I didn't have much idea about the IP address and related info, now I got it! Your videos are very easy to understand, keep on posting these kinds of interesting videos!!
Absolutely amazing series. You explain the topics in great detail and with perfect examples. The visualization also helps so much, a lot of videos talk about HTTP and WWW and DNS but this is the first time I've seen someone show visual and live examples. You have done an incredible job!
Excuse me (and pardon me for my English) the thing that iam thinking that it is wrong : every 4 octet of the ip adress should be from 0 to 255 but why and how its more than 255 ?
Why do you use invalid IPv4 addresses in the examples? They are supposed to be composed of 4 integers between [0..256), because that's the range of possible values of a byte. 32 bits is 4 bytes. 12.34.567.90 is a completely invalid IP address for example (example from the video).
I see you're using mathematical notation. The semi-open interval [0...256) would normally include 255.7, for example. "0 through 255," in plain English would be a better option to express what you mean. But you're correct, I don't understand why he's using invalid IP addresses. At one point, he even uses one with five numbers.
Yeah, someone else made that same comment and you're right. Values cap at 255. Just an oversight in typing the slides and the concepts here a high-level..
Is it possible to remove the IP address from the system and identify the server through the domain name? Domain names are unique. So, why can't we keep the server name same as the website domain name?? Whenever the company doesn't want the service, we can rename the server. I know this will be tedious but can we do it?

Glad you like them!
@@FollowAndrew very true these are delivered in a very simple way as well love your way of explaining stuff
You just made it so simple for me thanks so much. The DNS is the same as the IP address one is numbers the other on is actually words/lettering.

Thanks, will do!
Very nicely explained. Thank you 🌍
this was a very great video
Your videos are amazing! Keep doing more videos, thanks!
Thanks for this information ❤
Very good lessons, keep them up :)
For clarity... DNS = Domain Name System... Saying "DNS Server" is equivalent to saying "Domain Name System Server".
great explanation, very helpful.
Nice work, thanks for sharing
Andrew Thank so much! You're really amazing! I really enjoyed!
Yes I repeat, you are the best
Thanks
Wow, this is interesting!!!
wow That's really amazing
Great video, very good!!
I think there is a little mistake in 2:21, where fourth octec is 890 , maybe you meant 89 ?
This is worth watching

It's because computers can't understand that. They operate on low level and only understand 0's and 1's.
Andrew, you are the best:)
Just subscribed to your channel! Much to learn
Welcome aboard!
