Fun fact: Amazon's Route53 service is named as such because "53" is the default port for DNS.

Can you do one on DHCP

I studied this when i did windows 2003 server, it really went in depth. to the point you can write your own cheques
@mikefinn2101 Says:
Great well done simple explanation of DNS Love your channel wish I knew as much as you or was a smart as you but your very kind to explain this. Few are so nice your a rare teacher super thanks
@pauld7827 Says:
I have always explained to people that DNS is like a phone book also!
@felderup Says:
i'd like to be able to use a router for a bit more than simple dns... i want to redirect normally unrecognised tld's to proxies that know what to do with them. i'll be building it of pi, it's something that can be added to pihole, it's not that intensive but some of the services i want to use don't allow proxying.
@davepickering997 Says:
Thank you, very well explained. So now you know why support desks insist on clearing the cache even though the process is not easy or clear (and hidden). It can be done from a command line but.... Your average user will not have the skills and worry that the rest of their stored data will be lost.

Whenever I try to install jailbreaking software I face the issue of net framework not been able to support the software. Please help me what should I do

Running an email server from the home is a tricky thing to do, fun but not great as well!

@DMP413 Says:
I have a random question:
M.2 ssd form factors. Is NVME only m key or do they make b+m keys that are NVME. Also are some m keys sata?

very helpful video. thank you!

Excellent video ...My second job is web hosting / stream broadcasting 😊
@Sir_Uncle_Ned Says:
Could you do a video on Border Gateway Protocol (BGP)
@fram1111 Says:
Even if you know well you're about to explain you give it a special pizzazz in a touch of you're own. To give us especial look at the world of DNS.
Well that's it for now until next time! Another great video for the archives.
Decades from now I predict your YouTube channel we become the most used educational tool did teach history of computer science.
@sirdaemon5338 Says:
Really good video thanks
@kueifengtung2693 Says:
This was fun, please more on dns records :)
@k-c Says:
Nobody else explained this better to me than you. Thank you!!!
@Cjx0r Says:
Inference vs Prediction video when?
@Croaker369 Says:
I’m confused. Why doesn’t the Auth Name Svr send an ip address instead of a email address???
@srvuk Says:
A tough one to get across in a complete manner.
@ElmerFuddGun Says:
Chris, your end of video links are missing. Oops!
@jacobofraiz Says:
Great divulgation video. Thank you.
@ArniesTech Says:
I am afraid, my DNS resolver isn't proud about my request history and what it holds in cache 😮

Thank you Chris! Very informative!

Hi Chris, very informative. Thoroughly enjoyed it 👌
@ecu4321 Says:
Whatsmydns is a good dns verifier for various types of records
@PaulRansonArt Says:
Brilliant video of course Christopher. A little off topic for this video - have you herd of Ventoy? Its open source software used to create a multi boot drive for trying out different Linux distro's. Looks interesting so though I'd drop you a comment.
@innerfinder100 Says:
Thank you the next video should be how to setup your oun server in a SBC
@AllensTrains Says:
You might like to make a video explaining how to set up a DNS and web server on a Raspberry PI, as some people in their bedrooms would not be able to pay a subscription! Thanks for uploading.
@chriholt Says:
Thank you Chris (as always). I have had to learn all of these gory details as "on the job training" which I don't regret at all, but it is great to see these explained so clearly!
@procactus9109 Says:
It would have been good to hear about DNSs weakness and how it can be used against us
@DrinkToYourHealthForLife Says:
DNS? Don't get me started. It is 2023 after all.
@silverback3633 Says:
Thanks for explaining that a layman like me can grasp an inkling of how it works. You are truly an Explaining Computers.
My uncle was a postmaster in the mid-century when telephone and telegraph systems were integrated. Having played with the telephone switching console to the Morse code keyer, I am still wondering about all the protocols from sending registered mail to sending and receiving telegraphs, and how they all worked.
Next may be how the internet search works.
@4ryan42 Says:
Shoutout to everyone running their own DNS resolver at home on a raspberry pi (Pi-Hole here).
@privacyvalued4134 Says:
The one thing you didn't cover is backups. Backing up DNS records is something that few people think about doing. If you have a simple setup of one domain and a handful of records, it's probably not too difficult to restore in the event of any issues arising. However, even small businesses have hundreds or even thousands of DNS records and a company like Microsoft maintains a portfolio of tens of thousands of domains and hundreds of thousands of DNS records. Backing up DNS records becomes more essential/mission critical as more records get added for various purposes. Backing up web servers is its own separate topic too.
@privacyvalued4134 Says:
Hosting your own website is a lot of work. It's not for everyone. However, shared hosting has tons of limitations and ultimately costs about the same per month as a good cheap VPS solution. The general rule of thumb though with regards to website hosting is to not put all your eggs in one basket. That is, the domain registrar should always be separate from the hosting provider. So many horror stories exist of people who bundled everything and wound up in a situation where they lost everything.
@michaelwright2986 Says:
Getting things that clear takes a special talent and a lot of work.
@joeg3950 Says:
Thank you for the video. I just started my own website and had a crash course in some of these topics. Very helpful video.
@iPondR Says:
So happy to be a channel member!! This is a topic I've wanted to know about... but didn't know it! Thanks! :D
@HyperspaceQ Says:
Stellar, Christopher!
@GrantSR Says:
I have used DirectNIC for decades. The things i like best about them is A) No BS, and B) They have very thorough and understandable documentation about all of this. Even if you don't use them as a registrar, it's worth taking a look at their documentation.
@MichelMorinMontreal Says:
A new masterclass to help you understand everything about DNS in 12 minutes! It's got to be done! And it's done! A video to be circulated among geeks and digital students alike. Personally, I learned a lot, so thank you very much.
@jaffarbh Says:
Gone the days when organisations (including SMEs) used to host their own Exchange server and Active Directory on prem and thus internal DNS servers :)
@Chris.Brisson Says:
I've always wondered why my router, which dolls out IP addresses to clients on my LAN, has trouble resolving the names of the clients (many of them listed with a Host Name of "Unknown". Why doesn't a router use a hosts file that I can edit. I'm thinking it is not a good thing to have so many mystery clients attached to my network.
@DoctorOnkelap Says:
Lies, you left out all the magical gnomes and fairies inside all those 'servers' that do all the actual work and also read the minds of the end users so they know what they want!
@watsoft70 Says:
Spent years in IT and still learning! Thanks Christopher for enlightening someone that appreciated what goes on, but never worried about the mechanics of it. 👍🏻
@adunford2664 Says:
Very well explained video. Are you able to do a similar one on home Wi-Fi routers and the latest standards?
@dankierson Says:
Short and sweet.
It might have been useful to also outline the various data kept on domain owners and the visibility of such data to the Internet public.
Email deserves a video of its own - as does the 3 DNS records needed for smooth transmission of email.
One topic really needing a comprehensive video is how to set up your own email server on a VPS, interface it with both a mail delivery agent (plus mail user agent or email client) and a webmail server.
Oh to be independent 😊
