IP subnetting and vlsm (variable length subnet mask) and route summarization

IP subnetting and vlsm (variable length subnet mask)

IP subnetting and vlsm (variable length Subnet Mask) are calculated manually.

Structural and hierarchical addressing technology for large-scale IP networks.

The main network of IP:

The IP network number that is the same as the IP main class address mask is called the IP main class network

All 0 network address all 1 is a broadcast address

Class A: 10.0.0.0amp 8 decimal range: number of hosts in the 1-126 network = 2 to the 24th power-2

Class B: 172.16.0.0amp 16 decimal range: number of hosts in 128-191 network = 2 to the power of 16-2

Category C: 192.168.1.0 Universe 24

Decimal range: number of hosts in 192-223 network = 2 to the power of 8-2

Class D address for Multicast Communication

Class E address is used for scientific research reservation

Category A: 10.0.0.0-10.255.255.255

Category B: 172.16.0.0-172.31.255.255

Class C: 192.168.0.0-192.168.255.255
