Question

9. A network on the internet has a subnet mask of 255.255.240.0. What is the maximum number of hosts it can handle?"

Answer 1

Answer:

class B subnet is 255.255.0.0

but given is 255.255.240.0, i.e, 4 bits are stolen from the host .

Hence , total subnets will be ==> 24 - 2 = 14 and 12 host bits are left.

So,total hosts ==>  212 - 2 = 4096 - 2 = 4094

Explanation:

Answer 2

Maximum number of hosts it can handle:

Explanation:

• 2-2=14 subnets

• 2-2=4094 hosts per subnet

• 256-240=16.0, 32.0, 48.0, 64.0, etc.

• Broadcast for the 16.0 subnet is 31.255. Broadcast for the 32.0 subnet is 47.255, etc.

• The valid hosts are:

• Subnet        16.0       32.0     48.0    64.0

• first host        16.1        32.1   48.1     64.1

• last host      31.254  47.254  63.254  79.254

• broadcast   31.255    47.255  63.255 79.255
