full_host_list — Resolve the full host names of all servers to which the given server refers.
This command looks up the list of hosts the provided host will resolve to. This default to the result of a lookup on the result of `hostname`; that is, if no host is provided, the command will use the host it is being run on.
Each host will have its name fully resolved. In the case of a lookup that resolves only a single server (such as in the default case), this will just give a full standardized name for that particular host. If a round-robin server such as linux.student.cs is used, this will give a list of all hosts that server potentially can select.
