Question

Calculate the network address given the following information. (Remember to use the trick taught in class) /29

a) /32
b) /30
c) /28
d) /24

Answer 1

To calculate the network address, set the host bits to 0 according to the subnet mask. Examples given for different subnet masks.

Step-by-step explanation:

The trick taught in class to calculate the network address is to determine the number of host bits in the subnet mask. The subnet mask is represented by the slash notation (/X), where X is the number of bits that are set to 1. To calculate the network address, you need to set all the host bits in the IP address to 0, according to the number of host bits in the subnet mask.

For example, for a /29 subnet mask, there are 3 host bits. So, if the IP address is 192.168.1.50, the network address would be 192.168.1.48.

Using this trick, you can calculate the network address for each given subnet mask (/29, /32, /30, /28, and /24) by setting the appropriate number of host bits to 0 in the corresponding IP address.
