Disadvantages of Subnetting
The disadvantages of Subnetting are mentioned below:
- In the case of a single network, only three steps are required to reach a Process i.e Source Host to Destination Network, Destination Network to Destination Host, and then Destination Host to Process.
- In the case of a Single Network only two IP addresses are wasted to represent Network Id and Broadcast address but in the case of Subnetting two IP addresses are wasted for each Subnet.
- The cost of the overall Network also increases. Subnetting requires internal routers, Switches, Hubs, Bridges, etc. which are very costly.
Introduction To Subnetting
When a bigger network is divided into smaller networks, to maintain security, then that is known as Subnetting. So, maintenance is easier for smaller networks. For example, if we consider a class A address, the possible number of hosts is 224 for each network, it is obvious that it is difficult to maintain such a huge number of hosts, but it would be quite easier to maintain if we divide the network into small parts.
