Subnetting is a best technique for network.When we split a large n/w into small n/w it is a called Subnetting. with the help of subnetting we can reduce the N/w congetion. Because all coputer broadcast for transmission. So we break huge network into small network and now broadcasting will be done only small network.

Wth the help of subnetting we can save money. Because we buy an single IP address from ISP and  encrese the IP address from Subnetting.

That's why we can say that subnetting is best tool for encrese bandwidth and save the money.

Advantage of subnetting include improved security ( by restricting unauthorized traffic behind routers) and simplified administration (by delegating control of subnets to other departments or administrators ).

Subnetting is a technique using which we can create segments in a large netwroks.

lets go by an example..where we have private ip address n/w /8.
What this means is that we will have 2^24 -2 address in the same network..so broadcast will go to all the addresses in this n/w.
But if we subnet the n/w we can create multiple n/ws ...since by default routers won't allow broadcasts to be sent to other n/w..we can manage our n/ws in a better way.

If a problem is occured in any specific segment..it won't affect other segments.

We can also save precious ip addresses in a network using subnetting.
