98.136.158.207
The IP address 98.136.158.207 exhibited a low-risk reputation profile with a risk score of 20. Ownership records attributed the address to Yahoo Holdings Inc. under ASN 36647 within the 98.136.0.0/14 block. Network scans detected no open ports, classifying the target as firewalled with no active services. DNS analysis confirmed reverse resolution to a Yahoo hostname with valid SPF and DMARC records. Threat intelligence feeds did not identify any associated campaigns, blacklisting, or abuse history. However, geolocation data presented a contradiction where the claimed Washington, US location did not align with observed RTT physics measurements, which indicated a distance of 7824km against a minimum possible RTT of 156.5ms. The immediate subnet maintained a clean classification with zero abuse density. Operational guidance advised monitoring the asset due to signal contradictions, assigning a low severity level.
