  1. Internet Protocol Version 6 (IPv6)

    Slide 1 - Internet Protocol Version 6 (IPv6)

    • Uses 128-bit IP addresses (versus 32 bit for IPv4)
    • IPv6 is expressed in hexadecimal numbers
    • 32 numbers and letters, 0–9 and A–F
    • First 16 hexadecimal digits are network ID, last 16 hexadecimal digits are host ID
    • Example: 13D4:FA97:0000:1258:AD8B:1009:34D6:1800
    • No subnetting needed
    • So you have to learn HEXADECIMAL for IPv6(Don’t worry – it is not hard)
  2. Binary to Hexadecimal Conversion

    Slide 2 - Binary to Hexadecimal Conversion

    • First, learn how to convert binary to hex
    • Replace every four 1s and 0s with the equivalent hexadecimal value
  3. IPv6 Address Double Colon Technique

    Slide 3 - IPv6 Address Double Colon Technique

    • Not all 16-bit groups in IPv6 address need to be shown
    • If IPv6 address has a group of 16 bits equal to all 0s, that 16-bit section can be skipped
    • 13D4:0000:0000:0000:0000:1009:34D6:1800
    • can be written as
    • 13D4::1009:34D6:1800
    • This block of zeroes can be abbreviated
  4. EUI-64

    Slide 4 - EUI-64

    • Extended Unique Identifier (Feature of IPv6)
    • Host can automatically assign itself a unique 64-bit interface identifier (a larger MAC Address)
    • Two steps:
    • Divide MAC address between the Organizationally Unique Identifier (OUI) and the host portion of the MAC address
    • Add hexadecimal value FFFE between two portions of the MAC address
    • What’s EUI-64?

  5. EUI-64 (Continued)

    Slide 5 - EUI-64 (Continued)

    • Invert 7th bit of MAC address so it is opposite of what it was previously
    • This bit is called the universal/local flag
    • Normally set to 0; to invert, change to 1
    • Result is a Modified EUI-64 address
    • Can be used by IPv6 as a unique interface identifier on a device connected to a network
