Network Math - the Mighty Checksum!
Many of the main protocols in use today compute a checksum in order to verify that there is nothing wrong with the header. The header contains all of the protocol goodness such as addressing. This is the case with the Internet Protocol (IPv4 and IPv6). Other protocols such as TCP and UDP also add the pseudo-header to the calculation.
In this video, I will show you where the checksum can be found and go through an example on an actual packet. Now, into the header!
