hi,

What is Superneting? Explain the concept of custom Subneting.


Supernetting or Classless Inter-Domain Routing (CIDR)

It is a way to aggregate multiple Internet addresses of the same class.
The adjacent network address (eg:192.168.2.0/24 and an address 192.168.3.0/24) can be merged (into 192.168.2.0/23) using supernetting.
Supernetting is the basis for most routing protocols currently used on the Internet.
It is mostly used to combine Class C network addresses.


Subneting is a process of breaking the network into smaller units. These units care called as subnets. Here a subnet could be several machines in a single LAN. Networks using IP can create sub networks of logical addresses. With every IP address there some of the bits in the machine can be used to identify a specific subnet. The IP address then contains three parts: the network number, the subnet number, and the machine number.

What is custom Subneting?

Subnets that can be customized; i.e. modifying the dividing point between subnet ID and host ID to suit the needs of our network. The subnet mask that we use when creating a customized subnet is, called a custom subnet mask. This custom subnet mask is used to find the customization..
