Learn how to establish a supernet handle

A community handle that’s produced by fusing many community addresses is called a supernet handle. The method of figuring out a supernet handle known as supernetting or classless inter-domain routing (CIDR).

The next steps can be utilized to establish a supernet handle:

As an illustration, let’s say there are two networks:

Two networks to generate a supernet address

To supernet these two networks, one wants to seek out the biggest community masks that may embody each of them. On this case, the biggest masks that will work is a /23 masks ( The brand new community mass will be obtained by counting the shared main bits within the community part of the addresses. This enables one to generate a supernet handle by aggregating each networks right into a single, bigger community, which they will characterize as:

Supernet address

This supernet can be utilized rather than the 2 particular person networks, and any IP handle throughout the vary of the supernet will probably be routed to the right vacation spot community. Supernetting helps to cut back the variety of routes within the routing desk, making it simpler for routers to handle community site visitors and enhancing the effectivity of IP handle utilization. Nevertheless, it is very important word that the method of supernetting requires a great understanding of web protocol (IP) addressing and community subnetting.

Benefits of supernetting

CIDR is a method used to create a supernet handle by combining a number of community addresses. It has a number of benefits, together with:
