Host IDs/ MAC Address for Windows

If you are on an Windows workstation, you can obtain the Host ID by issuing the following command at a DOS command prompt like so:

C:\> ipconfig -all
(The C refers to your main directory. If you are on a network, another letter may indicate your main directory. Just enter ipconfig -all after the :\>)

and look for the Physical Address in the Ethernet Adapter section of the information returned (your information may vary):
