Whether you are pursuing your Cisco CCNA Certification, or just need a refresher on IPv4 addressing and subnetting, this is the course for you. This course covers the very early days of the ARPANET and why TCP/IP was first developed. It then goes into details about the evolution of IP addresses from when only the first byte was considered the “network”, to Classfull Addressing, to Subnetting, VLSM and CIDR. IPv4 address Summarization and Supernetting also included. As an extra bonus, these videos contain many “quiz” slides and their associated answers giving you the opportunity to pause the videos, answer the quiz, and then verify your answers.
