# Your domain on your VPS, without writing a record

> Point a domain at your instance from the console: the records are written for you, and you see what changes before it changes.

*Published on September 24, 2026*

Pointing a domain at a server has always meant the same thankless work: find the IP address, open the zone editor, create an A, an AAAA, a www, remember the CAA. Miss one and the site does not answer; overwrite one and the email stops.

A **Domain** tab now appears on your instances. You pick a domain you own, you say what the server is for, and the records are written from the instance's own addresses. You never open the zone editor.

## You see it before it changes

This is the part that matters most, and the part missing almost everywhere else.

Before anything is written, the preview shows every record: the ones that will be created, the ones already correct, and the ones that will be **replaced — with the value they hold today beside the new one**.

One case makes this worth having. If your email is hosted elsewhere — Google, Microsoft, anyone — pointing MX at your VPS stops your mail from arriving. Plenty of tools do it silently. Here your current MX records appear as a replacement, in plain sight, and you decide.

## Three profiles, depending on what the server does

| Profile             | Writes                                                    | Leaves alone |
| ------------------- | --------------------------------------------------------- | ------------ |
| A website           | A, AAAA, www, CAA                                         | your email   |
| A website and email | the above, plus mail, MX, SPF, DMARC, and the reverse DNS | —            |
| Cloudron            | my and the `*` wildcard, CAA                              | your email   |

The Cloudron profile only appears on an instance running Cloudron. It writes the two records that panel needs to give each application its own subdomain — without them, it does not work.

## The reverse DNS your registrar cannot set

The email profile also sets the reverse DNS of the IP address. It is the only record on this list no registrar can create for you: the address is ours. Mail servers check it before accepting your messages, and its absence is a common reason for mail landing in spam.

## When the address changes

A reinstall or a migration can change the instance's primary address. Attached domains follow: their A and AAAA records are rewritten to the new address, with nothing to do.

## Getting started

The **Domain** tab is available on your instances from the [console](https://console.onetsolutions.net/compute/instances). It offers the domains in your organization whose DNS zone we host.
