After you deploy the vCenter Server Appliance, you can edit the DNS settings and specify which DNS server to use. You can also edit the IP address settings of the vCenter Server Appliance, specify whether to use IPv4 and IPv6 or only IPv6, and how the appliance obtains the IP address.
Before you begin
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, because the system name is used as a primary network identifier.
Verify that the user name you use to log in to the vCenter Server instance in the vCenter Server Appliance is a member of the SystemConfiguration.Administrators group in vCenter Single Sign-On.
