I'm here from The Odin Project 👋 How about you?
Here from the amazing odin project! great video!
Odin project people over here! :D
I'm going to school for networking and I know what DNS is but it's very complex and just never really caught on for me. This video was done great and although I'm sure DNS is even more complex then what was showed in this video it did help clear some things up. Thank you for taking the time to make this amazing video.
I didn't really take much in but that was cool.
We should have such videos for all concepts ....
+Nadiia Chepurko I completely agree.
We are committed to making the understanding and managing of DNS easier for everyone, but that doesn't make the domain name system itself any less complex. Our aim here was to simplify the process as much as possible so that almost anyone could grasp it.
Was there anything in particular you wanted more information on?
Holy shit...explained what took my professor 30min.
Thank you for the kind words! We are actually in the process of coming up with more content, however, the bulk of it will be based on DNS as that's our primary business. We apologize for the inconvenience, but hope you will enjoy our future offerings all the same!
We actually produced this video in house. Drop us a line if you'd like to see more work from the same guy.
It is so creative! You managed to explain a pretty difficult system in such a simple way!
Thanks a lot!!!
Just one word TOP
Thanks! Just using Illustrator, Photoshop, and After Effects.
Good question! The resolving name server is actually provided by your ISP unless you're using a third-party resolver. In essence, your operating system is contacting your ISP (resolving name server), which contacts the Root name server.
Glad to hear it! There are tons of resources on our site and channel if you ever find yourself wanting to learn more about DNS.
The browser and OS forgot to put the IP address in their own cash (or as cool kids call, *cache*)
Best video about DNS EVER!
I laughed and learned something new im really grateful for this video,please keep making more stuff maybe even on different topics.
Thank you! We're constantly trying to increase awareness and knowledge of DNS so that's good to hear. As for good books? If you're looking to learn more about DNS I'd recommend "DNS and BIND". Very comprehensive.
I easily understood this. Hope i can see this type of explanation for other concepts as well. So cool!
I encourage whoever made this video to create a CZcams channel with more of these videos with broader topics... It can be about any other thing, not just computer related topics. He's got the potential.
Very well done. Thank you for the tutorial. The humor was great. Entertaining.
@AutoPsychotic Sorry if that's the impression you got. What we are saying is that the end dot is part of the URL, and that if you type it in at the end you will still get to where you are going. When we said "Go ahead, try it out. We'll wait." That's what we meant. We never meant to infer that the dot would appear.
thanks for making this easier to understand! this helps a lot on the days when my brain wanders off for too long during lectures in class lol
@opikech Great question! If you were viewing content on an intranet you would in fact bring up a web page using that sort of IP address. The reason we used it in our example was because we needed an IP address that was unroutable as we didn't want to run the risk of any viewers visiting a live IP address.
DNS is so confusing but this video explained it in such a simple way, now it make perfect scene. Thanks!
Glad to hear it! We created this video to inform and educate so it's great to know that good people are using it to do just that.
DOUBLE U DOUBLE U DOUBLE U
Finally, an explanation in English.
👍
This is the best video I have seen in a while :)
Going to share with my Web Design class. Thanks.
What a great video! I wish if all the networking concepts had videos like this one here. I would not doze off then.
Love it! Wish my Computer Basics Professor had been this good at explaining things! LOVE the Stephen Hawkins cameo ;)
After Effects, Illustrator, and Photoshop. Though the audio was handled in Audition.
Awesome video. Helped with my revision. Thanks!
简直就是教科书。such a great job!!!
@AutoPsychotic It's never displayed by default. Try going to a website and throwing the dot in at the end of the URL. You'll still get there.
@1111Davo1 Good point. Since our run time was already pushing past the 6 minute mark we elected to not go into too much extra detail (see the 30 second mark), regarding TLDs, who's responsible for the resolving name servers, etc...
We are currently working on a companion article to accompany the video however, and that will include more info about the various TLDs, amongst other things.
The resolving name server queries the root name servers which provide the TLD name servers as their response. Hope that helps!
You've gotta check out our video "The Importance of DNS" to hear about them ;D.
"THE ROOT" !!!!!
*HILARIOUS*
This is a great vid that easily explains it better then I could!!
This is a wonderful presentation. It's indeed DNS made easy. Thanks
Sure thing! DNS Made Easy is actually neither of those. A Registrar is a company that sells domain names, while the Registry is the organization in charge of setting the rules for and managing a top level domain. They also create domain name extensions. DNS Made Easy is an authoritative DNS provider. We basically direct traffic to your site by looking up the IP address of the domain name you type into your browser.
The way u explained the details were very entertaining... Keep it up....
Any time! Thank you for taking the time to view and comment. I'm glad we could help eliminate some of the mystery of this complex and vital system.
What happens if a TLD name server does not have a certain ANS in its database? Does the computer go back to the RNS and try another one?
Can you explain the difference between Registrar and Registry? Is DNS Made Easy a registrar or registry? So authoratative name servers belong to which one? It's little bit complicated for me. Thank You !
We're using private IPs to keep people from accessing potentially hazardous content. All the IPs are for demonstration purposes only.
i have a question about google chrome. Occasionally, i will get an error that says "ERROR_DNS_PROBE_FINISHED". What is a DNS probe?
Thanks! It's really complex to me..
Too much silly, great info.
Which of the servers rely on the dry sarcasm presented here? ...or was that just a bonus? :)
I wanted to ask what software do you use to create these animated videos?
Outstanding video! Great way to learn. Love the graphic design!
You are worthy of millon thanks for such an awesome video of DNS and I Really laughed loudest at Mr steven Hawkins part.
i've tried for www.amazon.com
and,,,page eded up loading and,,,i am actually seeing the same WWW.AMAZON.COM(with no fullstop in the end) in the url bar,,,,and no changes were made to what i actually typed
Man this is a really slick video. Does anyone know what software was used to create the animation?
This is really an awesome way of explaining and making anyone understand what is DNS. thanks !!
Awesomely made! Wholly insightful!
very cool video!!!thank you for the explanation!!if only my teacher could teach like this1!
Excellent! We're glad to hear that people are taking advantage of the material.
what is the name of the software which you used for this Video? I like the Animations really :)
I don't get the dot at the end of any URLs I type in my address bar.
How often do the servers refresh the cached addresses? How is this time decided? Thanks!
thank you for making it simple and interesting :)
192.x.x.x is a private IP range
+BZ Yes, privae IP addresses are in DNS as well. We had to use private IP addresses since we didn't want people to start pinging and sending requests to public IP addresses and then get accused of sending people to certain IPs (yes, it has happened before).
+BZ 192.168.0.0/16 is a private range not 192.x.x.x
+DNS Made Easy Videos Use the 555 equivalent of telephone numbers for IP addresses like TVs and Movies do. 99.256.10.300
I just don't understand why the IP needs to be made of numbers instead of letters and numbers. Is this an 80's oversight?
Really great video. Entertaining and informative. Thanks!
Where are the name servers located? Is it just on some IP on the internet?What would happen if these servers were shut down or destroyed somehow?
How does the Resolving Name Server knows about the TLD at 3:29?
Good Video, thank you for explaining. Thumps up!
the most awesome video i ever seen. So much creative
Our DNS servers update as soon as any changes are made within our web control panel, propagation is instant on all global name servers. Resolving name servers provided by client's ISP's updated based on the TTL of your records. In DNS Made Easy TTL's are user defined on a per record basis and can be set as low as 5 seconds.
Fantastic video. Very well done!
@DNSMadeEasy True, and understood, but the implication in the video was that the last dot would appear when you go to a website, at the part where you said "Go ahead, try it out. We'll wait."
The IP address 192.168.1.1 is a bad example. IP addresses in the range of 192.168.x.x. can only be used in private networks. Also there isn't anything about ISP caching DNS servers. But after all a nice video. Thank you.
Also as far as I am acquainted with the subject, recursive DNS queries may lead to Distributed denial-of-service attacks, which makes them security holes. Correct me if I'm wrong, please.
3:18 - those looking for THE ROOT
nice vid..
any reason you took a local ip-adress as an example?? i mean if im not totally wrong youd never get a 192.x.x.x ip adress from a webpage right? isnt that reserved for local networks..
These politcal stabs what are they referring too exactly? Is there some proposal to fuck up the internet? Would love to know.
really very helpful in really very less time.
Good job... U can be a very good teacher because not that may people can make me understand. :) thanks
Really a great and helpful video...thumbs up
Can I use a little part of this video for a video tutorial? Obviously i will mention your channel.
really good video.....good job, hope you got more
I learn DNS from this video..
Awesome video! wicked helpful
@AutoPsychotic That end dot represents the root of the Internet's name space. Basically, it's always at the end of whatever URL you type into the address bar and is the first thing the Resolving Name Server looks for when requesting the IP Address for the site you want to visit.
awesome super easy to understand video!!
what an entertaining video on sn otherwise horrendously dry subject!! Great!
I like this guys he is funny and actually got to my head something thanks dudd tomorrow I got exam in networking I think I wont forget what I learn now :D
Seriously awesome video!
Great video, helpful and entertaining.
I feel smarter already. So let me get this straight I perform a search in the navigation bar and it goes through 4 different servers before I get a response, amazing.
I am wondering though what legislation you might be speaking of that would disrupt this process. I guess I'll have to visit your sit to find out
hello cool kid its really an awesome presentation..but we would be very pleased if u provide some more like this on different media not all with networking ,all into OS,kernels,boot loaders ,ROMs&firmware sort....thanq
Very well formulated. Enjoyed the video. Thank You!!
great video...
Keep your hands off my DNS Mr.politician sir!
wat a cool video.. i am amazed.. keep rocking man..
Hey pal I think thisis the best way to teach.Very well done thnak you :-)
I'm not gonna lie, while learning networking, DNS was the complicated thing to learn.
