WebJul 6, 2024 · The IPv4 packet length, in other words, cannot be inferred from the LAN-level packet size. Because the Total Length field is 16 bits, the maximum IPv4 packet size is 2 16 bytes. This is probably much too large, even if fragmentation were not something to be avoided (though see IPv6 “jumbograms” in 8.5.1 Hop-by-Hop Options Header ).
WebApr 9, 2024 · Similarly, if the value in this field is 10, then the length of the header will be 10 x 4 = 40 bytes. 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. WebThe size of the IPv6 header has doubled from 20 bytes for a minimum-sized IPv4 header to 40 bytes. However, the new IPv6 header contains source and destination addresses that are four times longer than IPv4 source and destination addresses.
