📚 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.

Frequently asked questions

What are DNS records?

DNS records are entries in the Domain Name System that map a domain to an IP address or configure mail and other services. Common types include A (IPv4), AAAA (IPv6), MX (mail), and TXT (verification).

Why do I see different results from different resolvers?

DNS changes propagate gradually across the internet. Results can differ because resolvers cache old data until the TTL expires.

What does TTL mean?

TTL stands for Time to Live. It tells resolvers how many seconds to cache a record before fetching a fresh copy.

How do I check if a DNS change has propagated?

Look up the record repeatedly and compare timestamps. You can also check from different geographic locations using online tools.
