QuestionQ158

IPv6

You are a network administrator for BlueWell Inc. You must convert your 48-bit host address (MAC address) to an IPv6 54-bit address. Using the IEEE-EUI-64 conversion process, how do you convert the 48-bit host address (MAC address) into an IPv6 54-bit address?

  • A Add EF. FE between the third and fourth bytes.
  • B Add FE. EE between the third and fourth bytes.
  • C Add FF. EE between the third and fourth bytes.
  • D Add FF. FE between the third and fourth bytes
Explanation

The IEEE EUI-64 conversion forms the interface identifier by inserting FF:FE between the third and fourth bytes of the 48-bit MAC address. The universal/local bit of the first byte is also inverted as part of modified EUI-64 generation.
