This command allows you to get the DNS Server address that has been assigned to the specific Network Interface.

PS C:\WINDOWS\system32> Get-DnsClientServerAddress -InterfaceAlias "Wi-Fi"
 InterfaceAlias               Interface Address ServerAddresses
                              Index     Family
 --------------               --------- ------- ---------------
