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. http://3coptics.com/News/73.html

WebApr 9, 2024 · The IPv6 header is a streamlined version of the IPv4 header. It provides new features while retaining the core concepts that made IPv4 popular. It eliminates the fields that are rarely used, improves the remaining fields, and adds an additional field to provide better support for real-time traffic. 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).
