I go into my command prompt, I simply type that, hit enter, and it’s going to rush through my name, and my IP address in DNS. The first one is called Ipconfig /registerdns. If I’m running a Microsoft operating system, a Microsoft operating system has two different utilities if I want to do it manually, if I don’t want to have the client do it. I have to do nothing whatsoever.Īn IP address changes, the name changes, a new machine, or a new name, whatever, it’s automatically registered in DNS. When I’m looking at this, from the client side registration, automatic means I have to do absolutely nothing. If I restart the machine, that background refresh, or I change its name, or I change its IP address, DNS is going to be automatically updated. Routinely, it’s going to go out to the DNS servers, “Hey, DNS, my name hasn’t changed, my IP address hasn’t changed,” just to make sure the record keeps updated. What will happen is, when this machine turns on, or anytime this machine gets a new IP address, it’s going to register its name and IP address with DNS. If I’m running on UNIX, Linux or Red Hat, I have the ability to configure those DNS clients as a dynamic DNS client. If I do not have a DNS suffix, I won’t know who to register it with.

Microsoft operating systems by default, since Windows 2000, has been configured to automatically register its IP address with its DNS server, that it has a DNS suffix. The DNS client has to understand what dynamic updates are. I have to configure dynamic updates, then I’ll reset a DNS client. When I get into the interface here in a few seconds in the demo, I’ll discuss that in a little more detail. Microsoft has both secured and unsecured dynamic updates. I had to tell this zone that it has to accept dynamic updates. I’ll create my zone database, whether it be a forward or a reverse lookup zone. What does this dynamic DNS allow us to do?įirst of all, here’s my DNS server. You’ll see this abbreviated DDNS for Dynamic DNS. BIND introduced the ability to do dynamic DNS. Starting back in the Windows 2000 operating system, or with BIND ‑‑ BIND stands for Berkeley Internet Name Domain standard. We don’t want to spend our time doing that unless you want that as your job security.

One or two changes is not a big deal, but what if you have 1,000 plus machines in your environment? You might be spending every single day, day‑in and day‑out, doing nothing but managing records in DNS. Nobody in the environment is going to be able to resolve to this new server, until I manually create that record in DNS. Or what if we add a new server to our environment, SVR‑2.USSHQ.Local, with an IP address of 172.16.0.120? That record gets synchronized out to any secondaries we might have in our environment. What if the IP address changes, say goes from 100 to 101, if I have static‑based DNS, I have to go into my DNS server, and I have to change that record from 100 to 101. The IP address of that machine was 172.16.0.100. One of the things we had a challenge with in static was, let’s say I had a computer called SPR‑1.USSHQ.Local. We have the ability to create records statically, or to be able to create records dynamically. Now that we’ve installed DNS, we’ve created our DNS zones, the next step is now, how do we produce those records in our DNS database?
