Such as a class C address of the network is the first 24 bits, that is to say A.B.C.H ostNo A.B.C is network a
Then why use subnet mask to determine whether to belong to the same network?
192.168.1 and 192.168.2 cannot represent the two networks?

CodePudding user response:

These should be in the basic knowledge of CCNA is
Mask can judge the network range,
192.168.1 and 192.168.2 isn't the same network depends on their mask size
If the mask is 23, that they are of the same network

With operation IP and mask so I can understand, but don't know the IP address is divided into the meaning of the network and host bits, since all call network a, that how to embody the meaning of the network?

Different network segment, used to limit the broadcast packets

Didn't quite understand the role of network a, can you detail again. Thanks

Still not sure what network role, can again a little bit in detail, please thank

192.168.1.0 mask if is 24, then address range is from 255 to the broadcast address 192.168.0.1-192.168.0.254
192.168.1.0 mask if is 25, then address range is from 127 to the broadcast address 192.168.0.1-192.168.0.126

So, the mask delimits the scope of the radio
