Netmask:
The netmask is calculated by putting the number of 1’s equal to the given mask value (here 22).
Netmask = 11111111.11111111.11111100.00000000
= 255.255.252.0
Therefore, the netmask is equal to 255.255.252.0
Network Address:
The network address is obtained by performing the AND operation of the bits in the given IP address with the bits of the netmask.
IP address (153.10.22.56) = 10011001.00001010.00010110.00111000
Netmask (255.255.252.0) = 11111111.11111111.11111100.00000000
Network address = 10011001.00001010.00010100.00000000
= 153.10.20.0
Therefore, the network address is equal to 153.10.20.0
Host Mask:
The remaining or the unused bits in the netmask are used as the host mask. In other words, the host mask is obtained by complementing each bit of the netmask.
Netmask = 11111111.11111111.11111100.00000000
Host mask = 00000000.00000000.00000011.11111111
= 0.0.3.255
Therefore, the host mask is equal to 0.0.3.255
Broadcast address:
The broadcast address is used to send the packages to all the hosts in the network. It is obtained by setting all the bits after the network address to 1.
Network address (153.10.20.0) = 10011001.00001010.00010100.00000000
Broad cast address = 10011001.00001010.00010111.11111111
= 153.10.23.255
Therefore, the broadcast address is equal to 153.10.23.255
The number of possible hosts:
The number of possible hosts is computed as follows:
Possible hosts = 2n, where n is the number of host bits.
Out of the above 2n hosts, 2 are reserved and hence the number of usable hosts is equal to 2n – 2.
Number of hosts = 210 – 2 = 1024 – 2 = 1022
Host number:
Host number is the decimal equivalent of the host bits in the IP address.
Ip address (153.10.22.56) = 10011001.00001010.00010110.00111000
Host bits = 10.00111000
Host number = 29 + 0 + 0 + 0 + 25 + 24 + 23 + 0 + 0 + 0
= 512 + 32 +16 + 8
= 568
Hence, the host number is equal to 568.
