I'm using Ubuntu 16.04. I recently started learning DevOps and got a bit crazy with my 'etc/hosts' and 'etc/hostname' files. In my frantic attempt to spin up a couple of servers from my local machine I lost track of the default settings, and was just curious to know what they are/were.

As I recall 'etc/hosts' and 'etc/hostname' had only one entry, which was the username of my local machine. However I'm not entirely sure.

By any chance does anyone know what the default settings are with a fresh install? Thanks


They are based on what you specified as the hostname when you installed: in my below examples "myhostname" is the name you chose. The defaults look a bit like this:



/etc/hosts myhostname localhost

# 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
  • and myhostname is in /etc/hostname. – josifoski Sep 26 '18 at 10:58
  • That's what's there is it not? – thomasrutter Sep 27 '18 at 4:54
