1. Hint

If you have no Ethernet adapter and no connection to the Internet you can mostly disregard this screen and just invent a name for your machine. Even the IP number is optional.

On the other hand, if you:

• have an Ethernet adapter,
• intend to do some networking with Linux with other UNIX/Linux machine on your LAN,
• know nothing about TCP/IP networking,
• and nobody around knows anything about TCP/IP networking,

then select the option "Install Isolated/simple network from scratch" under the menu item "Networking." You can then disregard this screen.
