SOME QUERY
1. 192.168.0.1 (IP ADDRESS)
255.255.255.128 (Subnet Mask)
(IP address is the Class C Address) We have to see the Host that is 128
ON Bits(1) is 1 AND OFF Bits (0) is the 7 see in the Table
So
Network = 2^1 ==>2
Host =2^7-2 ==>128-2 ==> 126
So the Network is 2 and Host is 126
Now we have to allocate the IP Address
Network no. 1
192.168.0.0(Network ID)
192.168.0.1
192.168.0.2
192.168.0.3
