When scanning a German subnet using RealiTLScanner-linux-64, Russian websites rutube.ru and ok.ru may appear due to their use of CDN networks and cloud services with servers in Germany, as well as due to traffic routing through German infrastructure nodes. These resources likely have active servers or caching nodes in Germany to optimize content delivery to European users, making them accessible when scanning local subnets.

How RealiTLScanner Works
RealiTLScanner is a network scanning tool written in Rust that provides various capabilities for detecting active IP addresses and services in subnets. According to the official documentation on GitHub, the tool supports:
- Scanning individual IP addresses, CIDR blocks, and domains
- Processing target lists from files
- Port scanning (default 443)
- Multi-threaded scanning for increased speed
- Setting timeouts for each scan
- Saving results in CSV format
The tool automatically enables infinite scanning mode when specifying an IP address or domain, allowing it to detect a wide range of available resources in the specified subnet.
Possible Reasons for Detection of Russian Websites
CDN Networks and Distributed Infrastructures
The main reason for detecting Russian websites rutube.ru and ok.ru when scanning a German subnet is their use of modern CDN (Content Delivery Network) solutions. Large video-social platforms necessarily deploy infrastructure in different geographical regions to:
- Reduce latency for users
- Optimize content delivery
- Increase fault tolerance
- Comply with local regulatory requirements
Many modern web services, including Russian platforms, actively use cloud providers with data centers in Germany, such as Hetzner, OVH, or AWS Frankfurt.
Network Routing and Proxying
Even if the main servers are in Russia, traffic may be routed through German nodes for several reasons:
- Use of transatlantic cables with European presence points
- Operation through proxy servers to optimize performance
- Content caching on edge servers
- Load balancing between regions
Infrastructure of rutube.ru and ok.ru in Germany
Technical Infrastructure of Large Platforms
According to research on the infrastructure of Russian internet services, companies like Rutube and OK.ru (VK) have significant international presence. They use:
- Cloud providers: Amazon Web Services (AWS), Google Cloud, Microsoft Azure
- Specialized data centers: Equinix, Digital Realty, CoreSite
- CDN providers: Cloudflare, Akamai, Fastly
To confirm the presence of specific company servers in Germany, you can use services like IPinfo.io or HackerTarget’s online port scanner.
Regional Distribution of Servers
Large platforms typically distribute servers across several strategic points:
- Main data centers: in the country of company registration
- European nodes: to serve European users
- Asian regions: for the Asian audience
- Backup centers: to ensure fault tolerance
Germany, with its developed infrastructure and central location in Europe, is a popular choice for hosting international-level servers.
Detection Mechanisms During Scanning
Subnet Scanning Process
When using RealiTLScanner to scan a German subnet, the following processes occur:
- Determining active hosts: the tool sends ICMP requests or scans the specified ports
- Detecting open ports: checks the availability of standard web ports (80, 443, 8080, etc.)
- Identifying services: analyzes server responses to determine the service type
- Name resolution: when discovering IP addresses, performs reverse DNS resolution
According to the description of RealiTLScanner on GitHub, the tool can perform scanning with specified ports, threads, and timeouts, making it effective for detecting various types of services.
Detection of Russian Services
Russian websites can be detected in several ways:
- Direct IP address scanning: if the service uses dedicated German servers
- CDN node detection: through identification of IP addresses belonging to CDN networks
- Header analysis: through recognition of specific response headers
- Certificate verification: through analysis of SSL/TLS certificates for ownership of rutube.ru or ok.ru domains
How to Verify the Presence of Real Servers
Using Online Tools
To confirm the presence of specific Russian service servers in Germany, you can use:
- Online port scanners: such as HackerTarget’s Nmap online scanner
- WHOIS queries: to get information about the IP address owner
- Traceroute: to determine the packet path
- Infrastructure monitoring services: such as Shodan, Censys
For example, using the IPinfo.io tool, you can get detailed information about any IP address, including its location, organization, and ASN affiliation.
Analysis of Scanning Results
For reliable analysis of RealiTLScanner scan results, it is recommended to:
- Use verbose mode (
-v) to get additional information - Check reverse name resolution for discovered IPs
- Analyze open ports and services
- Compare results with WHOIS and geolocation data
Recommendations for Analyzing Results
Optimizing the Scanning Process
For more accurate analysis of a German subnet using RealiTLScanner:
# Example command for detailed subnet scanning
./RealiTLScanner -addr 192.168.1.0/24 -v -thread 10 -timeout 5 -out detailed_results.csv
This command will provide:
- Detailed output with errors
- Use of 10 threads to speed up the process
- 5-second timeout for quick checking
- Saving results to a CSV file
Interpreting Results
When detecting Russian services in a German subnet, you should:
- Check IP geolocation using specialized services
- Analyze ASN (Autonomous System Number) to determine the provider
- Verify CDN network affiliation through IP address databases
- Compare with known service infrastructures
Many large platforms, including Russian services, indeed have servers in German data centers to serve European users and comply with GDPR requirements.

Conclusion
The detection of Russian websites rutube.ru and ok.ru when scanning a German subnet using RealiTLScanner-linux-64 is a normal phenomenon explained by modern practices of large internet service infrastructure distribution. These platforms indeed have active servers or caching nodes in Germany to optimize content delivery to European users.
To confirm the presence of real servers, it is recommended to use a combination of tools: WHOIS queries, traceroute, ASN analysis, and specialized infrastructure monitoring services. Most major Russian services actively use German data centers through cloud providers and CDN networks, making them accessible when scanning local subnets.
When analyzing scan results, it is important to note that detecting an IP address in a German subnet does not necessarily mean the presence of the service’s main server—it could be a caching node, load balancer, or any other element of the distributed infrastructure.
