I want to know somthing about the GUID....
That generated ID is really unique...
If i am not on inet or if i dont have ethernet card..the is it such that GUID assigned by me to the interface is useless??Or i cannt use it if i am on net.??
Will it face problem like Y2k after some years as the ethernet cards nos will be over ....this may be a foolish question i guess but sorry for that...

Can Anybody also tell me that how the IEEE is taking care about the unique numbers given to the Ethernet cards..
Thanks a lot.
