# ElasticAddress

URL: https://developers.cloud66.com/v3/models/elastic-address/

Elastic addresses (also known as failover groups) provide high availability by allowing IP addresses to be moved between primary and secondary stacks during failover operations. They enable zero-downtime maintenance and automatic disaster recovery.

<Model>
    <ModelProperty name="uid" type="string">
        The unique identifier of the elastic address.
    </ModelProperty>
    <ModelProperty name="address" type="string">
        The elastic IP address that can be switched between stacks.
    </ModelProperty>
    <ModelProperty name="current_stack" type="string">
        Which stack currently owns the IP address ("primary" or "secondary").
    </ModelProperty>
    <ModelProperty name="primary_stack_uid" type="string|null">
        The unique identifier of the primary stack (null if not configured).
    </ModelProperty>
    <ModelProperty name="primary_stack_name" type="string|null">
        The display name of the primary stack (null if not configured).
    </ModelProperty>
    <ModelProperty name="secondary_stack_uid" type="string|null">
        The unique identifier of the secondary/backup stack (null if not configured).
    </ModelProperty>
    <ModelProperty name="secondary_stack_name" type="string|null">
        The display name of the secondary/backup stack (null if not configured).
    </ModelProperty>
    <ModelProperty name="busy_toggling" type="boolean">
        Whether a failover operation is currently in progress.
    </ModelProperty>
    <ModelProperty name="readonly" type="boolean">
        Whether the current user can edit this elastic address.
    </ModelProperty>
    <ModelProperty name="created_at" type="string">
        The ISO 8601 timestamp when the elastic address was created.
    </ModelProperty>
    <ModelProperty name="updated_at" type="string">
        The ISO 8601 timestamp when the elastic address was last updated.
    </ModelProperty>
</Model>
