52.179.73.34
IP 52.179.73.34 is associated with Microsoft Corporation (AS8075) within Microsoft Azure infrastructure. Observation history from 2026-09-14 to 2026-09-23 indicates the endpoint functions as a web server with HTTPS enabled on port 443, serving a certificate for in.applicationinsights.azure.com.
Threat assessment classified the address as Low Risk with a risk score of 25. No known attacker indicators, blacklist entries, or malicious behavior were detected during the analysis period. DNS hygiene included SPF and DMARC records, though DNSSEC was not validated. One DNSBL listing was noted among eight total checks.
However, validation flagged a contradiction between claimed geolocation (US-MA) and RTT physics measurements, and route stability was marked as inconsistent. The system recommended ongoing monitoring due to these signal contradictions and low confidence metrics (0.2417). No immediate firewall rules were generated.
