Please assist with hosts setup

Hi all

I have an Ubuntu droplet.

Let’s say my domain name is mywebsite.com

My current etc/hosts file looks like this:

# Your system has configured 'manage_etc_hosts' as True.
# As a result, if you wish for changes to this file to persist
# then you will need to either
# a.) make changes to the master file in /etc/cloud/templates/hosts.tmpl
# b.) change or remove the value of 'manage_etc_hosts' in
#     /etc/cloud/cloud.cfg or cloud-config from user-data
127.0.1.1 Mywebsite Mywebsite
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

Now according to https://github.com/DigitalOcean-User-Projects/Articles-and-Tutorials/blob/master/set_hostname_fqdn_on_ubuntu_centos.md#setting-the-fully-qualified-domain-name-fqdn

It should look like this:

127.0.0.1 localhost.localdomain localhost 127.0.1.1 hostname.yourdomain.tld hostname YourIP hostname.yourdomain.tld hostname

Can you translate that using my domain name, assuming my IP is 123.123.123.1

Am I missing something?

I am using DO DNS servers.

Thanks

Jacques
