This is for my Net+ class. working with subnetting came hard to me when I did the CCNA class (no didn't pass the exam) and now it is still not sinking in like I wish it would. I think I have it figured out. If someone that knows what they are talking about can tell me if I am on the correct track and if not offer me a hand I would very much appreciate it. The question: IP address: 184.108.40.206 you need 12 subnets. The subnet mask is 255.255.240.0 this is done borrowing 4 bits. I am going to list what I got as the first 2 subnets and there host addresses. If you agree, then I have it figured out and don't need any help. If I am missing something, it will show up here: Subnet 1: 220.127.116.11 through 18.104.22.168 Subnet 2: 22.214.171.124 through 126.96.36.199 Thanks for your help.
