DNS Lookup — What the Records Mean

DNS (Domain Name System) is the internet's phone book, translating domain names into IP addresses. Every domain has DNS records that control how traffic is handled.

A and AAAA Records

A records map a domain to an IPv4 address. AAAA records map to IPv6. These are the most fundamental records — they tell browsers where to connect.

MX Records — Mail Servers

MX records specify which servers handle email for a domain. Each has a priority — lower numbers are tried first. Essential when debugging email delivery issues.

TXT Records

TXT records store text used for domain verification (Google, Apple), SPF anti-spam policies, DKIM keys, and DMARC policies.

CNAME Records

A CNAME creates an alias from one domain to another. For example, www.example.com might CNAME to example.com. CNAMEs cannot coexist with other records at the domain root.
