Observation History:
1. Activity Trends:
- The IP address has consistently been active over the past 12 months, with a noticeable increase in web traffic volume during the last quarter. This aligns with common patterns observed in web hosting environments.
- No significant spikes in outbound traffic were noted, which suggests the absence of typical command and control (C2) communication patterns often associated with malicious activity.
2. Web Services:

- Domain Associations:
- A number of domains associated with this IP have been flagged by various threat intelligence platforms for suspicious activity. These include domains that mimic well-known brands, often used in phishing attempts.
- Neighborhood Data:
- The neighboring IP addresses also belong to the same hosting provider, with some hosting sites flagged for hosting malware or suspicious content. This suggests a potential risk of co-hosting with malicious actors, which could lead to collateral damage or association risks.
Actionable Intelligence:
- Monitoring:
- Continuous monitoring of HTTP traffic patterns for anomalies that deviate from typical CDN or web service behavior is recommended. This could help identify potential misuse or compromise of hosted sites.
- Alerts and Indicators:
- Implement alerts for any new domains associated with this IP that exhibit characteristics of phishing or other malicious activities, such as rapid domain registration and use of brand-similar names.
- Assessment:
- Consider conducting a more in-depth assessment of the domains hosted under this IP to identify any potential security risks or policy violations. This may include scanning for common vulnerabilities or malicious content.
Conclusion:
IP 51.195.183.211/32 is part of a shared hosting environment with a mixed reputation. While current observations do not indicate direct malicious activity, the presence of potentially suspicious domains suggests a need for vigilant monitoring and proactive threat hunting.
