- - - - Structure of IPv4 Address
        
        • Each IPv4 address is made up of four groups of
        numbers, that range from 0 to 255, separated
        by a period.
        
        • Examples of IPv4 addresses:
        – 10.20.20.16
        – 172.16.200.99
        
        • IPv4 address has two parts:
        – The network part (first three numbers) identifies
        the network.
        – The machine part (last number) identifies the
        specific computer.
        
        • Example:
        – 10.20.20.16
        • 10.20.20 (network part)
        • 16 (machine part)
    - - The importance of IPv6
        
        • The Internet has experienced a phenomenal
        increase of devices accessing the Internet.
        
        • Because of this increase, IPv4 addresses are
        running out.
        
        • The solution is for IPv6 to accommodate this
        increased demand by providing a much larger
        address space, along with improved traffic
        routing and better security.
      - Advantages of IPv6
        
        • Larger IP address space - provide enough
        address space for many decades to come
        
        • Better security
        
        • Better support for real time
        
        • Includes Plug and play
        
        • Better optimization
      - Structure of IPv6 Address
        
        • Each IPv6 address is represented as eight
        groups of four hexadecimal digits, separated
        by colons (:)
        
        • Examples of IPV6 address (full notation):
        – 2001:0db8:00a7:8ac4:0234:7bff:fe19:223c
        – 2001:0db8:0a0b:12f0:0000:0000:0000:0001
        
        • Example of IPV6 address (compressed format):
        – 2001:db8:a0b:12f0::1
