A company would like to use the private 10 network address (10.x.x.x) for all hosts IP addresses.

This company currently has six campuses (1-6). Each campus has up to 12 buildings (B1-B12).

Each building has up to five floors (F1-F5) Each floor may have as many as ten departments (D1-D10).

We need to design different networks and create subnets that allow the IP address of a host reveal its location (which campus, building, floor, and department) Use the previous information, explained in lecture 4 network design example-2, to answer the following questions

Q1: The network IP portion of campus 3, building#5, floor#2, and department#2?

Q2: The first host IP address in the previous network?

Q3: The last host IP address in the previous network?

Q4: The broadcast IP address in the previous network?

Q5: The subnet mask of the previous network?

Use the lecture 4 network design example to answer the following questions

Q6: The network IP portion of campus 5, building#4, floor#4, and department#3?

Q7: The first host IP address in the previous network?

Q8: The last host IP address in the previous network?

Q9: The broadcast IP address in the previous network?

Q10: The subnet mask of the previous network?
