Networking 101: DNS Revealed

Two great new ‘Networking 101’ videos now available.  This series is great for anyone needing a quick refresh or touch up on the basics and these two both focus on DNS.

DNS is key to making the Internet accessible to us humans. It’s how we can connect to techwisetv.com without needing to know anything complex from anywhere in the world. How does it know how to do this? DNS can be a complicated topic but understanding the basics does not have to be.

Taking it a step further, DNSSEC is a suite of IETF specifications designed to guarantee the authenticity of data obtained from the domain name system (DNS). Although not designed for confidentiality of the data, this protocol is a great answer for many of the ills that threaten the simplicity of the Internet. Chief Geek Jimmy Ray Purser arms you with how it works and why deployment is not growing as fast as it should be.
