Thought I’d share a nice wrapper for netsh and dnscmd calls to allow easy, bulk provisioning of new DHCP scopes. It’s nice being able to provision a ton of these at once by piping the output from Import-CSV!

    host the lower scope portion. Upper/Lower 'tags' are added to the description when using
    the Split50 switch.
