I think they changed the config that in the case of DHCP it assumes the domain supplied.

If you are behind any sort of gateway, especially using NAT you want to use the internal IP address, with some exceptions, and then using nat forward the information. The rest is kind of optional and will vary based on what you need. I do know that if you have Nate forwarding and your access via the same hostname inside and outside it can get strange if you have 2 different IP addresses (IE internal and external).

Hi,

I recently installed Ubuntu 20.04 and it did not ask for my domain. I
am building a PHP web hosting server for learning.

Prior to this when installing Linux it always asked me for the domain
the machine was going to be in. Maybe I missed something.

When I issued the command "hostname" it returned the host name. When I
issued the command "hostname -f" it only returned the hostname.

To fix this I added this line to /etc/hosts "255.255.255.255
hostname.Domain.tld hostname".

255.255.255.255 represents my public IP.

Questions

1) Did I miss something on the install?
2) I am running BIND so is the line I added necessary to "fix" the FQDN?
3) Is there another or better way?
4) Since my webserver is on a private IP using port forwarding, should I
use my private IP in /etc/hosts instead of my public IP?

Thanks!!
