52.123.187.102
Intelligence analysis was conducted on IP address 52.123.187.102/32. The address is attributed to Microsoft Corporation (ASN 8075) within the ARIN registry, mapped to CIDR block 52.120.0.0/14. Network role classification identified the infrastructure as Microsoft Azure CloudCompute.
Active services included TCP ports 80 and 443. TLS certificates were observed for *.trouter.teams.microsoft.com, signed by Microsoft TLS G2 RSA CA OCSP 10. HTTP/2.0 was enabled. The address carried a Low Risk reputation with a risk score of 15 and zero blacklist associations. No known campaigns, honeypot hits, or WAF violations were detected during observation from 2026-09-03 to 2026-09-23.
A geolocation contradiction was recorded. While consensus placed the host in Virginia, USA, RTT measurements indicated a distance of 6379.9 km, contradicting the minimum possible RTT for that distance (127.6ms). RPKI validation returned a valid state.
The intent was classified as Legitimate Infrastructure. However, due to signal contradictions and low confidence metrics (0.2636), the recommendation was to Monitor. The address resides in a mostly clean subnet (52.123.187.0/24) with an abuse density of 0.0833.
