What is the proper way to add an entry to /etc/hosts.
Code
cat /etc/hosts
#Do not edit this file, your changes will get lost.
127.0.0.1 localhost.localdomain localhost
127.0.1.1 omvad3.example.com omvad3
# The following lines are desirable for IPv6 capable hosts.
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
