How to create and delete a DHCP reservation in Windows Server 2019

Sometimes you may need to reserve an IP address for a workstation or a device from your DHCP pool. Administrators can easily configure a DHCP reservation in their DHCP server when they need to reserve a permanent IP address. A DHCP reservation is a permanent IP address assignment. It is a specific IP address within a DHCP scope that is permanently reserved for leased use to a specific DHCP client. For more on DHCP Console Icons Reference.

Reservations are used for DHCP enabled devices like print and file servers or other application servers that always have the fixed IP address on the network. A reservation consists of the following information.
