DNS Resolution Process Visualization

Follow the complete DNS resolution process interactively, from initial client request through recursive resolvers to authoritative nameservers. This visualization helps security professionals understand each step of DNS queries for network analysis and monitoring.

Key Learning Points

• Complete Resolution Chain: See how DNS queries traverse from client through stub resolver, recursive resolver, root nameservers, TLD servers, and finally to authoritative nameservers
• Query Types: Understand the difference between A, NS, and other DNS record queries
• Security Implications: Learn what information is logged at each step and how to monitor for suspicious patterns
• Caching Behavior: Observe how DNS responses are cached at multiple levels to improve performance

Use Cases for Security Analysis

• Traffic Analysis: Understanding normal DNS patterns vs. suspicious behavior
• DNS Tunneling Detection: Recognizing abnormal query patterns that might indicate data exfiltration
• Network Monitoring: Knowing which servers and logs to monitor for comprehensive DNS visibility
• Incident Response: Tracing DNS queries during security investigations

This interactive visualization complements the DNS Security Analysis Series by providing hands-on experience with the concepts covered in the written material.
