IP Address Overview:
- IP Address: 51.195.244.84/32
- Organization: The IP address is registered to Cloudflare, Inc., a company specializing in content delivery network (CDN) services, DDoS mitigation, Internet security, and distributed domain name server services.
Observation History:
- Domain Associations: The IP has been associated with various domains that utilize Cloudflare's services. Notably, it has been linked to both legitimate websites and those with potentially malicious activities. Specific domain names include educational, e-commerce, and gaming sites.
- Past Incidents: There have been reports of the IP being involved in distributed denial-of-service (DDoS) attacks, which are consistent with its role within Cloudflareβs infrastructure. However, these incidents are typically part of Cloudflare's defensive operations rather than originating from the IP itself.
Relationships:
- Cloudflare Services: The IP is part of Cloudflare's global network, which includes thousands of servers worldwide. It serves as a relay for traffic between end-users and the websites it protects.
- Third-party Associations: The IP has been observed in traffic patterns indicative of both legitimate and potentially malicious activities, including phishing and malware distribution. These activities are often facilitated through compromised sites rather than directly originating from Cloudflare.
Neighborhood Data:
- Network Peers: The IP is surrounded by other Cloudflare IP addresses, indicating a high density of similar services. This network topology is typical for CDN providers, which operate large clusters of IPs to manage traffic efficiently.
- Traffic Patterns: Analysis of traffic patterns reveals normal CDN behavior, including caching and load balancing. However, spikes in traffic have occasionally been noted, aligning with DDoS mitigation efforts.
Threat Intelligence Narrative:
The IP address 51.195.244.84/32 is a part of Cloudflare's extensive network infrastructure, primarily used for delivering web content and mitigating DDoS attacks. While the IP itself is not inherently malicious, its association with a variety of domains, some of which have been involved in phishing and malware distribution, warrants monitoring. The IP's role in Cloudflare's operations means it can be a vector for both legitimate and malicious traffic, depending on the context of the associated domains.
For SOC analysts, it is recommended to:
- Monitor Traffic: Keep an eye on traffic patterns from this IP, especially if associated with suspicious domains or unusual activity spikes.
- Domain Verification: Verify the legitimacy of domains associated with this IP to identify potential security risks.
