due to signal contradictions, maintaining a low severity level.
