I'm not a "developer" and I learned DNS without any problems. Therefore agree with other commenter that DNS is not actually difficult to learn. I like the output from DNS utilities such as BIND and tinydns format.
DNS is worth learning for any internet user, IMHO. I've written primitive utilities that when used together can do stuff none of the popular DNS utilities can do. I use these every day.
Here's DNS challenge for readers. Try to look up the domain "bootable.com". Use whatever is the preferred method.
People writing about DNS often compare it to a telephone book. IMO the way most people use DNS is more like "directory assistance".
IP addresses do change but by and large most stay the same for long periods. Old zone files, publicly available scans^1 and other bulk DNS data collected from web crawls and public DNS caches comprise the "phone book" for me. Absolutely essential.
1. Sadly, in recent some of these sources have changed to non-public. No phone book for you! Call directory assistance.
