    What is preferred to use as a DNS server? Iterative or recursive and why?



  14. Sokret Heng on March 19, 2021 at 1:52 am

    Very clearly. Thank you sir



  15. Scott Palmer on March 19, 2021 at 1:54 am

    This is not in depth. This is more like an overly verbose introduction to DNS.

  21. sumedh damodare on March 19, 2021 at 1:58 am

    What if my primary dns server is shut down….will its query be resolved by an alternate dns server?
    And what if both goes down.

    We have two 2008r2 dcs . We are going to demote them,keeping the dns service. Both this dcs are primary and alternate dns servers to clients



  22. Sunil N on March 19, 2021 at 2:00 am

  28. SOURAV DAS on March 19, 2021 at 2:05 am

    Excellent explaination! đŸ€âœŒïž



  29. Michael Taylor on March 19, 2021 at 2:06 am

    Correction, putting entries in the host file does NOT input it in any cache.

    DNS is always (by default on linux/windows/mac) queried 2nd, the first query will always check your host file first. You can modify the order of lookups on linux by flipping the order within the /etc/nsswitch.conf file, not sure about doing this on windows but it maybe possible in the registry somewhere.



  30. Just Epic Videos on March 19, 2021 at 2:06 am

    iirc, this is not an iterative query, ISP dns server(dc01 in your video) is a recursive server, that always manages all requests by himself and collects answers. Servers like root, and tld would either forward you or send an error. That is called iterative. Correct me if im wrong



  31. Koffi Anicet Kouakou on March 19, 2021 at 2:07 am

    I just discovered you! Great explanations!



  41. Amar Chhabra on March 19, 2021 at 2:19 am

    What OS are you using? Windows Server? Trying to figure out how to get to DNS Manager screen.



  42. Shane Black on March 19, 2021 at 2:19 am

    explained really well. i think i finally get how it works. thanks



  43. Mihail on March 19, 2021 at 2:20 am

    Awesome explanation, thank you! One question, I hear of SOA is that like going to the root DNS and the root DNS updates all other DNS Servers with the new IP’s when users request a specific IP? does that make sense?



  44. Sneha Sarkate on March 19, 2021 at 2:21 am

    This is the best tutorial…. Cheers!!



  45. WarDisciple1 on March 19, 2021 at 2:22 am

  50. Luke Hester on March 19, 2021 at 2:25 am

    Thanks. The last part about how Windows appends the DNS suffix is very useful to know.
