Network address: the IP address and subnet mask and operation, the result is a network address

Broadcast address: will get the same results in the network address of the host address into 1, the result is the broadcast address

Add 1 address range: network address, the broadcast address minus 1

Host:

Case 1:

IP address and subnet mask to operation, the result is a network address?

? 128? 36? 199? 3?????????????????????

? 255? 255? 240? 0??????

10000000? 00100100? 1100? 0111? 00000011????????

11111111? 11111111? 1111? 0000? 00000000??????

And computation results for the network address:

128? 36? 192? 0??

10000000? 00100100? 1100? 0000? 00000000

The broadcast address:?

128? 36? 207? 255????????

10000000? 00100100? 11001111? 11111111

Is the scope of this example network: 128? 36? 192? 1? To? 128? 36? 207? 254

Example 2:

255.255.255.240 respectively for the following

1100 0101.0110 0011.1101 1110.1000 1011

1111 1111.1111 1111.1111 1111.1111 0000

Binary phase: 197.99.222.128

The network address: 197.99.222.128

The broadcast address: 197.99.222.143

Address range: 197.99.222.129-197.99.222.142
