Const Computer As String = "." ' Namespace to access the Win32_NetworkAdapterConfiguration class. ' ' Reference: ' ' ', Cactus Data ApS, Gustav Brock ' Public Function GetMacAddresses() As Variant() ' This computer. IP address (first if several) ' 4: String.
The NIC has been assigned a default IP gateway ' 3: String. ' ' The array has four dimensions: ' 0: Byte array. ' Retrieves from the local computer an array of the NICs having a MAC address. Thus, the first step is to retrieve the list of MAC addresses of the interface cards, and the function GetMacAddresses does that: Also, if the computer hosts virtual machines, at least one virtual network card exists in addition to the physical network cards. The reason is that a computer may have several other interfaces than the network card (NIC) that connects it to the LAN, be it wired or wireless. This is a typical task that should be simple but surprisingly is not. Note: Here we will deal with IPv4 MAC addresses only.
If that's what you are looking for, a good place to start is here: However, a guide to MAC addresses is outside the scope of this article. The MAC address is the unique identifier of every piece of hardware connected to a network.
