Explanation:

The object of the container network model (CNM) that contains the configuration files of a container's network stack, such as routing table, container's interfaces, and DNS settings, is the Sandbox. A Sandbox is a logical entity that encapsulates the network configuration and state of a container. A Sandbox can contain one or more endpoints from different networks, and provides isolation and security for the container's network stack. A Sandbox can be implemented using various technologies, such as Linux network namespaces, FreeBSD jails, or Windows compartments. A Sandbox allows the container to have its own view and control of the network resources, such as interfaces, addresses, routes, and DNS settings123.
