A DNS record is a data entry stored in an authoritative DNS server that provides information about a domain. Every domain has a set of DNS records that tell the internet how to route traffic, deliver email, verify ownership, and more.
Common DNS Record Types
| Record Type | Purpose | Example |
|---|---|---|
| A | Maps domain to IPv4 address | example.com → 93.184.216.34 |
| AAAA | Maps domain to IPv6 address | example.com → 2606:2800:... |
| CNAME | Alias pointing to another domain | www.example.com → example.com |
| MX | Mail exchange servers | Who receives email for example.com |
| TXT | Arbitrary text (SPF, DKIM, verification) | v=spf1 include:... -all |
| NS | Authoritative nameservers for the domain | ns1.example.com |
| PTR | reverse DNS (IP to domain) | 34.216.184.93.in-addr.arpa → example.com |
| SOA | Start of authority (zone metadata) | Primary NS, admin email, serial |
| CAA | Which CAs can issue SSL/TLS certs for domain | letsencrypt.org only |
