500 Host

The document describes the subnetting of multiple IP address ranges to create subnets and host addresses. It provides the network configurations for routers and switches to separate a biology (Bio) lab network and physics (Phys) lab network, each connecting to a central science router at 172.16.5.1 and 192.168.5.1 respectively. Host configurations are also listed for devices on the Bio and Phys subnets.
