Get-DhcpServerv4Reservation is accessible with the help of DHCPServer module. To configure DHCPServer, go through this link.
Synopsis
Gets one or more IPv4 reservations for the specified IP addresses or client identifiers (IDs).
Description
The Get-DhcpServerv4Reservation cmdlet gets one or more IPv4 reservations for the specified IP addresses or client identifiers (IDs). If only the ScopeId parameter is specified, then all of the IPv4 reservations from the specified scope are returned.
Parameters
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell background jobs, see about_Jobs.

| Accept pipeline input: | True (ByPropertyName) |
| Accept wildcard characters: | False |
-ComputerName
Specifies the DNS name, or IPv4 or IPv6 address, of the target computer that runs the Dynamic Host Configuration Protocol (DHCP) server service.

-ThrottleLimit
Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
