Identify the broadcast address from the following.1 point192.168.0.255/16192.168.12.127/25214.19.21.255/1410.24.36.48/28

To identify the broadcast address from the given options, we need to understand the concept of broadcast addresses in IP networking. The broadcast address is the last address in a subnet, used to communicate with all devices in that subnet.

Let's analyze each option step by step:

1. 192.168.0.255/16

   • Subnet Mask: /16 means the subnet mask is 255.255.0.0.
   • Network Address: 192.168.0.0.
   • Broadcast Address: The last address in the subnet 192.168.0.0/16 is 192.168.255.255.
   • Given Address: 192.168.0.255 is not the broadcast address for this subnet.

2. 192.168.12.127/25

   • Subnet Mask: /25 means the subnet mask is 255.255.255.128.
   • Network Address: 192.168.12.0.
   • Broadcast Address: The last address in the subnet 192.168.12.0/25 is 192.168.12.127.
   • Given Address: 192.168.12.127 is the broadcast address for this subnet.

3. 214.19.21.255/14

   • Subnet Mask: /14 means the subnet mask is 255.252.0.0.
   • Network Address: 214.16.0.0.
   • Broadcast Address: The last address in the subnet 214.16.0.0/14 is 214.19.255.255.
   • Given Address: 214.19.21.255 is not the broadcast address for this subnet.

4. 10.24.36.48/28

   • Subnet Mask: /28 means the subnet mask is 255.255.255.240.
   • Network Address: 10.24.36.48.
   • Broadcast Address: The last address in the subnet 10.24.36.48/28 is 10.24.36.63.
   • Given Address: 10.24.36.48 is not the broadcast address for this subnet.

From the analysis, the correct broadcast address is:

192.168.12.127/25
