The default subnet mask for Class B is 255.255.0.0. Thus an extra 8 bits have been used for the network portion, leaving 8 for hosts. The 2n - 2 formula (28 - 2 in this case for both the network and IP hosts) gives us 254 networks and 254 hosts per network. B类默认的子网掩码...
解析:Explanation:Using the 2n-2 formula for host addresses, 29-2 = 510 host address, so a 9-bit subnet mask will provide the required number of host addresses. If these 9 bits are used for the hosts in a class B network, then the remaining 7 bits are used for the number of networ...

The subnet mask for 4 bits is then 255.255.255.240.Incorrect Answers:A. This will give us only 2 bits for the network mask, which will provide only 2 networks.B. This will give us 3 bits for the network mask, which will provide for only 6 networks.D. This will use 5 bits for the...
if we take /23 notation for 172.16.0.0 class B network,we will get 128 network and 510 hosts.Here we are borrowing 7 bit for network and 9 bit for host(2^7=128 and 2^9=512) So each network having 510 host Starting & ending ip would be 172.16.0.1 to 172.16.1.254. Next network ...
