IPv6 will be inherently necessary. In the next ~20 years there will be tens of billions of things connected to the Internet, vastly exceeding the v4 limitations. The ability to have unique addresses for trillions of objects, may enable new technologies we haven't yet thought of. How about every house, or Sim character, in your own virtual reality universe having a v6 ip address? Silly, sure, so what. It's technologically absurd to stick to such a limited, primitive system as IPv4, with a mere four billion addresses. It'd be identical to arguing that we don't need more bandwidth, storage, transistors, et al. because, seemingly, we already have a lot. When in fact, every time we expand such restrictions, we discover and invent vast new technology fields. And the notion that v4 addresses should cost any meaningful sum, when we can each have a million v6 addresses for little to no cost - that makes it clear what the right direction is. Plenty should always be chosen over scarcity in computing resources. |
