It turns out the new job requires deep understanding on how the DNS works. I have a barely shallow idea on it and trying so hard in finding useful resource online to top up some practical knowledge. The first one is really a great example of showcase how to "Explain like I'm 5"(ELI5) on any subject, even a very technical one like DNS. How DNS Works illustrates possibly the full process of DNS lookup via a series of lightly animated comic. Super interesting! And if you need more depth in that topic, DNS for Rocket Scientists is another great resource to consume.
