Change Hostname
In this article, you'll learn how to change the hostname for Plesk servers with Managed or Unmanaged support levels. If the server is to be used for sending emails, make sure that all required steps are completed in full; otherwise, outgoing emails will be rejected immediately if, for example, the technical hostname does not match the RDNS entry.
Preparation
To change the hostname in Plesk, you must first prepare the corresponding DNS records. To do this, navigate to the desired DNS zone in the Customer Center and create the appropriate DNS records for the IPv4 and IPv6 addresses.
Example:
| RR Type | Host | Value | TTL |
|---|---|---|---|
| A | web | IPv4 Address | 3600 |
| AAAA | web | IPv6 Address | 3600 |
You can view the server’s current IPv4 and IPv6 addresses in the Customer Center under the Network tab.
Changing the RDNS Hostname (Reverse DNS)
Access the server via our Customer Center and navigate to the Network tab.
In the Available IP Addresses section, you can edit the RDNS entry for the respective IP addresses. Please make sure to update the RDNS hostname for both the IPv4 and IPv6 addresses.
Changes in Plesk
To do this, navigate to the desired server in the Customer Center and select Plesk Control Panel. Then navigate to the menu item Tools & Settings → Server Settings.
Enter the new hostname you want in the Full Hostname field.
SSL Certificates
Next, navigate to the menu item Tools & Settings → SSL Certificates and click the Let’s Encrypt button to issue a new certificate for the server.
After the certificate has been successfully issued, you may need to completely reload the Plesk Control Panel for the certificate changes to take effect.
Control Panel (Optional)
If you use the Plesk Single Sign-On feature in our Customer Center, you’ll also need to update the hostname there. In the Customer Center, navigate to the Control Panels tab and edit the hostname to the new one.
