DNS Essentials - Understanding & Working With DNS 

If you want to understand DNS Essentials, this is a good one. Concise and to the point covering DNS essentials. Thank You.

this is actually the best video for explaining DNS and the related topics in an easiest way. Precise and to the point.

Bro, I wish I could thank you for how easy and simple to understand you make it seems. Being having issues setting up my own hosting for some websites and this has finally cleared my mind into understanding the whole DNS process. Regardless that I was using Linux, I was able to replicate pretty much everything. Thanks again.

Thank you John! I was curious about DNS and this lesson is certainly a foundation in DNS. I was more interested in how a web hosting company, can host multiple other, unrelated domains. To understand what I wanted, I needed to grasp the concepts in your video. Great work, good pace, easy to understand. I would definitely watch another video created by you.

Excellent - Simple and crisp! Thank you !

It's 2034 and this is still the best DNS explanation video ever!

Broken into bits, from the host file, the resolver cache, local dns, dot all the way down to the www, great video!!!!

I have never seen such an amazing video... It has all the details needed to understand dns ... thanks a lot

Great work, i am extremely thankful for this material, as i have been struggling since 1 week to point my domains to my server.

This is very good tutorial. I did not understand it after I watched it for the first time. But after reading theory about DNS structure everything is on its places. Great work! Thanks a lot!

Finally a good tutorial well explained and easy to understand. Thanks !

This video in a nutshell touches most of the concepts and terminologies..thank you

Excellent dive into DNS ... A great brush up for me on how DNS works. I had a look at DNS on Server 2016 after following your Active Directory video. I wondered why it didn't do Reverse-DNS by default.

best tutorial explaining DNS....Thank you

Very informative video to understand DNS basics in a simple manner. Thanks.

God bless. Your teaching skills are excellent. Its so easy for me to grasp an understanding of the topic. Thank you very much John.

Great practical content. Thank you

Subscribed and liked, thanks please do more in depth. Like building a hyper v servers network for multiple locations and zones, more like a lab environment for testing.

Excellent video. Concise, informative and very well presented.

I never comment but this video really deserved a kudos. Thank you for such a succinct introduction to DNS!

Great help! Appreciate the video :)

very useful - I learned a lot. Thank you very much!

Thank you for this great tutorial. I got a bit confused in what the difference is between a name server and a DNS. Or what is the Name Server in general. Especially here 14:40. Is the name server just this window with records you have open there and DNS is the entire thing? And since you updated the host there does that mean this is the Primary Name Server and the NS record has the value of the server you are on right now?

Great Stuff

Magnificent, Thank you v.much

Thanks for the video

excellent tutor

I want to map my subdomain eg.cloud.abc.com to my file server which is public ip so what record I should add in my DNS server

Good video...Thank you Sir : )

Great video,

Crystal clear .thanks

hi can you explain how dns rebinding works in depth ?

good explanation !

Thanks for this!

Thank you!!

I have reviewed the video - still as good as ever. A couple of questions on second viewing. 1) During the explanation of the workstation iterative query, you say the DNS server looks in its local cache and zone database file for the IP address. Is the zone database file the equivalent of the hosts file that the workstations has? Just a different name because it's on the DNS server? Or can the server also have a hosts file in addition? 2) You mention the SOA record as indicating the server is Authoritave. And then you mention the Name Server record as being a pointer to the DNS server. The distinction is a bit foggy for me. Can you elaborate a bit on the differences between these two records. I think the use of server for both is confusing. Can you give an example of where the two would be different? 3) In your NSlookup examples you query at one point without specifying the name server and you say that the client - I am assuming the resolver on the workstation - then uses the default name server? Where does this default come from? In the hosts file of the client? Thanks in advance for further clarification.

Hi, may i know what will happen if the forward lookup zone was not configured?

Hello! And once I set up the DNS role, as a must, together with the Domain Controller role, it is necessary to give the newly created DNS, DC server IP as DNS IP for all the client PCs (to be) registered within the domain. Is that correct? Thanks.

That was great. Could you do a similar tutorial on Mac OS X? There are some finnicky things with dns on a mac such as .local being used by Bonjour

Thanks for clearing my DNS doubts, I have a question in my mind, does DNS go every time to root server to lookup the IP/s? Also does every time the communication between Zone Transfer happens on TCP 53 or it depends on what configuration did on the DNS server for communication TCP/UDP 53?

how would you let other dns servers like 1.1.1.1 or google nns see your dns record and check if you have the rigth path to follow if it dossent have a record like that in its database?

best DNS video on youtube. Hopefully you can make one with more detail, such as creating zones and doing more in windows server 2012. I'm also a little unclear on how you use the CNAME records. If you just type ftp in the address bar, will that take you to server3.ittaster.com directly?

The local DNS Server first queries in its database and then in its cache? Shouldn't it be the opposite since cache is easier to access?

Great video. One question. In your zone file you have 4 A records. The last three are associated with servers in the first column. However the first one has no name in the first column and a time stamp in the last column. It seems to point to .200 which is the same as Server 1. What is its purpose? Thanks in advance.

this is the simplest way of explanation.

thanks

Very useful Thank u sir..

nice :)

please bring new videos on Azure AD and O365. Also other Microsoft cloud concepts.

I am in fog with that example .local, that lead me in abiss :) . U could use a real fqdn server as an example. Btw most of ppl are interrested to make small projects at home for web servers or other aplications and like 90% of them use dynamic ip.s. When we add dns records with cname to point ddns where exactly place the record? I am not sure how to point that cname record . The ddns is basic fqdn ? for example ddns.com is a fqdn domain and offers dynamic domains by adding "subdomain" at mai domain so we get like nameserver1.ddns.com ? Is that right? So now that name define our connection. And on a webserver when we create websites at those website we add cname records with nameserver1.ddns.com?

Windows give me to the nerves with their complex settings .
