    Study Notes

    Network Protocols

    • The primary protocol driving most operations on today's networks is TCP/IP (Transmission Control Protocol/Internet Protocol).

    IPv4 Address Format

    • IPv4 addresses consist of four decimal numbers, known as octets, separated by periods (e.g., 192.168.1.1).
    • Each octet can range from 0 to 255, allowing for a total of 256 possible values per group.
    • An IPv4 address is 32 bits long.

    Binary Representation

    • The binary representation of the decimal value 192 in an IPv4 address is 11000000.
    • The binary representation of the decimal value 168 in an IPv4 address is 10101000.

    IPv6 Address Characteristics

    • IPv6 addresses are 128 bits long.
    • They are divided into eight groups of four hexadecimal digits, separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

    Subnet Mask

    • A subnet mask is used to determine the network and host portions of an IP address, facilitating efficient address allocation.
    • Commonly, the subnet mask for IPv6 addresses is written as /64, indicating the first 64 bits are used for the network prefix.

    Minimum Configuration for Network Connectivity

    • To achieve network connectivity, a device must have an IP address, a subnet mask, and a default gateway configured.

    Default Gateway

    • The default gateway acts as an access point to other networks, allowing devices within a local network to communicate with external networks.

    DNS Server Role

    • A DNS (Domain Name System) server translates human-readable domain names into IP addresses, facilitating easier navigation on the internet.
    • Two DNS IP addresses are typically assigned for redundancy, ensuring continued connectivity if one server fails.

    Importance of Unique IP Addresses

    • Each device on a network must have a unique IP address to prevent address conflicts and ensure accurate delivery of data packets.

    Network Communication Utilization

    • Routers and other devices query DNS servers to convert domain names to IP addresses, enabling communication with external resources.

    Summary of Address Formats

    • IPv4 addresses are typically displayed in decimal format, while IPv6 addresses are displayed in hexadecimal format.
