| IP option 0, End of options list |
Description:
This option indicates the end of the option list in the IP header. This might not coincide with the end of the header according to the header length. This is used at the end of all options, not the end of each option, and need only be used if the end of the options would not otherwise coincide with the end of the internet header.
