Using Your Own Domain (Custom Domain)

You can reach your hosted UniFi Network controller at your own domain name (for example unifi.example.com) instead of the pXXX.cloudunifi.com hostname we assign you. TLS certificates are issued automatically.

Adding a custom domain

In your domain registrar's DNS panel, add a CNAME record for the name you want to use, pointing at your assigned hostname (pXXX.cloudunifi.com, or xxxxxx.netconsole.cloud if your controller has been migrated to UniFi OS). Use a CNAME rather than an A record — if we ever move your controller, your domain keeps working.
Wait for DNS to propagate (usually minutes, up to 48 hours).
In the customer portal, open your service, go to the Custom Domain section, enter the domain and click Add Domain. The certificate is issued within a couple of minutes.

Plans P15–P50 include one custom domain; P75 and above can add several.

Changing your custom domain

Read this before removing or replacing a domain

Your controller tells every UniFi device which address to check in with — the inform host. If your inform host is your custom domain and you remove that domain, every access point, switch and gateway that has not yet picked up a new address is immediately disconnected and will show Unable to resolve or Adopting until the domain is added back. On a large deployment that can be hundreds of devices across many sites.

Because of this, the portal will not let you remove a domain that is currently your controller's inform host. It is marked with an Inform host badge in the Custom Domain section.

Change domains in this order:

Add the new domain first (see above) if you are switching to a different name. Wait for it to show as Active.
In UniFi Network, open Settings → System → Advanced and set Inform Host (the Override Inform Host option) to the domain you are keeping. Apply the change.
Wait until every site shows all devices connected. Devices pick up the new inform host on their next check-in — usually within a few minutes. Devices that are offline only update when they come back online, so if some sites have powered-down equipment, wait for them.
Return to the portal and remove the old domain. The badge will have moved to the new domain and the Remove button will be available.

If you skip a step the portal shows a message explaining what is still in use; nothing is changed until the order above is followed.

Only one domain on your plan?

If your plan allows a single custom domain you cannot add the new one first. Set Inform Host to your assigned CloudUniFi hostname (pXXX.cloudunifi.com / xxxxxx.netconsole.cloud) instead, wait for all devices to reconnect, remove the old domain, add the new one, and then point Inform Host at the new domain.

Removing a custom domain

Follow the same order as above: move the inform host away from the domain, wait for all devices to reconnect, then remove the domain in the portal. The assigned CloudUniFi hostname always stays available and cannot be removed.

Need help?

If you are unsure which address your devices are using, or you need a domain removed urgently, contact support through the web chat before making changes — we can check the live device state for you.
