Randomblue asked:
I need to get my NIC ID for a temporarily software license to be generated for me. How should I find my NIC ID?
I have found contradictory information on the web. Some suggested that I run getmac.exe
:
C:\Windows\System32>getmac.exe
Physical Address Transport Name
=================== ==========================================================
D4-BE-D9-1C-4F-C7 \Device\Tcpip_{7E28ABA4-55A5-4ECC-9B9A-8A440CDB9B95}
24-77-03-3E-B2-9C Media disconnected
7C-E9-D3-FE-40-41 Media disconnected
24-77-03-3E-B2-9D Media disconnected
From that, I assume my NIC ID is {7E28ABA4-55A5-4ECC-9B9A-8A440CDB9B95}
. But then others have suggested to go to Device Manager -> Network adapters -> [my NIC] -> Details
but I get many IDs in the same format as above, not just one:
My answer:
These sorts of software licenses generally tie themselves to the MAC address of an Ethernet adapter in the server on which they’re to be run. Which is annoying as hell when the NIC breaks and has to be replaced… So the NIC ID they’re asking for is almost certainly the MAC address.
An OUI search gives really interesting results for those MAC addresses:
24:77:03 Intel Corporate
7C:E9:D3 Hon Hai Precision Ind. Co.,Ltd.
D4:BE:D9 Dell Inc
Just what on earth do you have in that server?
Anyway, to figure it out for sure, run ipconfig /all
and scroll through the output until you find the entry matching your current IP address. A running example from my workstation:
Ethernet adapter Ethernet:

You can see here that the IPv4 address is 172.25.49.1
, the IPv6 address is 2001:db8:1600:80bf:4c09:a0d:9c35:30b3
and the MAC address is 6C-62-6D-D1-DF-AD
. Problem solved.
