I don't know if this issue existed previously
1. Start PowerShell or PowerShell ISE in Windows Server 2012.
2. Type: get-help new-netipaddress -detailed to view that one can specify -DefaultGateway
3. Type: get-help set-netipaddress -detailed to view that one cannot specify -DefaultGateway
I expected to be able to specify the default gateway for an IPv4 address using the Set-NetIPAddress command.
