Host as server configuration

If the host machine will have a specific function like serve as a gateway, file server, or name server, you must perform the necessary configuration tasks after the basic configuration is complete.

For example, if your network is organized hierarchically and you want to use the Domain Name protocol to resolve names into Internet addresses, you will need to configure at least one name server to provide this function for your network.

Remember, a server host does not have to be a dedicated machine, it can be used for other things as well. If the name server function for your network is fairly small, the machine might also be used as a workstation or as a file server for your network.
