     1  # IP Addresses
     2  
     3  An installer-provisioned vSphere installation requires two static IP addresses:
     4  
     5  * **API** - used to access the cluster API.
     6  * **Ingress** - used for cluster ingress traffic.
     7  
     8  A virtual IP address for each of these should be specified in the [install configuration](install.md#create-configuration).
     9  
    10  # DNS Records
    11  
    12  DNS records must be created for the two IP addresses in whichever DNS server is appropriate for the environment.
    13  The records should have the following values:
    14  
    15  | Name                                  | Value       |
    16  | -                                     |  -          |
    17  | `api.<cluster-name>.<base-domain>`    | API VIP     |
    18  | `*.apps.<cluster-name>.<base-domain>` | Ingress VIP |
    19  
    20  Note that `cluster-name` and `base-domain` are variables custom to an installation and
    21  must correspond to the values specified in the [install configuration](install.md#create-configuration).
