Generally, the broadcast address is found by taking the logical bit complement of the subnet mask and then logically ORing this with the IP address.
Example: to broadcast a packet to an entire class B subnet using a private IP address space, the broadcast address would be 172.16.255.255.
This can be found from the subnet mask (255.255.0.0) and the IP address (eg. 172.16.48.196 - the complement of the subnet mask is 0.0.255.255, and 172.16.48.196 || 0.0.255.255 = 172.16.255.255.
