Some common algorithms in the computer network

Algorithm for network address and host address:

The mesh mask is converted to 2, and then to the IP phase, the network address can be obtained. The host address is the part that removes the network address. For example: IP is 192.168.26.100 Subnet Mask is 255.255.255.0 its network address is 192.168.26.0 host address is 0.0.0.100

For example: The network 117.15.32.0/23 divided into 117.15.32.0/27, the resulting subnet is (), each subnet can be used in the host address is () a

Then 23 to 27 can divide a maximum of 16  host addresses even if: 32-27 = 5     Then 2^5-2 = 30
