I checked my Link-Local on my computer and it doesn't contain my MAC address for the EUI-64 scheme. Any thoughts on why not?
IPv6 Link-Local Assigning
If you're seeing something like:
This is normal behavior in Windows OS, it's a format they use to help identify the different interfaces. With Windows Vista and Server 2008 and later, the OS generates a random interface ID.
You can disable this behavior using netsh:
netsh interface ipv6 set globaal randomizeidentifiers=disabled
Now you may be wondering..."ok, why?" Well believe it or not, Windows believes the RFC 2462 process for autoconfiguration is too slow--Remember, it has to send out messages, and wait for Duplicate Address Detection (DAD) to work before assigning itself a number. So Windows OS instead, does a random number generation and adds the interface identfier %##. This make's it faster, according to Windows!

Makes sense and answers it perfectly. Thanks Ronnie, and yes it is a Windows machine.
