子网划分:
子网划分是将网络划分为子网络或小型网络的过程。
超网:
超网是将小网络组合成更大空间的过程。在子网划分中,网络地址的位数会增加。另一方面,在超网中,主机地址的位增加。子网是通过可变长度子网掩码实现的,而超网是通过无类域间路由实现的。
子网划分和超网划分的区别:

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. |
