4.255.90.245
Intelligence analysis classified IP 4.255.90.245 as a Microsoft Corporation (ASN 8075) infrastructure endpoint within the Microsoft Azure cloud environment. The asset maintained a Low Risk reputation score of 20 and operated as hosting infrastructure with open TCP ports 80 and 443. Network service analysis identified a TLS certificate issued for manage.devcenter.microsoft.com. Behavioral logs recorded no honeypot hits, enumeration strikes, or active attacker activity, though control plane data indicated route instability. Geolocation validation flagged a contradiction between the claimed Virginia origin and observed RTT physics measurements, resulting in a Very Low confidence classification. Security teams were advised to monitor the asset due to signal contradictions while maintaining the current low-risk posture.
