I need to get the host name currently running the application. Any idea?

In C, you may use the gethostname function. #include <unistd. h> int gethostname(char *name, size_t namelen); The gethostname() function shall return the standard host name for the current machine.
Find out your hostname in Windows The easiest way to display the hostname of a Windows computer is to open the command prompt, enter the following code and press “Enter”. The host name is displayed in the line labeled “Host Name”. The hostname is displayed after entering the command “ipconfiq /all”.
On your Windows PC, follow these steps to find your FQDN: Launch the Control Panel by searching for "Control Panel" in the Start Menu, or by typing Win+R and typing "control.exe" in the Run menu. On the System Information screen, you will see both the hostname and FQDN of your machine.
The /usr/bin/hostname command displays the name of the current host system. Only users with root user authority can set the host name. The mkdev command and the chdev commands also set the host name permanently. Use the mkdev command when you are defining the TCP/IP instance for the first time.
Something to bear in mind is that System.Environment.MachineName; and System.Windows.Forms.SystemInformation.ComputerName; will give you the NETBIOS name of the machine (restricted to 15 characters).
If you want the full TCP/IP based host name you can use Dns.GetHostName():
string hostName = System.Net.Dns.GetHostName(); Or you can use:
System.Environment.GetEnvironmentVariable("COMPUTERNAME"); Which will return the full computer name set during installation.
