linux:~ # cat /etc/hosts

#

# 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.

# Syntax:

#

# IP-Address  Full-Qualified-Hostname  Short-Hostname

#

 

127.0.0.1 feb01.cn.ibm.com  localhost

 

# special IPv6 addresses

::1             localhost ipv6-localhost ipv6-loopback

 

fe00::0         ipv6-localnet

 

ff00::0         ipv6-mcastprefix

ff02::1         ipv6-allnodes

ff02::2         ipv6-allrouters

ff02::3         ipv6-allhosts
