Annex A Lesson 3 - Addressing Network Fundamentals | Latest Update | 2024/2025 | Already Passed 3 basic characteristics of IP. Connectionless, Best Effort, and Media Independent. 3 types of IP addresses within each network Network Address, Host Addresses, and Broadcast Addresses. 4 different types of devices that require addresses within a network. End User Clients, Servers, Intermediary Devices, and Gateway. 48-bit address expressed using 12 hexadecimal digits. Ethernet MAC address. A digit represents different values depending on the position the digit occupies in a sequence of numbers. Positional Notation. Addresses that can be assigned to a device such as a host computer, laptop, smart phone, web camera, printer, router, etc. Host Address. Alternative method of identifying a subnet mask. Prefix Length. An address that is used when it is required to reach all devices on the IPv4 network. Broadcast Address. Assigning an IPv4 address to a host requires the following. IPv4 Address, Subnet Mask, Default Gateway. Contains 8 bits (or 1 byte) separated with a dot. Octet. Designed to support extremely large networks with more than 16 million host addresses. Class A used a fixed /8 prefix with the first octet to indicate the network address and the remaining three octets for host addresses (more that 16 million host addresses per network). Class A (0.0.0.0/8 - 127.0.0.0/8). Designed to support small networks with a maximum of 254 hosts. Class C used a fixed 24/ prefix with the first three octets to indicate the network and the remaining octet for the host addresses (only 254 host addresses per network). Class C (192.0.0.0/24 - 224.255.255.0/24). Designed to support the needs of moderate to large size networks with up to approximately 65,000 host addresses. Class B used a fixed /16 prefix with the two high-order octets to indicate the network address and the remaining two octets for host addresses (more than 65000 host addresses per network). Class B (128.0.0.0/16 - 191.255.0.0/16). IP is inherently unreliable because packet delivery is not guaranteed. Best Effort. Language that computers use to communicate. A number system that consists of the digits 0 and 1 called bits. Binary. Most networks allocate IPv4 addresses to client devices dynamically, using Dynamic Host Configuration Protocol (DHCP). This reduces the burden on network administrators and virtually eliminates entry errors. End User Clients. Operation is independent of the medium carrying the device. Media Independent. Process used to identify the network portion and host portion. ANDing. Represented using the decimal base ten number system
