DNS translates names such as example.com into the addresses and services that computers use. A domain's authoritative nameservers publish its DNS zone.
Common records
- A/AAAA: point a name to an IPv4 or IPv6 address
- CNAME: point one hostname to another hostname
- MX: identify mail servers
- TXT: store verification and email-authentication data such as SPF, DKIM, and DMARC
- NS: delegate a domain or subdomain to nameservers
DNS changes are cached according to TTL values. Edit DNS only where your authoritative nameservers are managed.
