Tru64's DESCRIPTION:
The hostid command displays the 32-bit identifier of the host as a
hexadecimal number in host standard byte order. The identifier must be
unique across all hosts and is commonly set to the Internet address of the
specified host. The superuser can set the host ID by specifying a
hostname, internet_address, or hexadecimal_number argument. The identifier
is stored in network standard byte order.
It appears it is basically the IP address by default, unless the
sysadmin decides to change it.
