How to distinguish the IP address of the network, subnet, (takes up the host before several) host nu-CodePudding

Have a class C address is: 192.9.200.13
The default subnet mask is: 255.255.255.0

It network number and host number can be obtained as follows:

(1) the IP address 192.9.200.13
Converted to binary 11000000000010011100100000001101
(2) the subnet mask 255.255.255.0
Converted to binary 11111111111111111111111100000000
(3) the two binary number to do the bitwise and (& amp;) Results after operation is the network part

=192. 9. 200. 0
The network number for 192.9.200.0

(4) to take the subnet mask to the IP address the bitwise and (& amp;) After the result is the main part

=0. 13
0. 0.The host number 13 (or 0.0.0.13),
