Hey Dennisotieno46,

An easy way to understand the differences between these different naming devices is to think about it like this.

A Server Name and a Droplet Name are all user definable, meaning you can truly set these as whatever you would like and it for the most part will just help you remember server a from server b.

Whereas hostnames and domain names have to do with how the public can access your server.

Domain Names are registered with a separate domain registrar and are what you generally see in your browser address bar. For example, if you own the domain name dennis.com you would be able to type that in and the browser would point to your server.

So a hostname is a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication such as the World Wide Web, email or Usenet.

So if I have droplet and I give it the hostname onix.dennis.com if I own the domain name dennis.com I can edit the DNS to directly point to the droplet.

To sum this all up.

Server Name and Droplet Name are for your own purposes to help you remember server A from server B

and

Hostname and Domain name directly have an impact on how people are going to either access your site or your service that you are providing.

and

Hostname and Domain Name are directly set to equal to an ip address for the public which is also automatically assigned to your droplet.

Hope this helped a little and if you have any questions feel free to ask away.

I would suggest you read up on how domains and DNS works so you can generally have a good understanding of how the internet works.

Hope this helps and welcome to Digital Ocean,
Mark

    Hi Mark,

    when I set up my first droplet and followed some tutorial, I gave it only a name without ".com" or anything. I don't use DNS at DigitalOcean, I am using Cloudflare for that and everything seems to work fine.

    But are there any disadvantages when the droplets name is not a "fully qualified hostname" but just a simple word? For example, does the server send out any status mails or what so ever to a mail address ending with the hostname? Those mails would never be delivered to me.

    And if that's the case, what is the proper way to change the hostname?

    Thank you!

      I'm having the same problem, in case of using cloudflare for DNS how to do that, any tutorial available?

        Hey, I never changed the host name and everything still works fine. Cloudflare.com setup is easy, just sign up and follow their instructions. They'll give you nameservers to point your domain to and then you can manage the DNS inside their panel.
