DESCRIPTION
The hostid command prints the identifier of the current host in hexadecimal.
This numeric value is expected to be unique across all hosts and is commonly
set to the host's Internet address. The superuser can set the hostid by giving
a hexadecimal argument or the hostname. This is usually done in a startup
script, for example, "/etc/rc." If the host is on two networks, set the hostid
to one of the ID addresses.
EXAMPLES
The hostid command returns the network address of the current host as a 32-bit
hexadecimal number.
$ /etc/hostid
0x491464c0
