The final segment is the one to which ServerB connects. From the calculations done in the previous step, you can see that ServerB’s address lies in the 192.168.2.128 subnet. The valid host addresses in this subnet are 129 to 190. 191 is the broadcast address of the subnet. While the router (default gateway) is configured with a valid address, ServerB has been assigned the broadcast address, which needs to be changed. This explains why HostA is not able to reach ServerB.
