So we need a network id for broadcasting.Both the ID is class ‘A’ IP having the same network id which is 20.0.0.0, So DBA will be the same 20.255.255.255so when a data packet is sent with DBA 20.255.255.255 to which network this data will be sent ?To all the devices in the network 20.0.0.0 0 votes 0 votes JAINchiNMay commented Aug 5, 2022 reply Follow Share Classless IP addressing is there. In broadcasting we need DBA not network ID. 0 votes 0 votes raja11sep commented Aug 5, 2022 reply Follow Share ok 0 votes 0 votes Abhrajyoti00 commented Aug 5, 2022 reply Follow Share @JAINchiNMay Dude this is seriously a great question. I have some insights… Since they have the same DBA so the packet must be forwarded to all the hosts in both of these networks. Now, what I’m thinking is if it’s passed on to Network with ID 20.0.0.0 shouldn’t one of it’s hosts, i.e., 20.255.0.0 receive the packet? 1 votes 1 votes samarpita commented Aug 6, 2022 reply Follow Share @raja11sep what he told, I totally agree with him. If it is classless, also 20.255.0.0/16 and 20.0.0.0/8, “this 20.255.0.0/16 will fall under this n/w id 20.0.0.0/8”. And if you think that 20.255.0.0/16 and 20.0.0.0/16, then the DBA will be 20.255.255.255 and 20.0.255.255 respectively. 0 votes 0 votes JAINchiNMay commented Aug 6, 2022 i edited by JAINchiNMay Aug 6, 2022 reply Follow Share @samarpita I agree with your second statement but can you explain 1st statement. 0 votes 0 votes JAINchiNMay commented Aug 6, 2022 i edited by JAINchiNMay Aug 6, 2022 reply Follow Share @Abhrajyoti00 ohk now I got your point thanks!!! 1 votes 1 votes Please log in or register to add a comment.
