Site Details and Challenges (Summary) When locating subnets for the VLANS, it is important to understand the standard notation of an IP address and be knowledgeable of the Classes of networks, and what subnet mask for each network looks like. Understanding the range of IP addresses that can be used and how to come up with that range. You will need a basic understanding of subnetting to come up with the proper address ranges, and subnet mask. Also, knowing what IP broadcasting is will help you to determine the broadcast. If calculations are performed in correctly, it is possible to have a range that is too large or too small and you will end up with an error that will not allow you to move forward.
