Question

CSM Tech Publishing has expanded its network from one subnet to two subnets and is putting 200 computers on the new subnet with plans for adding up to 100 more computers over the next few years. Currently, it's using DHCP for the existing subnet and has a scope configured with start address 172.16.1.1 and end address 172.16.1.200 with a prefix length of 24. The DHCP server is in the main distribution facility where the router is placed to route between the subnets. The current DHCP server runs Windows Server 2016, is performing well, and has plenty of unused computing resources (CPU, memory, and so forth). You need to configure DHCP for the new subnet at the lowest cost possible. What do you recommend for adding DHCP services to the new subnet? Propose a DHCP configuration, the scope's start and end addresses, and the prefix length for the new subnet. Please write a short report.

Answer 1

To achieve reduced DHCP configuration costs you need to automatic assign IP address assignment at each remote site substantially it will reduce Internet access costs. DHCP offers centralized management. The DHCP Server can be used to maintain configurations for several subnets, hence an administrator only needs to update a single, central server when configuration parameters change.
To add DHCP services to the new subnet you need to first configure the DHCP Server features like identify an external File Transport Protocol (FTP) or a Trivial File Transfer Protocol (TFTP), or remote a copy protocol (RPC) server that you will use for storing the DHCP bindings database. Second identify the IP addresses that you are to enable the DHCP Server assign, and the IP addresses that you will exclude and then configure them as required. Third identify the DHCP options for devices where necessary including the following: default routers, Domain Name System (DNS) servers and decide on a DNS domain name, default boot image name, decide on a NetBIOS node type and the NetBIOS name server. Since there is an already existing configuration it will require updating and choosing what to retain and what to change.
In this case since the DHCP Windows Server 2012 has enough resources it is advisable to continue using it for the two subnets. Since it is possible to use secondary IP addresses on the routers and access servers that allows you to have two logical subnets using one physical subnet. There is need for a new subnet to hold at least 200 computers. The proposed subnet can have a scope configured with start address 172.16.2.1 and end address 172.16.2.300 with a prefix length of 24.
