Ford has multiple design centres in different countries plus a lot of subcontractors who may need to connect to stuff from outside. I can believe that they are using a large part of an /8.
And normal people and smaller companies need their addresses even more.
There are a ton of /8 still assigned to companies that don't need them. Ford, GE, IBM, AT&T (x2), Xerox, HP (x2), Apple, MIT, CSC, Eli Lilly, Nortel, Prudential Insurance, DuPont, Cap Debis, Merck, SITA. All of those can return their /8. That's 18 /8 potentially available. And does the DoD really need 12 /8's? I get that they want to network every person, gun, ship, tank, truck and plane. But none of those need to be…
Can those companies sell their IPs on the open market when the normal pool has run out? Is that allowed?

The main argument for migrating existing websites to IPv6 in the near-term is merely to aid the policy goal by showing "Hey! IPv6 is in actual use!". On the technical side, there are various transition mechanisms that can ensure even "IPv6-only" clients will be able to communicate with most legacy IPv4 services for years to come. HN is not holding up progress.
No, such a thing does not exist. At least not automatically. There are stories[1] about large corporations getting complaints from end customers in Asia about not being reachable - and it turns out the customers only have IPv6. IPv4 FAIL. (Note: APNIC ran out of IPv4 addresses more than two years ago [2], and has had rapid internet expansion in the mean time. Asians are heavy IPv6 adopters.) Such a thing you imagine…

Reassigning some ipv4 IPs on a handful of corporations' internal networks would dwarf the cost of upgrading the entire internet infrastructure to ipv6? I get assigned a new ipv4 IP by DHCP every time I reboot my computer. And you should hear the infrastructure people at my ISP and workplace and university squeal when you ask them about ipv6 - far too much work, they say, no plans on the horizon.
>I get assigned a new ipv4 IP by DHCP every time I reboot my computer. Sure - from your router's subnet. The route to that address still goes to that router. There's no BGP update to propagate, no routing table entry to add to every router on the internet. I mean, why not assign every IP address individually? That way we'd be fine for up to 2^32 internet-connected devices. Every router would just have to store all 2^…

This could be a fortunate investment that will make them lots of money. Give it back? I doubt it. Sell it back? Profit.
> This could be a fortunate investment that will make them lots of money. Apple has ~$150b in cash reserves. Selling a /8 would amount to nothing on their balance sheets, whereas owning a /8 can have invaluable uses.
When IPv6 is fully implemented, an IPv4 /8 will be essentially worthless. Reasonable people can disagree as to when that day will come, but it will come. It's probably not that far off.
Why not sell it or suballocate it while you can still get money for it?

Right. How much code is out there that looks like if(recv.ip.contains("2.") { //well we know that they're from X co. }
I'm not sure if you are being sarcastic. I'd bet a lot.
Also, I'm surprised no one called me out on the typo and bug in my code :)

Not sarcastic. There's a ton of code like that. I've seen it. Also, I'm surprised no one called me out on the typo and bug in my code :)
Bah. All this IPV4 "exhaustion" stuff can be simply solved. Almost overnight. Right now, most of the space is underused and simply being hoarded. Want to free up 90% of the IPs? Easily? Then charge for them!!! If MIT had to pay $1/mo for each IP address ($16 million per month), it would immediately give most of them back. If MIT had to pay $1/year for each IP address ($16 million per year), it would immediately give…
I hate to break it to you, but everything you're using right now to send this information was arguably designed by nerds.

No, it does not sound like the parent doesn't know the difference between public and private IP addresses. What it sounds like is that you expect Ford to take the time and energy to renumber their entire network just because they presumably don't need a /8. And while it's true that they probably don't need a whole /8, making them renumber is ridiculous.
I just knew someone was going to totally change the argument. The argument I was replying to was that they use 16.7MM addresses. I proved that there is no way they use 16.7MM addresses. So either you didn't read the original argument, or you just like to argue so you are now changing the argument. In either case, I'll bite. Nobody is asking Ford to be altruistic about this. Right now their /8 has some value. They hav…

No, the argument you were replying to was that they make use of the entire address space, which does not at all require every address to be in use. For example, each of their /16s may be used for a different organization, product, or location, and it's likely that many of the /24s for each /16 are further logically divided for organizational and routing purposes.
The idea the original claim was trying to disagree with was that all the network infrastructure in place was using a monolithic /8 with no logical divisions. Specifically, "them" in masklinn's comment was referring to "blocks", not addresses.
> Some of those companies uses their blocks to make every machine in their network globally routable, they don't "need" them but they do use them and they're part of their network architecture.

Legally it's an allocation, not ownership. The registry could simply revoke your allocations if it caught you selling them (though whether it would is another question).
Frankly, the only way to truly transfer an IP block between companies is to have one company buy the other, then the IP addresses can be reallocated to the new owner. You can't just transfer an IP block to another entity according to ARIN's registration agreement.
