    Is this "number" the MAC address? Or the locally administered network
    address? Or something totally different?

    What is this number called?

    No offense but please respond with reasonable answers & keep out the
    jokes, off-topic nonsense, taunts, insults, and trivializations. I am
    really interested in this.

  5. The basis for your question, i.e. "a unique identifying code number"
    does not narrow it down to a single answer. Perhaps you mean the serial
    number on the bottom of most laptops, perhaps you mean the MAC address
    of the networking device in the laptop. Until you are more specific, it
    would be very hard to give a definitive answer. If you mean the MAC
    address, it's an twelve character alphanumeric identifier assigned to
    networking devices such as wireless cards and ethernet cards. They are
    supposed to be unique, but accidents can happen. And if you have two or
    more networking devices then you have two or more MAC addresses in the
    same machine.

    If you'd be so kind as to use Google and type in "define MAC address"
    there's a lot more information available than I'd care to retype.

    Even though your quote is lacking sufficient detail to place it in context
    the most likely 'number' your quote refers to is what is know as a TCP/IP
    address. The TCP/IP networking protocol is the protocol used on the Internet
    and nowdays the majority of Local Area Networks.

    TCP/IP networking works by assigning a unique number to each computer or
    device connected to the network.
    This number can be permanently assigned (static address) or lent temporarly
    from a pool of address's (dynamic) address. The numbers are made up of four
    octets separated by a dot. The numbers range from to, for example is the Internet address for
    Therefore for your Laptop to connect to a TCP/IP network you must either
    assign a TCP/IP address to it or have one granted to it by some other

    Depending on your method of connection to the Internet either your Laptop
    (for dial up) or your Router (for broadband) will be assigned a TCP/IP
    number from your ISP's pool of numbers that it has bought the rights to.
    You could think of this TCP/IP address as akin to a house number/street
    address for your regular snail mail.

    There are many reference documents available on the Web that will give you
    chapter and verse on the tiniest detail of TCP/IP. For example
    I can only encourage you to read them up.

  7. Uhm. Finally, this was the 3rd thread from you without any
    clarification "which" unique number you are talking about and how the
    number would be transmitted. There is the MAC address , the CPUID and the
    serial number of your(?) laptop. The former two numbers are captured by
    programs like windows activation/validation, and munged to a code that's
    transferred regularly. Some other programs may as well grab the IDs without
    munging them, and send them elsewhere.
    In addition, the serial number of most modern laptops as printed on the
    label, is also imprinted into the bios chip - some management software (DMI
    or other) can get that one as well.
    If you are really paranoid, don't use a computer or at least do not connect
    it to the internet, or only use public computers at internet cafes where
    you don't need to prove identity.

    The distinctive identification is probably the MAC address. However,
    it has no meaning unless it can be linked to other information. IOW,
    it is just a number. Any local administrator can use the MAC address
    to assign an identification to the laptop but the relevance is between
    the laptop and the interested network. In this instance, the laptop
    might be known by its assigned domain name, e.g., Radium226.

    From this point, where else do you want to take this discussion?
