1. Given the IP address (191.185.12.10), answer the following (Show your work):

• Using the priority bits, what is the class of this address?
• Assuming we are using the default subnet mask of the class, how many subnetworks can we create?
• Assuming we are using the default subnet mask of the class, how many hosts can we have in each subnetwork?

2. Given the IP address (10.18.10.13/28), answer the following (Show your work:)

• How many bits are allocated for (network, subnet (if any), hosts)
• What is the network address, broadcast address, first IP address, last IP address of this network?
• What is the network address, broadcast address, first IP address, last IP address of the 14^th network?

3. You work for a company, and the ISP provides you the address (10.18.10.0).

• What is the proposed prefix you may use? Why?
• What is the network address broadcast address for each department?
