128.241.16.9
IP 128.241.16.9 was identified as an address within the 128.241.0.0/16 block owned by NTT America, Inc. (AS2914). The profile assigned a Low Risk reputation with a risk score of 25. Control plane analysis showed the BGP route was not stable over a 30-day period, recording two changes, while RPKI state remained valid.
Geolocation data placed the host in the United States at coordinates 37.75, -97.82. However, geo-validation measurements flagged a contradiction where the claimed distance of 7,626 km conflicted with the measured RTT of 62ms, as the minimum possible RTT for that distance exceeded 152 ms. DNS records indicated an SPF record was present, but DMARC and DNSSEC validations were missing. Forward resolution was not confirmed, though a PTR record resolved to ae-2.r00.dllstx15.us.to.gin.ntt.net.
Threat intelligence feeds returned no known campaigns, blacklists, or active attacker indicators. The neighborhood assessment classified the subnet as clean with zero threat siblings. Behavioral analysis recorded no honeypot hits or WAF violations. Despite the low-risk reputation, the overall confidence score remained at 0.125 due to data sufficiency constraints. Recommendations indicated a Monitor action with low severity, citing signal contradictions present in the dataset.
