Use an online random IP generator. For each IP, give it a random slash (e.g., /19 , /26 , /23 ). Write down the answers.

Quick reference: host counts by mask
If you are studying for the CCNA, Network+, or any IT certification involving TCP/IP, you have likely hit "the wall." You understand what a subnet mask does theoretically. You know the difference between a Class C and a Class A address. But when the exam timer starts ticking, you freeze. Use an online random IP generator

To build a better workbook than what's available, you should create your own exercises and solve them using a consistent framework.
, identify how many bits are used for the network and how many are used for the host. Network bits: (indicated by the /29 CIDR notation). Host bits: (Total bits in IPv4 are ; therefore, Problem 2: Determining the Subnet Address Question: A host is assigned the IP address . What is the subnet address to which this host belongs? Solution: Identify the Subnet Mask: A mask in binary is , which is in decimal. Determine the Magic Number:
