Configuring hosts
Host settings are used to form the zone configuration and resource records in the generated DNS zone used for global load balancing.
Host configuration and the generated DNS zone shows how the host settings are mapped to zone settings and resource records. Domain and hostname are used in both the configuration and the generated configuration name. The IP address and weight are derived from the virtual server pool.
Host configuration and the generated DNS zone
Before you begin:
- You must have created the global virtual server pools you want to use.
- You must have Read-Write permission for Global Load Balance settings.
After you have created a host configuration object, it can be used to form the zone and resource records in the generated DNS zone configuration.
To configure a host:
- Go to Global Load Balance > FQDN.
- Click the Host tab.
- Click Create New to display the configuration editor.
- Complete the configuration as described in Host configuration.
- Save the configuration.
| Settings | Guidelines |
|---|---|
|
Name |
Configuration name. Valid characters are Note: After you initially save the configuration, you cannot edit the name. |
|
Host Name |
The hostname part of the FQDN, such as Note: You can specify the @ symbol to denote the zone root. The value substituted for @ is the preceding $ORIGIN directive. |
|
Domain Name |
The domain name must end with a period. For example: |
|
DNS Policy |
Select the DNS policy you want the host to use. |
|
Respond Single Record |
Enable/disable an option to send a single record in response to a query. Disabled by default. By default, the response is an ordered list of records. |
|
Persistence |
Enable/disable the persistence table. Disabled by default. If you enable persistence, the client source address is recorded in the persistence table, and subsequent requests from the same network or the same host or domain are sent an answer with the virtual servers listed in the same order (unless a server becomes unavailable and is therefore omitted from the answer). |

Virtual Server Pool Selection Method |
|
|
Default Feedback IPv4 |
Specify an IP address to return in the DNS answer if no virtual servers are available. |
|
Default Feedback IPv6 |
Specify an IPv6 address to return in the DNS answer if no virtual servers are available. |
| Virtual Server Pool | |
| Name |
Enter the mkey. |
| Virtual Server Pool |
Select a virtual server pool from the list, or create a new one. |
| Weight |
Assign a weight. Valid values range from 1 to 255. |
| Topology |
Select a topology from the list, or create a new one. |
| ISP |
Select an ISP from the list or create a new one. |
