HostNone

`HostNone` is a setting used in programming and software configurations, particularly in environments like Docker or container orchestration tools, to specify that a service or container should not be connected to any specific host interface. Essentially, it indicates that the service will run without binding to a particular network interface, making it inaccessible directly from network sources outside the system. This can be useful for security or isolation purposes, ensuring the service only communicates internally or under certain conditions, reducing exposure and potential vulnerabilities associated with network access.
