    Study Notes

    IPv4 and IPv6 Addressing

    • IP addressing is a fundamental component of computer networking, enabling devices to identify and communicate with each other on a network.
    • Two primary versions of IP addressing exist: IPv4 and IPv6.

    IPv4 Addressing

    • IPv4 is the fourth version of the Internet Protocol (IP) and has been the dominant addressing scheme since its inception.
    • Developed in the 1980s, it provides a unique identifier for each device on a network.
    • An IPv4 address is a 32-bit number, expressed in dotted decimal notation using four octets (8-bit groups) separated by periods (e.g., 192.168.0.1).
    • IPv4 addresses are categorized into classes (A, B, C, D, E) based on network and host bit sizes.
      • Class A (1.0.0.0 to 127.255.255.255): 8 network bits, supports 16 million hosts.
      • Class B (128.0.0.0 to 191.255.255.255): 16 network bits, supports 65,534 hosts.
      • Class C (192.0.0.0 to 223.255.255.255): 24 network bits, supports 254 hosts.
      • Class D (224.0.0.0 to 239.255.255.255): Multicast addresses.
      • Class E (240.0.0.0 to 255.255.255.255): Reserved for future use.
    • IPv4 also has private address ranges.
      • 10.0.0.0 – 10.255.255.255
      • 172.16.0.0 – 172.31.255.255
      • 192.168.0.0 –  192.168.255.255
    • These private ranges are not routed on the internet.
    • Subnetting allows dividing a network into smaller, more efficient subnetworks by borrowing bits from the host portion of the address.
    • A subnet mask defines the boundary between network and host portions (e.g., 255.255.255.0).
    • IPv4's limitations include address exhaustion.

    IPv6 Addressing

    • IPv6 is the next-generation IP addressing designed to address the limitations of IPv6.
    • Uses 128-bit addresses for a vastly larger address space (~3.4 x 1038 addresses).
    • Written in hexadecimal format, with eight groups of four hexadecimal digits separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
    • IPv6 addresses can have leading zeros omitted, and consecutive zeroes compressed using double colons (e.g., 2001:db8::20).
    • Three address types: unicast, multicast, and anycast.
      • Unicast: Single sender, single receiver.
      • Multicast: Single sender, multiple receivers.
      • Anycast: Single sender, nearest receiver.
    • Different address types are defined by their prefixes
    • IPv6 use cases include future network growth, improved security through built-in IPsec, and simplified header structure for more efficient routing.

    IPv4 vs IPv6

    Feature IPv4 IPv6
    Address Length 32 bits 128 bits
    Address Format Decimal (e.g., 192.168.0.1) Hexadecimal (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334)
    Address Space ~4.3 billion ~3.4 x 1038
    Header Complexity Complex with options and checksum Simpler, no checksum
    Security Optional IPsec Mandatory IPsec
    Configuration Manual or DHCP Autoconfiguration
    Broadcast Support Supports broadcast No broadcast, uses multicast
    Routing More Complex More efficient

    Transition from IPv4 to IPv6

    • Dual Stack: Existing devices and networks run both protocols simultaneously.
    • Tunneling: IPv6 packets encapsulated within IPv4 packets for transmission.
    • Translation: IPv4 and IPv6 addresses can be translated using protocols like NAT64.

    Addressing Use Cases

    • Internet devices: IPv4 remains widely used.
    • Network devices: IPv6 is increasingly used in next-generation networks.
    • IoT devices: IPv6 is better suited for supporting the growing number of IoT devices.
    • Mobile networks: IPv6 offers more efficient address allocation, thus suitable for mobile networks.

    Conclusion

    • IPv4 and IPv6 are critical for modern networking, each serving distinct needs.
    • IPv6 is a future-proof solution addressing IPv4's limitations particularly address depletion.
    • Continued growth and scalability of the internet depend on IPv6's capability to adapt to expanding network demands.
