  C. The seventh bit of the original MAC address of the interface is inverted. In the process of generating an EUI-64 address, the 48-bit MAC address of the interface is taken, 16 bits are inserted (usually zeros), and then the seventh bit is inverted. This results in a 64-bit EUI-64 address used in IPv6 for interface identification.
