Configuring Domain Name Files

The host name data base file, (

HOSTS.NET.SYS

), associates internet

addresses with official host names and aliases. This allows a user to
refer to a host by a symbolic name instead of an internet address.

When you have configured the name server, this file serves only as a
backup when the server is not running. In this circumstance, it is a
common practice that

HOSTS.NET.SYS

 contains a few addresses of

machines on the local network.

To create the hosts file, perform the following steps:

Step 1. Copy the sample file,

HOSTSAMP.NET.SYS

, to

HOSTS.NET.SYS

.

Step 2. Modify

HOSTS.NET.SYS

 using any ASCII editor so that it contains

information about the nodes on your network.

To modify an already existing

HOSTS.NET.SYS

 file, simply use your

editor to update and save the existing file.

Enter a single line for each host, including the following information:

[internet address] [local host name] [aliases]

A line cannot start with a space. Items are separated by any number of
blanks and/or tab characters. A pound sign (

#

) indicates the beginning

of a comment.

Network addresses are specified in dot format, with leading zeros
omitted and a period between each grouping. (See example addresses in
Figure 12-2.)

Host names can contain any printable character other than a white
space, newline, or comment character.

It is very important that you omit the leading zeros in the network
addresses. If you enter the leading zeros here, the domain name
resolver will interpret the numbers as octal numbers.
