In the last post we covered tasks related to IP address space that abstract the actual infrastructure like services and servers. In this post we will go a little deeper and see tasks related to services like DHCP and servers that host them. You can find the submenus which we will use under Monitor and Manage.
We will be looking at the first 3 menu items. From the last one you can configure the servers to be shown in groups based on different criteria. The first submenu you can see is DNS and DHCP Servers from where you will be able to configure settings related to the actual DNS and DHCP servers. In the next 2 submenus you will see your DNS zones and DHCP scopes and will be able to change settings and do different tasks.
IPAM tasks related to DNS and DHCP servers
After you click on the first submenu you will see a list of both DNS and DHCP servers along with some info about their state, time elapsed while in that state and more.
In case you want to see only DHCP servers for example just choose this option from the Server Type drop down. When only DHCP servers are selected you will have the option to choose different information that can be viewed by selecting it from the View drop down menu.
If you right click on one o the servers you will be able to see the options available. We can edit the DHCP server properties, add/delete DHCP server wide options, create a scope, add new user/vendor classes, launch the DHCP MMC connected to that server and more.
Server properties which can be edited are related to DNS Dynamic Updates, DNS Credentials for dynamic updates and also MAC Filters as you can see from the image below.
Adding or removing DHCP server wide options is very easy from the IPAM interface. Here is a screenshot with the dialog box for this task:
You can see a lot of info about the servers or services highlighted in the Details View. Here is an example of information about a DHCP server.
If you right click on a DNS server you will observer that the options are a little slimmer. We can open a DNS MMC, create a zone and create forwarders. Not too much to talk about here.
We can create a zone very easily from IPAM by just selecting the option on a speciic DNS server and completing the info like zoe name, type, category, where to store it and more.
IPAM tasks related to DHCP scopes
Let’s head over to the DHCP Scopes submenu. Here, of course, we will see a list of our DHCP scopes and some info about them like lease duration, prefix length, percent occupied and more.
Tasks that we can perform on scopes is edit them, duplicate them, create reservations, configure scopes for failover, deactivate them and more.
If you want to create a DHCP reservation it is very simple: just enter a name for it, an IP address and the MAC address of the client which will get the IP. DNS Dynamic Updats should be set to Yes if you want the client to have a DNS entry generated.
And here is how it looks in the DHCP console:
Reservations can also be viewed from the DHCP Scopes pane by setting Current View to Reservations. The one we created is Inactive because the MAC address that I used does not correspond to any of my clients.
IPAM tasks related to DNS zones
The last part we will cover in this post is the DNS Zones submenu. The info we see by default is a list of all forward lookup zones from the managed DNS servers with some information about them like Status, Primary Server and more. There are not a lot of tasks possible for DNS zoes as you can see:
Probably one of the most usual tasks you do regarding DNS is to add records. From IPAM you can do this really easy. Just select your zone and open the Add DNS resource record wizard. Select the resource type, specify the name, IP address and if a PTR record should be created in the reverse lookup zone. Add it to the list and finish the wizard.
And here it is in the DNS MMC console:
I advize you to try the features out for yourself in your test environment to get a real feel for the IPAM console.
