Just awesome.. thanks
Great explanation 👍👍
thanks a lot
Why should a resolver server go through three servers to find the IP…can’t it go directly to the authority server for that IP since the server is the final server?
I Think or May be Most of Us Here are Indians😂,, Because of stupid professor’s in India 😭😭..This man Teaches us very clearly 👍..
You just made me understand DNS in a single GO 🙂
I’m watching by my gaming computer says dns server not found. It worked thx
Thankyou beautifully explained
can anyone tell me where OpenDNS or other "non ISP" DNS services fit into all this?
But i still dk why some website cant open if i make dns auto but when i change my connection to 126.96.36.199 188.8.131.52 i can open that website.
Great explanation thank you.
Why doesnt the TLD server have the IP address of a top level domain like Yahoo.com? Isnt that a top level domain?
What’s the obstacle for resolver to ask for ip address to authoritative name server directly?
Only 650k subscribers? You deserve more!
So it won’t improve my shitty ping
God bless 🙏🙏🙏❤️❤️
Looks like the Resolver thing is in a big trouble asking addresses here and there …
Hi PowerCert, your videos are the best, easy to understand, people like you make the world better, you guys contribute more to human society than those fake, selfish, lying son of bitch politicians around the world, hahahah:) . Anyway, good work. and pls upload more videos about how to use windows operation systems or IT knowledges if it’s possible. Many thanks
Gracias x Compartir .mucho q aprender
Thank you for your video. I’m from india & want to learn about basic IT stuff. Now i learn it free thanks to you🙏♥️
Quick question – Why not go straight to the Authoritative name server straight away? Whats the the point of the Root server and TLD?
DDNS is today obsolet , does not work in Modern ISPs
you have either DSLITE or CGN
no IPV4 Address will be allocated to you
go for IPv6
Your work is really appreciable. Keep going on. : )
Then what’s use of these root servers and TLD servers when ANS knows everything?
simple thank you
Wifi router that I recommend (affiliate) https://amzn.to/2Jv577C
and the crazy part is, all this happens in like a second.
Hey there, may someone help me with my following questions:
– is the resolver the same as a Wifi Router?
– in the Video it says when I knew the IP Adress I could directly visit the website. But there are domains sharing the same IP adress… how will it work then ?
Kind regards for your answers.
super good explanation..
by the way
its not the main reason to use DNS names,
I think the main reason is, that
webserver can go to another phisical place
This is best video I have seen on DNS please upload some others topics like errors in networks, Types
What happens when the resolver stores the ip address of yahoo but the yahoo server’s ip address has been changed? How will the resolver notice that?
A quick question, (I am totally a newbie in these tech stuff ok?) why doesn’t the TLD know the IP address if it deals with the .com that yahoo is part of?
I just can’t believe how well explained these video’s are. Props to this man!
Dziekuje bardzo! CZESC.
Just wondering, why does the resolver use the root or TLD servers, and not directly to the Authoritative Name Server?
Why have a root server or TLD if those servers don’t know the IP address?
From high levels to details , the essence pedagogy of wisdom . Thank you.
Awesome explanation. Thank you very much.
the best place to learn tech thing in easy way love this channel
If anyone manages a subdomain of a TLD (like example.com), you already know how the DNS works in deeper details. There are multiple types of DNS records and it’s up to the domain admin to manage those records and keep them up to date (as well as keep the domain active). There are A records that point a subdomain of managed domain (or the root of the domain) directly into a specific IP address, CNAME records that point the same thing into another domain, which then resolves to IP address in final step, SRV records that instead of poiting domain to an IP address or another domain, it actually sets up specific applications for a specific port to be accustomed to the managed domain (which has to be manually filled in), and finally MX records that are used for e-mail handling so POP, IMAP and SMTP servers could reach the said domain. Don’t forget that DNS records have to be configured properly as inproper configuration may lead to domain malfunction and your websites or online service simply won’t work. I manage domain for our Minecraft server, and we have multiple of services up and running, including websites and e-mail service of course, and of course Minecraft network (BungeeCord) and a TeamSpeak service so players can hang out and talk with admins and mods. Discord isn’t listed there as their services are not open-source and Discord runs strictly through their own domain. It’s so easy to screw things over and then it’s so hard to identify the problem because all it takes is one mistake to make the whole system just break.
