The server you have set up with the DHCP role, most likely have two or more network adapters. By default, all adapters configured with a private static IP can be used to respond to DHCP requests from clients. For this reason, adapters won’t appear in the list unless they have a static IP configured.
You can choose which network adapters will support the DHCP server through the Server Bindings found in the DHCP console. In the steps below, you will see how to add or remove DHCP server bindings with network adapters.

Open the DHCP Admin Console, right-click the DHCP server you want to configure, and then click Add / Remove Bindings.
In the new window, choose which of the network adapters will be used by the DHCP server for both IPv4 and IPv6 addresses.
Finally, click OK to save your changes.
