Qwarq Virtual Ethernet Adapter - dynamic MAC

    Question

  • I've run across a situation not seen before.  A Dell Inspiron Duo running Windows 7 that has a network adapter called "Qwarq Virtual Ethernet Adapter" that appears to create a new MAC everytime the machine boots.  Below is a dump of the management object Win32_NetworkAdapter for it:

    Path=\\WIN7TOUCH\ROOT\cimv2:Win32_NetworkAdapter.DeviceID="7"
    AdapterType=Ethernet 802.3
    AdapterTypeId=0
    AutoSense=nothing
    Availability=3
    Caption=[00000007] Qwarq Virtual Ethernet Adapter
    ConfigManagerErrorCode=0
    ConfigManagerUserConfig=False
    CreationClassName=Win32_NetworkAdapter
    Description=Qwarq Virtual Ethernet Adapter
    DeviceID=7
    ErrorCleared=nothing
    ErrorDescription=nothing
    GUID={1706D6B8-E049-4DCB-9046-64C8FCB53C33}
    Index=7
    InstallDate=nothing
    Installed=True
    InterfaceIndex=10
    LastErrorCode=nothing
    MACAddress=0A:00:7B:2C:6F:2F
    Manufacturer=ConnectSoft, Inc.
    MaxNumberControlled=0
    MaxSpeed=nothing
    Name=Qwarq Virtual Ethernet Adapter
    NetConnectionID=Local Area Connection
    NetConnectionStatus=7
    NetEnabled=False
    NetworkAddresses=nothing
    PermanentAddress=nothing
    PhysicalAdapter=True
    PNPDeviceID=ROOT\ROOT&QWARQNET\0000
    PowerManagementCapabilities=nothing
    PowerManagementSupported=False
    ProductName=Qwarq Virtual Ethernet Adapter
    ServiceName=QWARQNet
    Speed=9223372036854775807
    Status=nothing
    StatusInfo=nothing
    SystemCreationClassName=Win32_ComputerSystem
    SystemName=WIN7TOUCH
    TimeOfLastReset=20110811105205.125599-240

     

    I can't seem to find any information on this adapter nor do I see a manufacturer block for the 0A-00-?? addresses it seems to generate.

    This is apparently the official web site for Qwarq  http://www.qwarq.com

     

    The changing MAC is causing me consternation.  Has anyone run across an adapter like this?  More importantly, is this type of dynamic MAC behavior something that will be increasingly seen in the future?

  • Hi,

     

    This adapter should be created by Qwarq. Please understand this isn’t published by Microsoft Corporation, we don’t have much information about it.

     

    I suggest that you may contact Qwarq to get more information.

  • I'm not so much fixated on Qwarq so much as the general increase of dynamic MACs.  History clouded my judgement in thinking that each network interface would have a fixed (burned in) MAC.  This was incorrect.  http://en.wikipedia.org/wiki/MAC_address

    Most of the hardware and networking that I'm exposed to are fixed MACs.  Having run across the dynamic MAC in a piece of software that could be in wide spread use made me wonder what other people are seeing?

    Additionally finding that 0A-00-?? is not listed in http://standards.ieee.org/regauth/oui/oui.txt made me think there might be more to learn here.
