173.79.0.252
Intel analysts assessed IP 173.79.0.252/32 as a Verizon Business endpoint within the 173.64.0.0/12 block, resolving to a FIOS hostname in Washington DC. The profile classified the host as a "Suspicious Host" despite a Low Risk reputation score of 25.
Technical scans confirmed the address had no open services and was not identified as a CDN, proxy, or cloud endpoint. While the threat indicator lists remained empty, the control plane data showed one DNS blacklist listing out of eight total lists checked. A critical anomaly identified was that the claimed geolocation contradicted RTT physics measurements, recording a 31ms RTT against a minimum possible 125.9ms for the claimed distance.
The behavioral analysis recorded no known attacks, honeypot hits, or enumeration strikes. Given the Very Low confidence score and signal contradictions, the profile recommended monitoring the address rather than immediate blocking.
