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.
