## SETTING UP DHCP

{% hint style="info" %}

#### WHAT IS DHCP?

Microsoft Windows Server operating systems includes Dynamic Host Configuration Protocol (**DHCP**), which is an optional networking server role that you can deploy on your network to lease IP addresses and other information to DHCP clients. All Microsoft Windows client operating systems include the DHCP client as part of TCP/IP, and it's enabled by default.

Read more about Dynamic Host Configuration Protocol [here](https://docs.microsoft.com/en-us/windows-server/networking/technologies/dhcp/dhcp-top)

After installing the Active Directory server role on my DC server, it's time to install and configure the DHCP server role, so log into the DC server again, and we will start setting up the DHCP server role for my LAB environment.

{% hint style="warning" %}
Give it a subnet mask and a range of address from the private IP range we created in [Part 2](https://www.osdsune.com/home/blog/2020/configmgr-lab/part-2#hyper-v-nat-virtual-switch) during the Hyper-V configuration.
{% endhint %}

The Router (**Default Gateway**) IP address is the IP address of the Virtual NIC that we created in [Part 2](https://www.osdsune.com/home/blog/2020/configmgr-lab/part-2#hyper-v-nat-virtual-switch) during the Hyper-V configuration.
{% endhint %}
