Difference between Subnetting and Supernetting

Subnetting:
Subnetting is the procedure to divide the network into sub-networks or small networks. 

Supernetting:
Supernetting is the procedure to combine the small networks into larger space. In subnetting, Network addresses’s bits are increased. on the other hand, in supernetting, Host addresses’s bits are increased. Subnetting is implemented via Variable-length subnet masking, While supernetting is implemented via Classless interdomain routing. 

Difference between Subnetting and Supernetting:

S.NO	Subnetting	Supernetting
1.	Subnetting is the procedure to divide the network into sub-networks.	While supernetting is the procedure of combine the small networks.
2.	In subnetting, Network addresses’s bits are increased.	While in supernetting, Host addresses’s bits are increased.
3.	In subnetting, The mask bits are moved towards right.	While In supernetting, The mask bits are moved towards left.
4.	Subnetting is implemented via Variable-length subnet masking.	While supernetting is implemented via Classless interdomain routing.
5.	In subnetting, Address depletion is reduced or removed.	While It is used for simplify routing process.
