the question is, calculate these information:
"ip subnet zero, first ip, last ip, broadcast, ip subnet mask"
for a Class B IP (172.16.0.0/16) for X number of PCs, for example, for 27811 computers...
Address: 172.16.0.0 10101100.00010000 .00000000.00000000
Netmask: 255.255.0.0 = 16 11111111.11111111 .00000000.00000000
Wildcard: 0.0.255.255 00000000.00000000 .11111111.11111111
=>
Network: 172.16.0.0/16 10101100.00010000 .00000000.00000000 (Class B)
Broadcast: 172.16.255.255 10101100.00010000 .11111111.11111111
HostMin: 172.16.0.1 10101100.00010000 .00000000.00000001
HostMax: 172.16.108.163 10101100.00010000 .11111111.11111110
Hosts/Net: 27811 (Private Internet)
For a Class B IP address the first 16 digits should be static(they will never change). The remaining 16 digits keep changing...
So for ur problem.. the IP addresses go like this...
172.16.0.1 ..... 172.16.0.255
172.16.1.0 ..... 172.16.1.255
.
.
.
172.16.107.0 ..... 172.16.107.255
172.16.108.0 ..... 172.16.108.163 ---> This will count to 27811 hosts
