JVestry,<p>1. You can't count IPs and internet users, and conclude 2 IPs per user. That betrays a vast misunderstanding of the nature of the internet.<p>2. Unless you have a very odd ISP, you and all of your neighbors are using public IP addresses. There are serious technical and performance challenges involved when ISPs use NAT to hide their customers from the internet. It breaks a great number of services that users expect to just work. In short, NAT is not a magical de-multiplier.<p>3. The authority that gives out IP addresses already forces companies to justify their use. There is waste, but not so much that this is a problem we can simply "manage" away.<p>4. There are rules against selling IP address allocations. So your "free market will fix it" argument is dead in the water.<p>5. Most routers can "publish" an IPv4 and IPv6 address? What the hell does that even mean? That's garbage nonsense talk.<p>In conclusion, your blog post is way off the reservation. Factually incorrect, complete conjecture, and just plain made-up gobbledeygook. It's obvious that absolutely no research was done before publishing this. For being so offensively wrong and poorly written, I'm flagging this submission.
