Guide on IP Addressing

An IP Address is a unique set of numbers that identifies each computer using the Internet Protocol to communicate over a network. It is important as it allows a specific computer to be identified in a network.

How IP Addressing works: Every machine on a network has a unique identifier. Just as you would address a letter to send in the mail, computers use the unique identifier to send data to specific computers on a network.

In IP version 4 (IPv4), a IP address consists of four numbers separated by dots. Each number can be zero to 255. For example, 192.168.100.1 could be an IP address.

In IP version 6 (IPv6), an IP address consists of eight groups of four hexadecimal digits, each group representing 16 bits. For example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334 could be an IP address.

Exam Tips: IP addressing questions typically involve calculating subnet masks, private and public IP address ranges, or understanding notions about static and dynamic IP addresses.

1. Understand IP address classes: There are five different classes of IP addresses (A, B, C, D, and E). Know how to identify which class an IP address belongs to based on its range.

2. Subnetting skills: be acquainted with subnetting skills to be able to divide IP addresses into subnets.

3. Private vs Public IP addresses: know the difference between private and public IP addresses and they are in which ranges.

4. Static vs Dynamic IP addresses: understand the difference between static and dynamic IP addresses.

By mastering this, you can make sure to get the best score possible in answering IP addressing questions.

IP Addressing practice test

IP Addressing refers to the method of assigning a unique identifier, known as an IP address, to each device connected to a network. IP addresses are used to locate and identify devices in order to establish connections and facilitate communication between them. There are two versions of IP addresses - IPv4, which uses 32-bit addresses, and IPv6, which uses 128-bit addresses. Each version has its unique structure and address space. IP addressing also involves subnets and subnet masks, which segregate networks into smaller groups of devices, simplifying the routing and management of network traffic. Understanding IP addressing is essential for network configuration, troubleshooting, and security.
