DNS records tell the internet where to find your services. Here are the most common types.
A Record
Maps a domain to an IPv4 address.
example.com A 198.48.63.241AAAA Record
Maps a domain to an IPv6 address.
CNAME Record
Creates an alias pointing to another domain.
www.example.com CNAME example.comMX Record
Specifies the mail server for your domain.
example.com MX 10 mail.example.comTXT Record
Stores text data for verification, SPF, DKIM, etc.
NS Record
Specifies the nameservers for your domain.
TTL
Time-To-Live — how long DNS resolvers cache the record. Lower TTL = faster propagation of changes, but more DNS queries.
