Do you want to know about supernet and you have just heard about it for the first time? You are thinking that what is this. Don’t worry I am here to help you. Here I will explain everything related to the supernet internet. Just relax, we will discuss some of the important things that you should know about it. I will describe to you the process for how to do it, what is it, etc. So let us begin with the meaning of it.

What Is A Supernet?

A supernet is an Internet Protocol (IP) network that is built into a larger network by combining several networks known as subnets. It is also called a super network. In a single routing table entry, if there is a new routing prefix for the combined network then it reflects the constituent networks. Super netting, link aggregation, prefix aggregation, or route summarization is called the method of creating it. You will see to calculate the network you will require a supernet calculator and you will need the IP address values.

Components In It

Following are the components used for the super network process.

  • Network ID
  • CIDR Value
  • Broadcast ID
  • Subnet Mask 
  • Block Size of each route

Its Work

The super network does its work by combining multiple Class C networks in the form of blocks instead of dividing them into segments. However, a combination of the supernet subnet has different work. While the process of subnetting, the host Id gives bits that increase the number of bits for the Network ID.

Rules 

There are some rules for how to create it. These rules will help you in the supernet example.

  • All the networks should be contiguous.
  • Determine the number of networks to be grouped and verify that this number is in the range of 2.
  • Compare the value of the first non-common octet in the first one that is the lowest IP address block in the list of networks to be indexed to the number of networks to be grouped, which is also the order of 2.

Purpose 

The purpose of it is for the management of the routing tables, which is a summary of networks that are known as the tables. It will help you in communications through a single big network. There is a school called Supernet virtual school you can enroll yourself by doing registration. You will get these tables from the routers, that help us in finding a new path and locate the best path for the destination.

Protocol Requirements 

Following protocols are required for super networking. The Classless Inter-Domain Routing (CIDR) is supported by the protocols given below.

  • Interior Gateway Routing Protocol
  • Exterior Gateway Protocol
  • Routing Information Protocol (RIPv1)
  • Enhanced Interior Gateway Routing Protocol
  • Border Gateway Protocol
  • Open Shortest Path First

Benefits Of Supernet Communications

Below we have mentioned the benefits of it.

  • It manages the IP supernet address space
  • There is an Increase in routers in terms of memory storage of route info
  • It prevents the IP address from topological fragmentation
  • When matching routes the overhead processing is done.
  • The time required for rebuilding the routing tables is reduced with it.

Risks Of Supernet

The below are the risks that you can be identified in it:

  • It is applied to various routers in different ways.
  • On one router interface, it will affect how routes are advertised on other routes of the same router.
  • Detecting a continuous routing loop becomes a challenging task in the presence of this.

Difference Between Supernet Vs Subnet

Here we have mentioned the difference between super net vs subnet below:

  • In a super network, the process is called super netting. In subnet, the process is called subnetting.
  • In the super netting, smaller sets of addresses are combined in large spaces. While in the subnet network a large network is divided into smaller networks is subnetting.
  • Super networking is executed through classless interdomain routing. While subnetting is achieved by variable-length subnet masking.

Creating A Supernet

Below we have mentioned the process for how to create a super network for your network components setup.

  1. Click IP Address Manager
  2. Then Click Manage Subnets and IP Addresses.
  3. Select the network, or group that you desire
  4. Now add network.
  5. Click on Add
  6. Click on the Supernet.
  7. Enter a name for your subnet.
  8. Enter the super netting address 
  9. Enter the CIDR prefix length.
  10. Write a description of it, this is optional.
  11. Define custom properties
  12. Enter and provide values.
  13. Configure it
  14. Click Save.

FAQ

What Is Supernet Networking?

A supernet networking is an Internet Protocol (IP) network that is built into a larger network by merging several networks or subnets. Super netting, prefix aggregation, link aggregation, or route overview is called the method of creating a network.

What Is Supernetting With Example?

It is the method of reviewing several numbers of subnet networks into a single wide network. This is also known as making summaries of the routes and grouping of routes. It is a process of combining small networks to form a larger network.

Why Do We Need Supernetting?

It is required for the primary purpose to reduce the scale of the routing table on routers. For example, it can have a group of the route of the 8 individual routes instead of a router having 8 individual routes.

What Is The Difference Between Subnet And Supernet?

Here we have mentioned the difference between super net vs subnet below:

  • In super network, the process is called super netting. In subnet, the process is called subnetting.
  • In the super netting network, smaller sets of addresses are combined in large spaces. While in the subnet network a large network is divided into smaller networks is subnetting.
  • Super networking is executed through classless interdomain routing. While subnetting is achieved by variable-length subnet masking.

Conclusion

In the above, you read about the supernet in detail. I described what is it, working of it, challenges, etc. You read about the risks, examples, differences of it with the subnet that we discussed. I explained to you some of the frequently asked questions that come into many people’s minds, So after reading the above information you find it is useful and now know about the supernet.
