IPv4 SubNetting Subnetting It allows you to take one larger network and break it into a bunch of smaller networks.
Advantages of Subnetting: 1. Reduced network traffic – Routers create broadcast domains. The more broadcast domains you create, the smaller the broadcast domains and the less network traffic on each network segment. 2. Optimized network performance – This is a result of reduced network traffic. 3. Simplified management – It’s easier to identify and isolate network problem in a group of smaller connected networks than within one gigantic network. 4. Facilitated spanning of large geographical distances - A single large network that spans long distances can create problem in every area. Connecting multiple smaller networks makes the system more efficient.
How to create SubNet? To create Sub Networks, we need to take bits from the host portion of the IP address and reserve them to define the subnet address.
Subnet Mask A mask used to determine what subnet an IP address belongs to. An IP address has two components, the network address and the host address.
