This was recorded 8 years ago and the quality is top-notch and much better than most of today's videos. This says a lot and I wish that you make more videos like these. Thank you :)

Great video Barry. Have you also made the video for DNS cache flushing ? It would help.

4:14 you said "this is the google dot com domain". That's actually wrong. It should be pronounced as "this is the google dot com “dot” domain". The last dot actually matters in DNS terminology. Because the root ("dot") itself is a domain, too.
