DNS records explained
What A, AAAA, CNAME, MX, TXT and NS records mean and when you change them.
DNS is the internet's "phone book": it turns a domain name into a server address and tells where email goes. Records live in your domain's zone, and you edit them in cPanel with Zone Editor (if you use our nameservers).
| Record | What it is for |
|---|---|
| A | Connects a name (e.g. yourdomain.com) to the server's IPv4 address. |
| AAAA | Same, but with an IPv6 address. |
| CNAME | An alias: one name points to another name (e.g. www to yourdomain.com). |
| MX | Defines which server receives the domain's email; it has a priority. |
| TXT | Text data, most often SPF, DKIM, DMARC and ownership checks. |
| NS | Lists the domain's nameservers. |
Good to know#
- A record name without a trailing dot is automatically completed with your domain in cPanel.
- A CNAME cannot exist on the same name as another record (e.g. A or MX).
- Every record has a TTL, the time in seconds a value is cached. A lower TTL means a faster change.
