To be more specific to my point -- Using the internet today, with the demands of streaming real-time applications, which require a level of QoS wasn't originally designed in to IPv4. With a wide array of mods, patches and additions, there is 'some' support for prioritization. We would be better off with a protocol suite like v6 that not only offers a solid packet-prioritization system, but several key network enhancements as well. Deployment is understandably painstaking.
Sure, I agree IPv4 is legendary. But using it with what the internet now demands is like trying to get to the moon with a steam locomotive.
