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
