Get Specific MAC Address

My VS2015 VB app is reading the MAC address of the users computer. This has worked well except some users are using laptops with docking stations that assign their own MAC address. The code I am using returns the first one it finds, can a specific one be searched for?
Dim mc As New ManagementClass(New ManagementPath("Win32_Processor"), New ObjectGetOptions(New ManagementNamedValueCollection()))
Dim moc As ManagementObjectCollection = mc.GetInstances()
mc.Path = New ManagementPath("Win32_NetworkAdapterConfiguration")
moc = mc.GetInstances()
Dim sMac As String = String.Empty
For Each mo As ManagementObject In moc
If (mo.GetPropertyValue("IPEnabled") = True) Then
If (sMac = String.Empty) Then
sMac = mo.GetPropertyValue("MacAddress").ToString()
End If
End If
Next

Have you tried to output the ServiceName to determine any difference between the laptop and dockstation (mo.GetPropertyValue("ServiceName"))?

I tried capturing the relevant services, was not able to determine the difference between a laptop and docking station without knowing more about each device.

This method is using System.Net.NetworkInformation.NetworkInterface instead of directly querying the WMI interface.
It returns informations on all the current Network Interfaces, except the Loopback interface, where the Operational Status is UP. This usually filters the Teredo and ISATAP interfaces and, of course, all the Network Interfaces that are not currently active.
The NetworkInterfaceType could also be used to filter other specific interface type, the NetworkInterfaceType.Wireless80211 for example.
I'm proposing this variant because it's simpler to modify/expand when required.
Each instance of the NetInterfaceMac class povides:
- The Interface human-friendly description
- The IPV4 addresses of the Interface
- The MAC address if string format (
"BF:D1:E8:8C:2B:A4") - The MAC address bytes
Public Class NetInterfaceMac
Public Property InterfaceDescription() As String
Public Property IPAddress() As IPAddress
Public Property MacAddress() As String
Public Property MacAddressBytes() As Byte()
End Class
Public Shared Function GetNetworkMACAddresses() As List(Of NetInterfaceMac)
Dim Macs As New List(Of NetInterfaceMac)()
Dim NetInterfaces As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
Macs.AddRange(NetInterfaces.Where(
Function(ni) ni.NetworkInterfaceType <> NetworkInterfaceType.Loopback AndAlso
ni.OperationalStatus = OperationalStatus.Up).
Select(Function(ni) New NetInterfaceMac() With {
.IPAddress = ni.GetIPProperties().UnicastAddresses?.
Where(Function(ip) ip.IsDnsEligible = True)?.Select(Function(ip) ip.Address).ToArray(),
.InterfaceDescription = ni.Description,
.MacAddress = ni.GetPhysicalAddress().GetAddressBytes().
Select(Function(b) b.ToString("X")).Aggregate(Function(s1, s2) s2 + ":" + s1),
.MacAddressBytes = ni.GetPhysicalAddress().GetAddressBytes()
}))
Return Macs
End Function
Sample call:
Dim Macs As List(Of NetInterfaceMac) = GetNetworkMACAddresses()
