#1
You are the system admin for an insurance company with 10 departments. You have been given a class C IP network by your ISP. The network is: 205.153.202.0

You must subnet your class C network into at least 10 subnets. What will the subnet mask of your router be to accommodate this need. How many sub-networks must you create within your class C network to have the needed 10? What are the networks? Please list the IP ranges for each subnet.


#2

Subnet a class B IP network into 30 useable subnets.

What is the subnet mask for this class B network?


#3

Subnet the Class C network, 212.54.52.0 into 30 useable subnets.

List the subnet mask for this configuration and show the the IP ranges for each subnet.

If I answer this can I have your Red Hat certification?

But seriously folks... This is a subject covered in the basics of MCSE, CNA/CNE tutorials as well as the RedHat stuff. Check out the Net How-To at linuxdoc.org

You'll need to break out the subnets, masking and routing info for the nets you want to create.
