WebIP header: Variable length of 20-60 bytes, depending on IP options present. Fixed length of 40 bytes. There are no IP header options. Generally, the IPv6 header is simpler than the IPv4 header. IP header options ... For IPv4, 576 is the typical minimum. IPv6 has a lower boundary limit on MTU of 1280 bytes. That is, IPv6 does not fragment ... 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. Table 4-2 lists the individual differences between the IPv4 and IPv6 header fields. Table 4-2. IPv4 ...
