IP Addressing Fundamentals: IPv4, IPv6, Subnetting & Network

About this course

This course contains the use of artificial intelligence.Understanding how devices communicate on a network is one of the most important skills in IT, networking, cybersecurity, and cloud computing. At the center of this communication is IP addressing.In this course, you will learn the fundamentals of IP addressing in a clear, structured, and beginner-friendly way. Whether you are completely new to networking or looking to strengthen your foundational knowledge, this course will guide you step by step through the essential concepts used in real networks.We start with the basics of IPv4 addressing, including how IP addresses are structured, how devices use them to communicate, and the differences between public and private IP addresses. From there, you will learn about static and dynamic IP assignment, the role of DHCP, and important reserved addresses used in networking.You will also gain a solid understanding of subnetting, including subnet masks, CIDR notation, and how networks are divided into smaller segments. These concepts are critical for managing modern networks efficiently and securely.The course then introduces IPv6, explaining why it was created, how IPv6 addresses are structured, and how they compare to IPv4.Finally, we explore practical networking concepts, including how routers and NAT work in home and business networks, how to find your IP address on different operating systems, and how to troubleshoot common IP addressing issues.By the end of this course, you will have a strong foundation in IP addressing that prepares you for further study in networking, cloud computing, and cybersecurity.This course is also helpful for learners preparing for networking certifications such as Network+ or CCNA.<
