You have expanded your current lan from about 200 hosts to over 350 hosts. the first 200 hosts were getting ip addresses from a scope configured with the address range 10.1.1.1 to 10.1.1.250 with prefix length 24. you don't want to change the ip addressing scheme for the existing hosts, but you need to accommodate all 350 hosts with dhcp-assigned addresses. you don't have any vlans or routers configured. what should you configure?

You should configure a DHCP superscope.

Explanation:

The problem here is that after the host #200 is connected to your LAN, the next host IP is going to be the APIPA Address(Automatic Private Internet Protocol Addressing) because the server don´t have any IP to offer, in windows server you must configure a feature of the DHCP service called superscope. A superscope is a feature of Windows Server DHCP that enables to serve multiple IP subnets to the same physical LAN, this feature will enable another subnet in your system so any host connected must have a valid IP address.

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
