Basic Domain Settings

A Records

An A record maps an IPv4 address to a domain name. This determines where to direct any requests for a domain name.

AAAA Records

An AAAA record, also called a Quad A record, maps an IPv6 address to a domain name. This determines where to direct requests for a domain name in the same way that an A record does for IPv4 addresses.

CNAME Records

A CNAME record defines an alias for an A record; it points one domain to another domain instead of to an IP address. When the associated A record’s IP address changes, the CNAME will follow to the new address.

MX Records

An MX record specifies the mail servers responsible for accepting email on behalf of your domain. Providers often make multiple name servers available so that if one is offline, another can respond. Each server needs its own MX record.

NS Records

An NS record specifies the name servers, or servers that provide DNS services, for a domain or subdomain. You can use these to direct part of your traffic to another DNS service or to delegate DNS administration for a subdomain.
