DNS (Domain Name System) is the backbone of the internet, translating human-readable domain names into IP addresses that computers use to communicate. This free DNS lookup tool lets you inspect all major record types for any domain, helping you diagnose configuration issues, verify email setup, and understand how a domain is structured.
Understanding DNS Record Types
A Records map a domain to an IPv4 address. This is the most fundamental DNS record, directing traffic to the correct server. AAAA Records serve the same purpose but for IPv6 addresses, supporting the next-generation internet protocol.
MX Records (Mail Exchange) specify which mail servers handle email for a domain and their priority. If you're troubleshooting email delivery, checking MX records is often the first step. NS Records (Name Server) indicate which DNS servers are authoritative for a domain.
TXT Records hold arbitrary text data and are commonly used for email authentication (SPF, DKIM, DMARC), domain verification, and security policies. CNAME Records (Canonical Name) create aliases, pointing one domain name to another. SOA Records (Start of Authority) contain administrative information about the DNS zone, including the primary name server and zone serial number.
