What is the checksum value calculated at destination?

I didn't read the question properly. Question is asking for the destination checksum. 4500 + 003C + 1C46 + 4000 + 4006 + 0000 + AC10 + 0A63 + AC10 + 0A0C = 24E17. Now add the carry bit. 2+ 4E17 = 4E19. For destination. FFFF - 4E19 = B1E6.. 2 votes 2 votes Shobhit Joshi commented Dec 24, 2018 reply Follow Share @kumar.dilip should have removed 0000 as it is the checksum, doesn't affect the answer but still 0 votes 0 votes Please log in or register to add a comment.
