DHCP: How to work with user classes on Windows
Whether in an existing network or a new one, there is an aspect of design that cannot be skipped: deciding if handing out IP addresses will be dynamic (automatic) or manual (one-by-one) or—the most common—a combination of the two.
By choosing to distribute them dynamically you are choosing to use a dynamic host configuration protocol (DHCP) service somewhere on your network, and there can be some tricks to that regardless of what server you use. For this discussion, I will describe how to use user classes on a Windows DCHP Server to specify a range of IP addresses and to assign range-specific DHCP options.
