If an IPv4 option is not an integral multiple of 4 bytes in length, the remaining bytes are filled through padding options. The minimum size of the IPv4 header is 20 bytes. The maximum size of the header including all options is 60 bytes. WebbUnlike IPv4 options, IPv6 extension headers can be of arbitrary length. Also, the number of options that a packet carries are not limited to 40 bytes. This feature, plus the manner in which IPv6 options are processed, permits IPv6 options to be used for functions that are not practical in IPv4.
