What is the broadcast IP address?

192.168.1.255
127.0.0.1
10.255.255.255
255.255.255.255

The correct answer is: 255.255.255.255

The broadcast IP address is used to send network packets to all possible destinations on a given network segment. In most cases, it is the highest address in a particular subnet. The address 255.255.255.255 is a limited broadcast address, meaning that it broadcasts packets to all hosts on the local network. This address is not routed and is used for network initialization and discovery processes. The address 192.168.1.255 is also a valid broadcast address, specifically for the subnet 192.168.1.0/24, but it is more specific to that subnet rather than serving the general broadcast capabilities indicated by 255.255.255.255. The address 127.0.0.1 is a loopback address used for internal testing on a device, rather than a broadcast address. Similarly, 10.255.255.255 is a broadcast address for the 10.x.x.x private network range, but it isn't a universal broadcast address like 255.255.255.255. Overall, 255.255.255.255 serves as the general broadcast address, making it the correct answer in this context.
