Setting the Hostname is not required. You can just use localhost as the hostname to access Ambience, if you are accessing Ambience from the same system as where Ambience is installed.

However, if you want the Ambience server to be available to other machines across the network, you cannot use the localhost default, and need to use the fully qualified domain name of the server system to access it. To facilitate access, ensure that the server's Fully Qualified Domain Name (hostname) is set to the server's IP address in /etc/hosts (on Unix/Linux/Mac), or in \windows\system32\drivers\etc\hosts (on Windows).

To determine the system's hostname, open a command prompt or terminal, and type the command:

hostname

Open the hosts file and associate the hostname with the system's IP address. For example,

192.168.1.6 ambience-server.example.com

Next, contact your IT department and ask them to set up the appropriate DNS record for the Ambience server.
