## INTELLIGENCE CONCLUSION

IP 161.35.101.10 represents a low-risk DigitalOcean cloud infrastructure endpoint with no active services and no current malicious behavior. The single blacklist listing appears historical or contextual rather than indicative of active abuse. However, recent port scanning activity and the presence of two medium-risk neighbors in the same /24 subnet warrant continued monitoring. No immediate blocking action is recommended, but maintain visibility on this IP in threat monitoring systems.
