## Summary {#summary}

In this use case, the user assigns dns_name and dns_domain attributes to a floating IP when it is created. The floating IP data becomes visible in the external DNS service as soon as it is created. The floating IP can be associated with a port on creation or later on. The following example shows a user booting an instance and then creating a floating IP associated to the port allocated for the instance
