Description
The Add-DnsServerRecursionScope cmdlet adds a recursion scope on a Domain Name System (DNS) server. Recursion scopes are unique instances of a group of settings that control recursion on a DNS server. A recursion scope contains a list of forwarders and specifies whether recursion is enabled. A DNS server can have many recursion scopes.
DNS server recursion policies allow you to choose a recursion scope for a set of queries. If the DNS server is not authoritative for certain queries, DNS server recursion policies allow you to control how to resolve those queries. You can specify which forwarders to use and whether to use recursion.
The legacy recursion setting and list of forwarders are now referred as the default recursion scope. You cannot add or remove the default recursion scope, identified by name as dot (.).
Examples
Example 1: Add a recursion scope
PS C:\> Add-DnsServerRecursionScope -Name "ScopeInternal" -Forwarder 10.0.0.1,172.22.0.1 -EnableRecursion $True -PassThru
Name Forwarder EnableRecursion
---- --------- ---------------
ScopeInternal {10.0.0.1, 172.22.0.1} True
This command adds a recursion scope to the DNS server. This scope enables recursion and specifies two forwarders.
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.

-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

-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.
