DNS Records

A ipv4 address-space before domain (ipv4). @ indicates no pre-address space http://test.domain.com
AAAA ipv6 address-space before domain (ipv6). @ indicates no pre-address space http://test.domain.com
CNAME subdomain-aliases By default, your address is http(s):// only. if you want users to be able to reach your site using www, you'll need to create a CNAME record. http://www.domain.com
NS DNS server to use Indicates a DNS server that is aware of your webserver. your domain-name-registrar may provide this, or if you are using a webservice like digitalocean, they may provide their own DNS servers. (after changing NS records, you'll need to wait up to 72 hours for updates to propagate across all nameservers).
