Configure DHCP Scopes In Windows Server 2016

After installing DHCP server role in Windows Server 2016, the first step in configuring DHCP would be creating scope. I will show you how to configure DHCP scope in step by step process.

Note

Read my previous article to learn the installation process of DHCP server role.

Important Steps

Following are the 3 important steps in configuring DHCP scopes in Windows Server 2016.

1. Create New Scope
2. Configure Scope
3. Activate Scope.

Once you have successfully installed edDHCP server role in Windows Server 2016 including all the required management tools, you can open Server Manager and go to —> Tools —> Click on “DHCP”. .

Once you click on “ DHCP “, You should be able to see the DCHP Server Manager ( See below ). Here, Ind-dns1 is my windows server 2016 name, and I’m configuring DHCP Scopes on this server. Well, if I expand this server, as we can see I have IPv4 and IPv6  ready to manage….well, I am not going to manage IPv6 , I will only show you how to manage IPv4 in this article. As I mentioned above, the first step in configuring DHCP scopes is

“Creating New Scope”

Creating New Scope

To Create New Scope, right click on Server —> New Scope.

OR

Select Server —> Click on More Actions —> New Scope. ( See below screenshot )

Scope

Here, scope is the range of the IP addresses assigned to computers requesting a dynamic IP address. We must create and configure a Scope before dynamic IP addresses can be assigned.

It will open New Scope Wizard… Click —> Next

Configure Scope

Scope Name

Provide a meaningful name to your scope to identify easily.. I’ve give my DHCP scope name as “MyCompanyClients” .

After providing a description to your DHCP scope, you’ll see a IPAddress Range screen where you need to provide the Start and End IP address ( range of the scope ) and also the Subnet Mask and its length..

I specified the Start IP address: 10.4.77.220

and End IP address : 10.4.77.230 . ( For my 10 client computers )

You can also specify the exclusions of the IP addresses….As you can see in the below screenshot, I want to exclude IP address 10.4.77.224 / 225 and 226 from this scope.. So I entered the Start and End IP addresses in the Exclusions.. These IP addresses are not going to be distributed by the DHCP server..

Once you Add Start and End IP addresses in this exclusions wizard.. Click —> Add.

Now click —> Next to specify the Lease Duration ( Default lease duration is 8 Days ). I am not changing it,

Note

Read my previous article “DHCP overview” , in case if you don’t know DHCP Lease generation and renew process]

Now click —> Next —> It will ask you to configure DHCP options, but I want to configure DHCP options later, so I click on “No” and —> Next.

That’s it. We have successfully created DHCP scope with IP address range and exclusions. Now you can see in the below screenshot, If I expand IPv4, I see the Scope I created ( “MyCompanyClients”).

If I expand this scope, I will see the IP address range that is ready for distribution and also the excluded IP address range. ( See below Screenshot ).

You may notice in the above screenshot, there’s blue tick mark on IPv4 and red mark on Scope, which indicates our scope is just created but not activated…So we need to Activate the scope after creating it…

Activate Scope

To activate scope —> Right Click on Scope —> Activate..

Once you activate the scope, you will not see the blue and red tick marks.. That means the Scope has been activated successfully.
