Is it really worth upgrading from IPv4 to IPv6? These are all excellent questions, and you probably already have your answers. Of course, there is that group of people who are known as "change deniers", but don't listen to them. If we had listened to them years ago, we would still be waiting weeks, if not months, to receive a letter from the Pony Express. So, now we need to shout our answer "Yes"! Not only does IPv6 provide us with a lot of addresses (3.4X 1038 = definitely enough), but it also provides many other features that make it worth the resources, time and effort to migrate from IPv4 to IPv6oMigrating IPv4 to IPv6 provides the following benefits.. Using IPv6 eliminates the need to use NAT.IPv6 provides more than enough addresses to assign more than 4 billion IP addresses to every person on the planet.. IP addresses can be assigned to hosts without the use of DHCP.Today's networks, including the Internet, have many needs that could not and did not anticipate when IPv4 was created. To meet these new needs, we tried to add feature sets to IPv4, but this moveWhat's really exciting about IPv6 is its efficient features! Let's start at the beginning. The number of fields in the IPv6 packet header is half that of IPv4, 64 bits in total, which greatly improves processing speed - compared to IPv4, the lookup speed is lightning fast! Most of the information in the IPv4 header has been removed from the IPv6 header, but you can optionally add this information or parts of it back in as an extended header after the basic header fields.The new address space in IPv6 (3.4X 1038 - enough to allocate 4 billion addresses to every person on the planet) has already been mentioned. But how can these addresses be obtained? Are they going to just doodly appear like Chris Angel, the magical magician, and then they'll be everywhere? I mean, such a huge cluster of addresses has to come from somewhere! The fact that IPv6 gives us such a huge address space means that the address itself is a lot longer - in fact it's four times the length of an IPv4 address! The length of an IPv6 address is 128 bits, so don't worry, the next146
