Set-DhcpServerv4DnsSetting is accessible with the help of DHCPServer module. To configure DHCPServer, go through this link.
Synopsis
Configures how the Dynamic Host Configuration Protocol (DHCP) server service updates the DNS server with the client-related information.
Description
The Set-DhcpServerv4DnsSetting cmdlet configures how the Dynamic Host Configuration Protocol (DHCP) server service updates the DNS server with the client-related information. This cmdlet modifies the effective DNS update setting and sets the setting on the server or the specified scope, policy or reservation.
Specify at least one parameter related to DNS update settings from the following parameters:
— DeleteDnsRROnLeaseExpiry
— DynamicUpdates
— NameProtection
— UpdateDnsRRForOlderClients
— DnsSuffix
— DisableDnsPtrRRUpdate
If you do not specify any of the ScopeId, IPAddress, or PolicyName parameters along with the parameters for DNS update settings, then the specified DNS update settings are set for the server level.
If you specify ScopeId, the DNS settings are set for the scope. If you specify PolicyName, the DNS settings are set for the server level policy. If you specify both ScopeId and PolicyName, the DNS settings are set for the scope level policy.
If you specify IPAddress, the DNS settings are set for the reservation. Do not specify IPAddress with ScopeID or PolicyName.
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.

| Position: | Named |
| Default value: | None |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-DisableDnsPtrRRUpdate
Indicates whether the DHCP server performs the dynamic DNS registration of only A records. If this value is $True, the DHCP server performs registration for only A records. If this value is $False, the server performs registration of both A and PTR records.

| Default value: | None |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-DnsSuffix
Specifies a guest DNS suffix for registering DHCP clients with the DNS server. The string must contain at least one character and cannot exceed 256 characters. Do not specify this parameter unless you specify the PolicyName parameter.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-DynamicUpdates
Specifies the conditions under which to perform dynamic updates on the DNS server. The acceptable values for this parameter are:
- Always. The DHCP server service always performs dynamic DNS registration of A and PTR records for the clients.
- Never. The DHCP server service does not perform any dynamic DNS registration
- OnClientRequest. The DHCP server service performs dynamic DNS registration of A and PTR records if the client has requested the same in the DHCP client message.
| Type: | String |
| Accepted values: | Always, Never, OnClientRequest |
| Position: | Named |
| Default value: | None |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |

| Position: | 2 |
| Default value: | None |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-NameProtection
Specifies the enabled state for the DNS name protection on the DHCP server service. If this parameter is set to True, DNS name protection is enabled. If this parameter is set to True and there is an existing DNS record matching the name, the DNS update for the client fails instead of being overwritten.
| Type: | Boolean |
| Position: | Named |
| Default value: | None |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

| Position: | 1 |
| Default value: | None |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-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.
| Type: | Int32 |
| Position: | Named |
