Configuring DNS
The following DNS records are required for VMware with the appropriate domain name mentioned in TICG. Ensure that the forward lookup and reverse lookup are working before starting the installation. Some sample hostnames are listed in the following table. Ensure the hostnames and IP addresses match the entries mentioned in TICG by the user.
| Component | Record | Description |
|---|---|---|
