I am working on a project in which I need to add some options in the IPv4 header field. I am following this draft for the implementation. I have a doubt!
As the above mentioned draft says, I need to add atleast 32*5 = 160 bits to the header of IP packet but as far as I know the Options field in the IP header is only limited to 32 bits. How can I add options which have length more than 32bits? Also what should be the right approach for adding options if there are some options already present in the header!
