Compute the Internet checksum for the data block E3 4F 23 96 44 27 99 D3. Then perform the verification calculation.
I know that there is the answers to this online. I would like a detailed walk through on this. I do not know how to check hex checksums. Am I suppose to convert the hex numbers? How do I do that?
Message:E3 4F 23 96 44 27 99 D3
2s complement sum is:1E4ff
1s complement sum is :1e4ff+1=e500
so internet check sum is 1aff
note that message + checksum=ffff
thus,check sum(msg+checksum)=0000
