Can’t rely on the windows randomly generated IPV6 address. In the first octect of the OUI part the second bit indicate if the address is unique or not. The second part is not completed clear to me. Im understand the first part of the conversion about inserting FFFE code between the part or the MAC address OUI and the ID part. Therefore if I want to parse the WDS log files to identify each PC in the logs I need to construct the IPv 6 address using the EUI-64 method. I would like understanding MAC to EUI-64 conversion mechanisim. This site explains, the Windows does not use the Mac address to generate the IPv6 LinkLocalAddress IPv6: How Windows generates Link-Local Addresses (EUI-64) – SID-500.COM. We are talking about the same Ethernet device. The windows IPv6LinkLocalAddress value for that device is fe80::6d8d:28d8:191b:3f30%3 in this example the WDS server show a log entry such as : The WDS Bitlocker network unlock logs show the IPv6 Link local address of the physical device when the client PC is booting, and it the PC’s UEFI bios that send’s out the Network unlock request. I agree simple is better but in this case it does not work, The WDS logs are obtained in this manner $WDSEventsVerbose = Get-WinEvent -cn $WDS -EA silentlycontinue -FilterHashtable = (Get-Netadapter -CimSession $Script:RemoteCimSession | Where-Object įor remote systems just use PSRemoting as normal. I am parsing WDS network unlock logs and want to identify source computer. I got starting by getting the Mac I am interested in. Note the that IPV6 address obtained by the ipconfig / Get-NetIPAddress are not suitable for my needs, these address obfuscate the Mac address. prepend the link-local prefix: fe80::5074:f2ff:feb1:a87f.replace first octet with newly calculated one: 5074:f2ff:feb1:a87f.convert octet back to hexadecimal: 01010000 -> 50.convert the first octet from hexadecimal to binary: 52 -> 01010010.reformat to IPv6 notation 5274:f2ff:feb1:a87f.
