“It maps urls to an ip address” bros been coding so much he’s using JS terminology in his English now.
ICAN: we are non profit organization

YOU ALWAYS TALK TO THE POINT. AMAZING AND TIME SAVING
Genuine question. Why do we need 3 servers for it?
so much info in 100s.
better than explaination than the shitty guy at bits and byte of networking course.
Great video for people who have previously learned computer networking but need a refresher on certain parts.
Sorry i got confused when It comes to DNS! I cant understand 😭😭
Most requests aren’t recursive!
I have learnt a lot of new things that I have never worked with from your videos, like AWS, nginx, kubernetes, graphQL(and other dbs), typescript to name a few. One thing that I don't understand is how they work together. I would really love to see a video where you design a mock system using all of these (and possibly more) and explain each of their roles and why you chose it (kinda like your reverse-cloud migration video using raspberry pi).
Whenever I think of a software architecture I think of them as several layers that interact with each other. However, I am unable to assign which layer what belongs to by watching a stand alone tutorial about a single tool.
Btw, I am a college senior pursuing CS major and I love your content. Thanks for all the awesome contents.
Additionally the TXT records are used for email security (SPF, DKIM, DMARC records).
Now, to answer the "What happens when you enter a URL into a web browser" interview question with this and see them stop me before getting to the TCP handshake part.
