/etc/hosts
Each node has a one line entry in the /etc/hosts file. Each entry in the file takes the
following form:
Syntax
IP_address host_name [ alias ]...
Parameters
IP_address The IP address that uniquely identifies the node. IP_address must be in
internet “dot” notation. Refer to Chapter 7, Network Addressing, for more
information on IP addresses.
host_name Name of the node. Host names can contain any printable character except
spaces, newline, or the comment character (#). Naming Convention: the first
nine characters should be unique for each network host.
alias Common name or names for the node. An alias is a substitute for
host_name . Alias names are optional. Naming Convention: the first nine
characters should be unique for each network host.
/etc/hosts Format
When creating the /etc/hosts file, follow these rules:
• Lines cannot start with a blank or tab character.
• Fields can have any number of blanks or tab characters separating them.
