IPv4 Tutorial

If you are beginning your journey into networking or preparing for a certification like CCNA, having a solid understanding of IPv4 is essential. Internet Protocol version 4 (IPv4) is the fourth iteration of the Internet Protocol and is the foundation of most networks today.

IPv4 uses a 32-bit address scheme allowing for a total of 232 addresses. These addresses are typically represented in dotted decimal notation, such as Understanding how to subnet IPv4 addresses is crucial for proper network design and management.

In this tutorial, you will learn about the structure of IPv4 addresses, including the network portion and the host portion. You will also delve into different classes of IP addresses, including Class A, Class B, and Class C, and how they are used to cater to different network sizes.

Furthermore, you will explore the IPv4 packet structure, which includes the IP header and payload. Understanding the fields within the IPv4 header, such as version, header length, type of service, time to live, protocol, source address, and destination address, is key to comprehending how data is routed across networks.

By the end of this tutorial, you will have a solid grasp of IPv4 fundamentals, enabling you to configure IP addresses, subnet masks, and default gateways on network devices. This
