What is a subnet?
A subnet, or subnetwork, is a network inside a network. Subnets make networks more efficient. Through subnetting, network traffic can travel a shorter distance without passing through unnecessary routers to reach its destination.
Subnetting allows creating smaller network (sub networks or subnets) inside a large network by borrowing bits from the Host ID portion of the address. The borrowed bits can be used to create additional networks, resulting in smaller-sized networks. This can help to reduce :
- Wastage
- Improve network performance
- Effective isolation
- Easier administration
Step 1 is to propose a private addressing system for usage in the Cobham Collage campus network. In term of private addressing scheme, our Cobham Collage campus network is using Class C private network addressing which is 192.168.0.0/16. In this case Cobham Collage, there are 7 different facilities with 1 IT center. Each facility is given their network address respectively. From this network address , the 5th available address is assigned as the address of the Online Learning System Server.
FLSM to determine subnetting depending on the number of the faculties.
