I'm sorry but how? We have appliances with dockerfiles, micro containers for remote controls, extensive botnets of virtual machines, centuries in the future when we have expanded into the solar system and trillions of humans all having millions of unique applications with addresses, it's inevitable to hit a finite number. When every square meter of smart road has an routable address; we will likely be rewriting networking anyways. The only players pushing IPv6 transition are networking companies because a new standard requires new hardware.
