WebIPv6 has eight header fields with a 40-character length; IPv4 has 20 header fields with an eight-character length. IPv6 does not have any checksum fields. To map MAC addresses, IPv6 uses NDP (Neighbor Discovery Protocol), while IPv4 uses ARP (address resolution protocol). This was last updated in September 2024 Continue Reading About IPv6 address WebNov 15, 2024 · IPv6 could theoretically be quicker so no cycles are lost on NAT translations. However, IPv6 uses larger packets, which can make it slower in certain situations. What really differentiates IPv4 networks from IPv6 networks at this stage is that IPv4 networks are more mature and therefore highly optimised.
