A domain whose DNS zone we host can be pointed at a VPS from the instance itself: you pick the domain, say what the server is for, and the records are written from the instance’s own addresses.
Prerequisites
  • A VPS with OnetSolutions
  • A domain in the same organization, active, with its DNS zone hosted here

​
Point a domain at the instance

1

Open the Domain tab

From your instance, open Domain. It lists the domains already pointing at this server, and the ones that can.
2

Pick the domain

Only domains in this organization, active and with a zone hosted here, are offered. A domain already pointing at another instance is not: a name resolves to one server.
3

Say what the server is for

The profile decides which records are written. See the table below.
4

Read the preview, then apply

Nothing is written before you have seen it. Each record is shown as created, replaced — with the value it holds today beside the new one — or already correct.

​
The profiles

The Cloudron profile is only offered on an instance running Cloudron.
Choose A website and email only if a mail server actually runs on this VPS. Pointing MX at a server that answers no mail stops your email from arriving, and the preview is where you see that coming: your current MX appears as a replacement, with its present value.

​
Reverse DNS

The email profile also sets the reverse DNS of the instance’s IP to its mail hostname. This is the one record a registrar cannot set for you — the address belongs to us — and mail servers check it before accepting your messages. See Reverse DNS.

​
When the IP changes

A reinstall or a migration can change the instance’s primary address. The domains pointing at it follow automatically: their A and AAAA records are rewritten to the new address, without you doing anything.

​
Detaching

Detaching a domain removes the link, and leaves the records in the zone. Removing them would take the site down at the moment you unlink it. Edit or delete them from the DNS zone when you want them gone.

​
A domain hosted elsewhere

The tab only offers domains whose zone we host, because it can only write into a zone it controls. For a domain kept at another provider, create the records yourself at that provider: Or transfer the domain here and the tab will offer it.

​
Propagation

A DNS change takes from a few minutes to a few hours to spread. Until then some networks still answer with the old address, which is expected.
