    Very complicated explanation, not so clear. Lacks some real examples including real keys and records. Too theoretical

  2. v1rtu4l on July 25, 2021 at 8:30 pm

    on 4:05 your picture says that Jamie Lee does decrypt a digest encrypted by Arnolds private key by using Arnold’s public key. By definition you can not decrypt with a public Key. i think you meant that Jamie Lee does encrypt the hash of the sent document and then compare that to the send encrypted digest. am i right ?

    Does this mean dnssec is not depended on HTTPS digital signatures? so digital signatures we receive on HTTPS are different to digital certificate of DNSSEC?

    Great video but I would recommend raising the volume a bit. I struggled to hear you even with my volume all the way up. I appreciate the effort regardless!

  5. lastyledotch on July 25, 2021 at 8:32 pm

    Hi Daniel,
    Nice explanation but why should a company use DNSSec? There are too much arguments on the web which shows it more risky than using it: http://sockpuppet.org/blog/2015/01/15/against-dnssec/

  6. Rafael Castro on July 25, 2021 at 8:33 pm

    Great explanation, I lost some hours trying to understand the DNSSec and now, I got everything I need. Thanks for the good material.

  7. Caio Valente on July 25, 2021 at 8:33 pm

    thanks a lot!

    very good video. cleared the concept . cloudflare also has some good articles / blogs written on dnssec and complexities it brings in.this video and those blogs should be good starting point for everyone

  9. Tomáš Plachý on July 25, 2021 at 8:34 pm

    This is a great video, but it would be even better, if you highlighted the parts you are currently talking about (since it is a bit difficoult to orientate in all the items).
    Anyway thanks for the explanation, it helped a lot.

    The best explanation of DNSSEC on youtube

  12. PETAJOULE543 on July 25, 2021 at 8:42 pm

    Motivation of DNSSEC and also its detailed explanation. Also, the difference between iterative and recursive dns queries.

    very low volume+++++++++++

  17. BookMyIdentity on July 25, 2021 at 8:49 pm

    Every aspect of the DNS should be known to you before you embark on your journey towards registering a domain name! BookMyIdentity offers reasonably priced domain name registration services!

  18. Luis López on July 25, 2021 at 8:50 pm

    Terribly good explained. There are tons of videos pretending to explain DNSSec, yours do it for real!!! Very well done. Thanks a lot.

    Great job interpreting DNSSec for secure domains. Google’s future prospects on the Internet include encryption – a secure connection (HTTPS) is required for all websites. Google has implemented unsafe warnings for domains. Google will block (HTTP) domains next year or so.

    Good attempt and appreciate your effort , BUT the font on slides is so hard to read and wrong colour scheme used for the diagrams.

  22. MIRIYALA JEEVAN KUMAR on July 25, 2021 at 9:04 pm

  23. fbi fido on July 25, 2021 at 9:05 pm

    why can’t the Root zone, be the one to comunicate to the TLD, then the TLD comminicate with the DBL zone, all using dnssec, then the root reply with the correct answer?

  24. fbi fido on July 25, 2021 at 9:08 pm

    @9:02 why not just encrypt the request with the root pubksk, then send it to the root server, with your own public-key?

  25. TheBPandey on July 25, 2021 at 9:09 pm

    This was great! Clear explanations.Thanks for taking the time to make this.

  26. preeti dutta on July 25, 2021 at 9:12 pm

    Awesome slides Daniel

  27. Hamidullah Muslih on July 25, 2021 at 9:13 pm

    thank you sooooo much that was awesome

  28. Ali Entezam on July 25, 2021 at 9:15 pm

    Very well explained. Thank you !!!

  29. nah dude on July 25, 2021 at 9:19 pm

    A goog presentation does not make its presenter obsolete. This does!
    A more visually supportive presentation would have been miles better and easier to create.

  30. poisonousblood on July 25, 2021 at 9:21 pm

    Thank you for the awesome explanation!

  31. Mihail Colun on July 25, 2021 at 9:22 pm

    Yooo man
    You are the real MVP
    Current MCSA books don’t give a thing about this terminology and explanation
    I don’t have any DNS practice, and i was struggling understanding DNSSEC from 70-741 exam
    Thanks a lot

  32. Anand Sundaresh Natarajan on July 25, 2021 at 9:24 pm

    Very well presented. Have seen a lot of content for DNSSec but havent found anything as clear and concise as this.

  33. darmath2009 on July 25, 2021 at 9:25 pm

    In the event that you utilise the slides to give presentations on this topic, please consider the colour that you utilise throughout the slides. Due to the colour that is utilised the slides can be difficult to read.

  34. sheikh baseer on July 25, 2021 at 9:26 pm

    Awesome Explanation…Kudos.

  35. hyna kydla on July 25, 2021 at 9:27 pm

    Great video even dummy as me got it.

  36. Three One on July 25, 2021 at 9:28 pm

    Fantastic explanation!
    Somebody needs to put you in charge of something. You know what you’re talking about.

  37. Stanley Kwong on July 25, 2021 at 9:28 pm

    Very well made slides! Although I don’t really think there’s a point to making this a video/narrating over it if you just read completely off the slides.
