DNS Patterns
Guide for DNS configuration, record management, DNSSEC, email authentication records, DNS debugging, and domain setup. Use when user needs to configure DNS records (A, AAAA, CNAME, MX, TXT, SRV, NS, SOA, CAA, PTR, NAPTR), set up DNSSEC signing/validation, configure SPF/DKIM/DMARC for email, debug DNS resolution with dig/nslookup/host, implement DNS load balancing or failover, set up GeoDNS or split-horizon DNS, configure DNS over HTTPS/TLS, manage private DNS zones, or troubleshoot DNS propagation. NOT for domain registration/purchasing, NOT for web server configuration (nginx/apache), NOT for SSL/TLS certificate setup (use ACME/certbot skills instead).
