That's an interesting idea. I don't know if the FTC has the authority to do so under the current powers given to it by Congress, and I don't know if I'd like the precedent of them trying without Congress so delegating that power. I'd be totally willing to discuss Congress delegating them said authority.
That you call global IPv4 addresses to be a critical resource is extremely odd. If I go to prudential.com or to another insurer's website, the IP delivery addressing protocol doesn't affect competition.
A user doesn't really see any difference when traffic gets delivered over IPv6 instead of IPv4, so the scarcity of the global IPv4 space is meaningless compared to the incredibly vast usable size of the global IP space.
So offering any service just on IPv6 makes no sense in 99% of the cases. You can use if for some internal cases, if you can be sure that all your users have IPv6 wherever they happen to be.
If you are cloud provider and cannot offer your customers as many public IPv4 addresses as they want you are out of business.
Using it doesn't. But having a pool of 200 times more than the next competitor does. I'm not sure whether according to the letter of the law. Courts would decide that a decade later if any administration went to court. But certainly in the spirit of free competition.
That's if you can define IPV4 as a critical resource. But because anyone can assign any IPv4 address to anything and advertise it with BGP, it can't fit the definition of that.
Can it be defined as property? I could make a Internet The Second using isolated networks and advertise whatever I wanted. It's not like digital movies and music where it's defined as property under copyright law because it's a creative work.
This is the same as saying no one can own a Disney character because anyone can draw it at home. Or no one owns songs because you can freely transmit them between devices you own.
People still own those things in most jurisdictions around the world.
Yeah I don't have much any problem with doing CGNat. We need to get the ISPs to do IPv6, and we need to penalize AWS when a customer chooses to do IPv4 only. (They will pass on the fee, which is just fine easier than going after the customers directly.)
