Computer Networks : Using DBA instead of LBA
Going through the concept of LBA (Limited Broadcasting) and DBA (Directed Broadcast Address), if i consider two cases Case 1 : when host A (10.1.2.3) want to send the packet to all the nodes of a DIFFERENT Network (say 11.0.0.0), in ... 255.255.255) in Case 2, why can't i just use DBA (Directed Broadcasting), making the Destination IP 10.255.255.255 ?
