Suggest me some exercises to do to learn DNS?

[networkloser]

I've these textbooks

- Comer's tcp ip internetworking
- Fourouzan's networks
- Kurose Ross networks


But I'm not seeing any exercises in this books that are helpful to deepen my understanding.

I like the exercises like this:

The computer science department at purdue university chose to place the following type A record resource record entry in its domain name server:
localhost.cs.purdue.edu 127.0.0.1

Explain what will happen if a remote site tries to ping a machine with domain name localhost.cs.purdue.edu.


How can I simulate this on my linux machines?

How can I simulate this on my linux machines?

you can run bind on your linux machine, it is a DNS server. then you can test whatever you want for the most part locally.
you could probabbly setup a VM that runs bind, and then try to ping from local machine to VM running bind
