IPv6

  • 128 bits
  • Written as eight blocks of hexadecimal numbers
    • Last four blocks identify the interface
    • First four blocks identify the network
      • Serve as the network prefix
        • Also called site prefix or global routing prefix
    • Fourth block in the site prefix can be altered to create subnets

Subnets

  • Subnetting is simpler than IPv4
    • Classes not used
    • Subnet masks are not used
  • Subnetting helps admins manage the enormous volume of IPv6 addresses
