Domain Name System DNS

This video is about the Domain Name System (DNS), a global system in which user friendly domain names are translated into IP addresses. It outlines what takes place when a client computer needs to contact a web site, including the roles of the Internet Service Provider’s recursive resolver, the root name server, the top level domain (TLD) servers and the authoritative name servers. The video also includes the benefits provided by the DNS distributed architecture.

    Great Video.

    Just a little feedback:

    At time 3:25 in video: the sequence of 128 bits can be written as 32 Hexadecimal numbers (and not 8 Hexadecimal numbers.)

    Hope this is helpful.

    I think its a good idea if you follow up on this video by making one that talks about DNS Amplifications attacks, DNS poisoning, and DNSSEC

    Great video, thank you. P.S. I like how the British people pronounce the letter "h", this is epic.
