Basic TCP/IP configuration parameters

Host name

The local host name for a system should be unique on your network. It can consist of lowercase letters and numbers, must begin with a letter, and should be no longer than 63 characters. mail and other programs use the host name to identify the correct data destination. Example valid machine names are scosysv, tcpdev, and account1.

Each network interface can be configured with a different host name. The host name and associated IP address for the interface are added to the /etc/hosts file.

NOTE: You can also change entries in /etc/hosts using the Client Manager.

You cannot change the system name using the Network Configuration Manager. You must use the uname(1) command to do this.
