Networking Fundamentals: A Comprehensive Crash Course

In this video I explain fundamentals of the most important networking technologies, e.g. IP addressing, Routing, Switching, TCP, DHCP, DNS, BGP, NAT and VPN. All these topics are important to understand if you are building networks in cloud. While some topics like BGP, VPN and switching can be omitted by non-network engineers, the rest of topics are important for all IT engineers, including application developers and DevOps. Let me know in the comments if this was helpful.
