    Configuring hosts

    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:
    1. Go to Global Load Balance > FQDN Settings.
    2. Click the Host tab.
    3. Click Create New to display the configuration editor.
    4. Complete the configuration as described in Host configuration.
    5. Save the configuration.

    Host configuration
    Settings Guidelines

    Name

    Configuration name. Valid characters are A-Z, a-z, 0-9, _, and -. No spaces.

    Note: After you initially save the configuration, you cannot edit the name.

    Host Name

    The hostname part of the FQDN, such as www.

    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: example.com.

    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
    • Weight—If selected, virtual server pool will be responded by weight.
    • DNS Query Origin—If selected, virtual server pool with the same topology information as the local DNS address will be responded.
    • Global Availability—If selected, virtual servers will be responded by their global availability: the first virtual server in queue will always be responded if it is globally available, and the next virtual server in queue will be responded if the preceding virtual server is unavailable.

    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.
