I am still a beginner to subnetting, so please forgive the basic nature of the doubt.
When a network is subdivided into a subnet, won't the network broadcast address be the same as the last subnet's broadcast address.
For example, in the subnet 192.168.10.240/28, the broadcast address is 192.168.10.255. This is the same as the broadcast address of the whole network with network ID 192.168.10.0. Please help me understand this.
