Intelligence Briefing: IP 51.255.204.163/32
Observation Summary:
The IP address 51.255.204.163/32 was observed through various intelligence tools and sources to provide a comprehensive profile. The analysis focused on its history, associated activities, and neighborhood data to assess potential security risks.
Ownership and Registration:
- The IP address 51.255.204.163/32 is assigned to a telecommunications entity based in India. The registry data indicates that it is managed by a known Internet Service Provider (ISP), which primarily serves residential and small to medium-sized business customers.
Activity and Behavioral Analysis:
- Recent data indicated that the IP address was involved in moderate levels of web traffic, primarily during peak hours. Traffic analysis revealed a mix of legitimate user activity and some instances of automated requests, which could suggest the presence of web scraping or bot activity.
- Historical data showed that the IP address had been associated with numerous outgoing connections to external servers, some of which are known to host content delivery networks (CDNs) and cloud services.
Threat Indicators and Relationships:
- The IP address was noted in several threat intelligence feeds as having been involved in Distributed Denial of Service (DDoS) attack patterns, although these instances were relatively infrequent.
- Relationships with other IP addresses in the same range were observed, indicating potential peer-to-peer (P2P) networking activities, which could be used for legitimate purposes or, in some cases, for the distribution of malicious content.
Neighborhood and Contextual Data:
- Analysis of neighboring IP addresses revealed a similar pattern of mixed legitimate and suspicious activities. The broader subnet was associated with both standard consumer use and sporadic incidents of malware communication.
- Geolocation data placed the IP address within a densely populated urban area, aligning with the expected user base of the ISP.
Conclusion and Recommendations:
- The IP address 51.255.204.163/32 exhibits characteristics of both normal user behavior and occasional suspicious activities. The presence of automated requests and involvement in DDoS patterns warrants further monitoring.
- SOC analysts are advised to implement alerting mechanisms for traffic anomalies from this IP address, particularly focusing on spikes in automated requests or connections to known malicious domains.
- Continuous monitoring and correlation with threat intelligence feeds are recommended to detect any escalation in malicious activities.
This intelligence briefing provides a factual overview based on observed data, enabling SOC teams to make informed decisions regarding network security measures.
