After you deploy the vCenter Server Appliance, you can edit the DNS settings and specify which DNS server to use. You can edit the IP address settings of the vCenter Server Appliance. You can also specify whether to use IPv4 and IPv6 or only IPv6, and how the appliance obtains the IP address.
You can edit these settings by using the vSphere Web Client.
Prerequisites
-
To change the IP address of the appliance, verify that the system name of the appliance is an FQDN. If, during the deployment of the appliance, you set an IP address as a system name, you cannot change the IP address after the deployment. The system name is always used as a primary network identifier.
-
Verify that the user who logs in to the vCenter Server instance in the vCenter Server Appliance is a member of the SystemConfiguration.Administrators group in vCenter Single Sign-On.
