That's called IP spoofing, if you use IP of another host.
it's often used by hacker. :)

hostid: the unique id of the machine. I don't know how the number
is generated. In unix, type "hostid" command.
NIC #: NIC's uniqe number. Normally called MAC address (physical address
of NIC, etc). The number is allocated for each manufacture of
NIC, so it's guaranteed unique.
fake NIC# or IP: it's spoofing. In unix, use "libnet" you could
easily construct arbitrary packet to forge MAC/IP address.
