What is used in the EUI-64 process to create an IPv6 interface ID on an IPv6 enabled interface?

  • the MAC address of the IPv6 enabled interface
  • a randomly generated 64-bit hexadecimal address
  • an IPv6 address that is provided by a DHCPv6 server
  • an IPv4 address that is configured on the interface

Explanation: The EUI-64 process uses the MAC address of an interface to construct an interface ID (IID). Because the MAC address is only 48 bits in length, 16 additional bits (FF:FE) must be added to the MAC address to create the full 64-bit interface ID.
