A public IP address can be created as a separate resource or can be unassigned from another resource and exist on its own. Such an IP address can then be assigned to a new or another resource. If the resource is no longer in use or migrated, we can still use the same public IP address. In this case, the public endpoint that's used to access a service may stay unchanged. This can be useful when a publicly available application or service is migrated or upgraded as we can keep using the same endpoint and end users don't need to be aware of any change.
