Is there any proper book that can teach about DNS? I'd like to set a fucking proper DNS Server for once using BIND9, but I'd like to learn everything about it first.
Which resources did you use to learn it fully?

Thats awesome, no other resource/book can compare to the source itself, thanks
dns will make you absolutely no money. good luck!
yes and no. dns concepts are integral in network engineering for several specialties. mid and top level network engineers can make a very good living.
Good luck being replaced by a cloud platform.
It's actually very important to know DNS in the cloud because something WILL break and literally nobody will have any clue how to fix it because the just know how to click buttons in AWS instead of the actual underpinnings.
>t. fixes DNS-related tickets weekly in cloud environments
like i said, dns alone won't get you shit. dns itself is the simplest thing ever, there's nothing to learn. dns is one of the services you'll spend almost zero time getting to know. also, i haven't hosted by own dns in like 20 years. why? no point. now its just cnames and a records. dns is stupid easy. stop "trying to learn" things that are simple, stop overthinking

When you need to program a piece of software that simultaneously streams multiple videos being either fed in by major broadcasting companies and/or video recordings over multi-cast channels, and you need to provide the user the ability to switch between them. Then yes, knowing DNS will make you money. Will DNS by itself make you money? No, but knowing how to manage networks will.
Not by itself, but like someone else said, knowing deep DNS will make IT life much easier
I was actually paid to work on it by itself. If I hadn't lost my mind I probably could have stayed for a while.
Focus on setting up
> Forwarders
> Dynamic DNS
> Split Horizon
> DNSSEC
Probably in that order. Godspeed.
Implemented a stub resolver in python
i'd rather learn about that grasshopper than learn about DNS
Based!
so i decided to learn about this big nigga, since i've seen them around before. it's the biggest grasshopper in north america, it's called the eastern lubber. when threatened, it will hiss, puke, and coom a smelly froth onto you.
So basically the average anon in grasshopper form? Cool

What's a resource that explains rDNS and PTR records the most comprehensively, like how they are used, queries and answered and how they work on netblocks?
Id like to know too
I used to manage servers for a web host. Mention of PTR records make me want to kms
The book in your image taught me how to build my own Bind servers at home and I was also able to comfortably use the ones we run at work.
