Learn how to create a primary forward lookup zone. This will make a DNS server authoritative over a selected area of namespace.
- [Instructor] One of the most important components to a DNS server is the presence of a DNS zone. Now what is a DNS zone? Well, essentially it's a database of DNS records and it's these records that allow us to do the actual name resolution and when a DNS server hosts a DNS zone, that makes it what's called authoritative over the name space that that zone has records for. So there's a number of different zones that we can create and what I want to do here is show you how to create a Primary Forward Lookup Zone and to do this we're going to jump onto Member one which is a member server in my domain where we've installed the DNS server role.
Here in the server manager, we're just going to go up to the Tools menu and select DNS and this will take us into the DNS Manager. Now you'll notice when we're highlighted on Forward Lookup Zones, it's just blank, it just says we need to add a new zone so to do this I'm going to right+click on Forward Lookup Zones and select New Zone. This takes us into the New Zone Wizard. Here's the Welcome screen, I will click Next. I need to determine what type of zone. Actually there's different zones, Primary, Secondary's or Stub.
In this case I want to create a Primary which means it is essentially a master copy where updates can be made directly on this server. I'll click Next. We need to give it a name. The name I'm going to choose here is going to be child dot landonhotel dot local so we're essentially going to pretend, right, we already have our landonhotel dot local, we're going to pretend that we have a child domain that we've created and we called it child dot landonhotel dot local. Now we'll click Next. Now I need to either use an existing database file if one exists, very rare that you would do that, more typically you will create a new file and it gives you a default name which completely makes sense, it's the name of the zone dot DNS so we're going to leave that alone and just click Next.
Now you need to determine how updates can be made to this particular server. We can either, the default here is to not allow dynamic updates which means you'd have to manually come in and update the records or we can do dynamic updates which is it says here allow both non-secure and secure which is a little bit dangerous because with non-secure it means people can get in and hack into this database. There is another option. It's up at the top, it's grayed out, which is for secure dynamic updates only but you have to be a certain type of zone which we will talk about later.
It's called Active Directory Integrated Zones. So for now I'm going to say Allow Updates even though it's not secure. Now click Next and Finish and just like that you can now see that inside Forward Lookup Zones we have a zone, okay. And if I expand it there, I can click on it, you see we get a couple of records that show up. We'll talk about records later but that's how you create a Primary Forward Lookup Zone.
