what should be in the /etc/hosts file if I have dynamic ip?

Dear friends,

In the /etc/hosts file, we usually put the localhost IP with localhost.localdomain, and if we have the IP for the ethernet interface we can state the IP with the domain.

But what if I only have a dynamic ip that changes every network restart or reboot, what should stated in the /etc/hosts file?

if I have fixed IP i can do this in /etc/hosts:
127.0.0.1 localhost.localdomain
192.168.100.100 saturn.cbc.com

if I do not have fixed ip, what can i put as ip in the 2nd line?

please help...thanks for taking time reading my thread, thanks.

regards
yong

Don't put anything as the second line. Do something like:

Code:

arcruea@zeus ~ $ cat /etc/hosts
# /etc/hosts
#
# This file describes a number of hostname-to-address
# mappings for the TCP/IP subsystem.  It is mostly
# used at boot time, when no name servers are running.
# On small systems, this file can be used instead of a
# "named" name server.  Just add the names, addresses
# and any aliases to this file...
#

127.0.0.1       zeus.cruea.net zeus localhost
arcruea@zeus ~ $
