ip _pool _silo _update
When a user asks for an IP (e.g., at instance create time) without specifying a pool, the IP comes from the default pool if a default is configured. When a pool is made the default for a silo, any existing default will remain linked to the silo, but will no longer be the default.
Path Parameters
Request Body
When a pool is the default for a silo, floating IPs and instance ephemeral IPs will come from that pool when no other pool is specified. There can be at most one default for a given silo, so when a pool is made default, an existing default will remain linked but will no longer be the default.
Responses
