IPv6 is a stronghold solution with all the required features built-in instead of stuck-on as an afterthought. When IPv6 becomes ubiquitous, software engineers can rejoice in the fact that they no longer need to deal with networking requirements. They can simply work on providing the best applications and let the relevant OS and hardware take care of network complexity.
This will lead to better and faster applications, ones that will use the network as it should be used. I can’t wait to see what developers are going to come up with.
Whatever it is, I know IPv6 will make their lives (and ours) easier.
