DNS Protocol Skill
Expert skill for DNS protocol implementation, server configuration, and DNS-based service discovery.
Capabilities
- DNS Query Execution: Execute dig/nslookup queries and interpret results comprehensively
- Record Type Analysis: Work with all DNS record types (A, AAAA, CNAME, MX, TXT, SRV, NS, SOA, PTR)
- DNS Server Configuration: Configure BIND, CoreDNS, and other DNS servers
- DNSSEC Implementation: Implement and validate DNSSEC signing and verification
- DNS Traffic Analysis: Analyze DNS traffic patterns and detect anomalies
- Service Discovery: Design DNS-based service discovery (SRV records, DNS-SD)
- Zone Management: Manage DNS zones, transfers, and delegation
- TTL Optimization: Optimize TTL values for different use cases
