Hosts file change syntax

I am attempting to migrate a website to a ubuntu server but would like to test it first

On windows I have changed my host file to point to the server, so the browser is opening the "new" site. In my terminal , in Ubuntu I have changed the following

127.0.1.1 example example 127.0.0.1 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 

to

127.0.1.1 example example 127.0.0.1 localhost 104.236.247.139 104.236.247.139 example.com # 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 

Can I confirm that this is correct? I seem to be running into issues with finding http image urls etc, and before trying to debug I want to make the hosts file is correctly set.

Thanks

Your /etc/hosts file should look like this:

127.0.1.1 example 127.0.0.1 localhost 104.236.247.139 example.com # 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 

For 127.0.1.1 you have put two same hostnames whereas just one will do. For the IP 104.236.247.139 you have used two different lines to express hostname and alias but you should put the hostname and aliases all in a single line separated by whitespaces, for example:

<IP_Address> <hostname> <alias_1> <alias_2> <alias_3> 104.236.247.139 example.com foo.com bar.com
