DNS Requirements for the vCenter Server Appliance and
Platform Services Controller Appliance
When you deploy the new vCenter Server Appliance or Platform Services Controller appliance, in the
temporary network settings, you can assign a static IP address and an FQDN that is resolvable by a DNS
server. After the upgrade, the appliance frees this static IP address and assumes the network settings of
the old appliance.
When you deploy the vCenter Server Appliance or Platform Services Controller appliance with a static IP
address, you ensure that in case of system restart, the IP address of the appliance remains the same.
Before you deploy the vCenter Server Appliance or Platform Services Controller appliance with a static IP
address, you must verify that this IP address has a valid internal domain name system (DNS) registration.
When you deploy the vCenter Server Appliance, the installation of the Web server component that
supports the vSphere Web Client fails if the installer cannot look up the fully qualified domain name
(FQDN) for the appliance from its IP address. Reverse lookup is implemented using PTR records.
If you plan to use an FQDN for the appliance system name, you must verify that the FQDN is resolvable
by a DNS server.
You can use the nslookup command to verify that the DNS reverse lookup service returns an FQDN
when queried with the IP address and to verify that the FQDN is resolvable.
nslookup -nosearch -nodefname FQDN_or_IP_address
If you use DHCP instead of a static IP address for the vCenter Server Appliance or
Platform Services Controller appliance, verify that the appliance name is updated in the domain name
service (DNS). If you can ping the appliance name, the name is updated in DNS.
Ensure that the ESXi host management interface has a valid DNS resolution from the vCenter Server and
all vSphere Web Client instances. Ensure that the vCenter Server has a valid DNS resolution from all
ESXi hosts and all vSphere Web Clients.
vSphere Web Client Software Requirements
Make sure that your browser supports the vSphere Web Client.
The vSphere Web Client 6.5 requires Adobe Flash Player v. 16 to 23. For best performance and security
fixes, use Adobe Flash Player 23.
VMware has tested and supports the following guest operating systems and browser versions for the
vSphere Web Client. For best performance, use Google Chrome.
