however, use a specific code for padding. In this case, the checksum calculation is executed including the padding
data. Consequently, the calculation result and the checksum contained in the header do not match. In this case, the
checksum of the padding data must be corrected by software.

The minimum packet length is 64 bytes. When padding a short packet, many systems use 00H. Some systems,
Caution According to RFC1071 if the checksum result is compared using the same endian format, the
result can be compared regardless of whether the data is in big endian or little endian format
when the checksum is calculated.
