Advantages of IPv6

While simply having an IPv6 gateway may seem ideal, it does not provide you with the full volume of benefits offered by the IPv6 suite. In addition to the increased address space available to IPv6 users and the future proofing this entails, there are a number of other benefits of IPv6.

The first advantage is a decrease in the amount of processing needed by routers to forward IPv6 packets. This is due to a reorganization in the way that IPv6 packets are structured. With hindsight, the less-used options of the packet are placed in a trailing optional section. This means that routers can find the information they need much more readily.

The second advantage is in the processing of message sub-blocks. When transmitting an IP packet (v4 or v6), the packet can be split up into smaller chunks called fragments for easier transmission over a network. For IPv4, these packets are then reassembled again between routers, which can add delay - especially if a packet is lost. In IPv6, only the destination is responsible for the reassembly of packets, which cuts down considerably on the trip time over networks that fragment packets.
