Question

What is the subnet address if the destination IP address is 144.16.34.124 and the subnet mask is 255.255.240.0?

Answer 1

Answer:

144.16.32.0

Explanation:

by look that 144 ... we can conclude that it is class b network. so we need to convert that destination ip address(144.16.34.124) into binary.the natural mask of class b network is 255.255.0.0 ...convert this natural mask into binary form . and apply (AND operation).by that we get network address.

to get subnet address ....

convert that 34 in destination ip address(144.16.34.124) into binary form.

and also convert that (240)subnet mask address(255.255.240.0) into binary

and apply (AND operator).we will get the subnet.
