What is the difference between supernetting and subnetting

It results in the creation of more host addresses at the expense of network addresses, where basically the network bits are converted into host bits. The supernetting is performed by internet service provider rather than the normal users, to achieve the most efficient IP address allocation.

CIDR is a supernetting technique where the several subnets are combined together for the network routing. In simpler words, CIDR allows the IP addresses to be organized in the subnetworks independent of the value of the addresses.

Subnetting and supernetting both the terms have inverse meaning where subnetting is used to separate the smaller subnetworks form each other by dividing a larger network. Conversely, supernetting is used to combine the smaller range of addresses into a larger one to make routing process more easy and fast.

Ultimately, both techniques are used to increase the availability of the IP addresses and reduce the depletion of IP addresses. Your email address will not be published. Key Differences Between Subnetting and Supernetting The strategy used to divide a huge network into smaller subnetworks is known as subnetting.

On the contrary, supernetting is the technique of merging multiple networks into a single one. The subnet masks are In simple routing environments, such as a home network, a single private network merely routes to an Internet connection. In complicate routing environments, such as a campus area network that connects multiple buildings and organizations, you must use multiple routers.

Subnets help divide and manage users at the local level. For example, if you have graphics design staff and music staff, housed on separate floors of the same humanities building of a university campus, you could use the This allows the central router to simplify its routing and security rules.

For example, The major objective of Supernetting is to convert all the network related bits into the host bits. Notify me of follow-up comments by email. Notify me of new posts by email.

Post author: Rupesh Rawat Post category: Articles A network can be defined as a group of two or more computers that can communicate with each other in order to share data and resources.

Key Differences: The subnetting is the technique to divide the network into smaller subnetworks. Using subnetting, we can divide the network into subnets for different departments. For example, all the devices in the Human Resource department belong to one subnet while all the devices in the Finance department belong to one subnet. It avoids running out of IP addresses and helps to assign IP addresses to all the devices.

Moreover, all hosts in one particular subnet belong to the same broadcast domain. Therefore, it is easier to send a broadcast message to all hosts easily at once. Subnetting also improves security issues. Supernetting is the process of combining multiple networks to build a single network.

Supernet or super network refers to this new network. Supernetting helps to minimize the size of routing tables and routing table updates.
