Overview
Module: Network Operations
Activity type: Homework / independent application
Objective: Distinguish an IPv4 address from a subnet prefix, network address, broadcast address, and usable host range
Requirements
Calculate the network address, broadcast address, conventional first host, conventional last host, and conventional host count for 192.168.12.201/27.
Divide 10.10.0.0/24 into four equal subnets and list each resulting CIDR prefix.
Given routes 0.0.0.0/0, 172.16.0.0/12, 172.20.0.0/16, and 172.20.8.0/24, identify the selected prefix for 172.20.8.44, 172.20.9.44, 172.31.1.1, and 8.8.8.8.
Draw a diagram showing a host, local switch, default gateway, and remote subnet. Label where direct delivery ends and routed delivery begins.
In your own words, explain why changing a host from /24 to /16 without changing its address can alter which destinations it treats as local.
