# Manage DNS records

## Manage DNS records

DNS records connect your domain to servers and services.

### Common record types

* **A**: points a name to an IPv4 address.
* **AAAA**: points a name to an IPv6 address.
* **CNAME**: alias one name to another name.
* **MX**: mail routing.
* **TXT**: verification and email auth (SPF/DKIM/DMARC).

### Typical setups

#### Website on a VPS

* `A` record for `@` → your VPS IPv4
* Optional `A` record for `www` → your VPS IPv4, or `CNAME www → @`

#### Email deliverability

* SPF (TXT)
* DKIM (TXT)
* DMARC (TXT)

{% hint style="warning" %}
Bad MX/TXT records can break email. Make one change at a time.
