Hosts file format
A hosts file is a list of IP addresses and the names (host names and domain
names) that are associated with them. The hosts file can be stored anywhere
on your server’s hard drive, but it is usually stored in the Preferences folder
in your active System Folder. To make a particular hosts file active, locate it
through the Select Hosts file button in the TCP/IP control panel.
The information in the hosts file consists of a series of records whose fields
must be in the following format:
name data ; comment
The name field can be an alias or a fully qualified domain name (that is, it
contains at least one dot). For example, “apple.com” is a fully qualified
domain name; “apple” is not.
The data field in a hosts file record includes the following subfields, each
separated by one or more space characters.
WARNING If you do not change the IP address, you may
cause the same IP address to be used by two different
computers on the network, which causes network errors.
