The Internet is a world-wide network of computers. The computers are divided into domains and sub-domains. Each machine has a name and an address which is unique across the Internet. To check the name of the machine you are logged on use the command hostname. The names of some of the departmental server machines in the labs are:
| Hostname | Fully Qualified Domain Name | Internet Address |
| onyx | onyx.boisestate.edu | 132.178.226.68 |
| cs | cs.boisestate.edu | 132.178.226.55 |
The suffix boisestate.edu represents the sub-domain comprised of all the machines on campus. To find the Internet address of a machine, use the command host <hostname>. Here are some examples.
