- [Voiceover] The prerequisites for this course are a little higher than usual for a course that I might teach. And that's just because I'm going to go into some stuff, in the DNS course that I can't teach from the ground up. I can't teach a lot of this stuff to you if you have absolutely no prior experience with computers right. So, there are some basics that you kinda have to know. But I think if you are coming to this course in the first place, you probably are going to be fine because, folks who don't know this stuff, probably wouldn't be looking for a DNS management essential training course.
Let's see what we got. So, prerequisites for the course include, an understanding of IP addressing. You don't have to fully understand IPV6 addressing and how that works, that's fairly new in the world and we'll only talk about it briefly, but IPV4 addressing and subnets and routers and what those things are, at least knowing what they are is a really really good idea. You may not need to know the full networking multi-layered thing, but if you understand what at least these things are, that's very helpful. You should have experience with the internet.
I mean this is pretty obvious, right? If you've never been to a web page before then I don't know how you're watching this video. So, experience with the internet, super important. DNS is extremely important to the internet and the way we talk about the internet implies that you've been surfing the internet for a while and you know what you're doing, and that you send email and that you set settings on things like calendar applications and stuff that use the names of servers instead of their IP addresses or even their IP addresses, whatever, but experience with that is useful. Also, and this kinda goes with what I said before, currently, you probably should be employed in an IT-related field somehow.
Whether that be as a consultant, or as an enterprise level desktop support technician who wants to become a DNS administrator someday or something like that right. If you're coming to this from the perspective of someone who's never worked or imagined they might work in an IT related field, you might find that you're a little lost. Or, you know, you could be somebody who just plans on entering into an IT-related field and if you are that person I welcome you. That is awesome. But again, have some basic experience with the internet and know what IP addresses are and know what a Subnet mask is.
There are other courses here on lynda.com that go into basics of networking that would be great prerequisites for this course. Okay, I need you to be really willing to learn and to go back and review. There are some pretty deep concepts here. I do go back and review things within movies. I would go back over and over again and talk about the same things in different contexts to help you to learn this stuff but, you may find yourself scrubbing back in movies and watching them over again, just to get a fundamental understanding of what's going on and that's fine.
Just understand that that's probably going to be necessary at some point during this course. And then, there will be course assessments here and I would highly recommend that you take part in those course assessments as they are designed to help you to understand what's going on here and to help you to test yourself on whether or not you are catching the important concepts as we go through the course.
To begin, author Sean Colins covers the fundamentals of DNS. He then segues to more complex topics such as setting up a DNS server on Linux, Mac, and Windows and working with DNS record types, such as AAAA, MX, TX, CNAME, and SPF. He offers breakdowns of difficult concepts as well as practical technical tips for the day-to-day activities involved in DNS server management.
