📚 How DNS Works (Plain English)

DNS (Domain Name System) is the internet's phonebook. When you type google.com in a browser, your computer asks a DNS server: "What IP address does this domain point to?"

DNS records are the database entries that answer those questions. Different record types answer different questions: A records give IP addresses, MX records specify mail servers, TXT records carry text like security policies.

Security uses: DNS records are essential for email security (SPF, DKIM, DMARC live in TXT records), detecting subdomain takeovers, verifying domain ownership, and troubleshooting connectivity issues.
