DNS, IP Addresses & Ports - Rest APIs In Depth

I am 48 years old trying to change my profession. It seems that this course finally opened my old brain and let it absorb the tricky knowledge

I would absolutely love some network programming in c content. It’s a topic I am very curious about. I’ve never written any c but I am going to start learning and writing it as a academic language and for a web dev I think network programming would be the most useful.

Hey Mike! I couldn't agree more, in fact I thought of doing this course in C. However I wanted to reach more people coming in to web dev from the front-end too for the first time. I'm following most of the roadmap path I have for new devs to get in to the field of web dev. That said, I would absolutely love to make some of the lower-level content later in C where we can really see the internals, similar to what you'd do in Computer Science. Let me know if you have any other such ideas for videos, love it! 🤓

@@TechWithNadersame idea but with Rust instead 😂

DNS allows us to group multiple IP's to a single domain name. Which is also very useful for globally distributed systems like google that have many different servers across the world. Also public IP's aren't static meaning that you would have to look up the IP for google every time it changes to a new IP but with DNS we can automatically get a reference to the most recent IP through the DNS lookup. Though with google their domain name is likely tied to a Load Balancer to distribute to other Load Balancers based on geolocation.

Very nice answer! You hit on most of the main points, spot on! This becomes much more apparently when you buy your own domain too and have to configure name servers and ip addresses for things. I wonder how often the ip for the main load balancer for Google changes 🤔

thank you Nader

Maybe your query arg is not working with nslookup because it's supposed to be a flag? -query=A (according to IBM docs)

Thanks Claire, that's it! Always fun when different CLI tools do things with the '-' or without! Nice catch 🥳
