EU have enough influence to do to IPV6 what it did to USB in iPhones.

It's harder to prove consumer harm with something as abstract as IP addresses, and there's a bunch of other pieces that make this much less unlikely, such as the fact that USBs already become obsolete and need to be replaced, so you're just shifting the replacement cycle.

They don’t need to prove consumer harm to pass laws.

You'll need to become a member of one of the regional Internet route registries, like RIPE or ARIN. Then you can buy, say a /24, and transfer it into your RIPE/ARIN account. Now you have your own IPv4 range. And you can start for example start to use it for your own servers. To do so you need to "announce" this new /24 to the internet, using a protocol known as BGP. You can do that yourself, using a router, assuming…

> To do so you need to "announce" this new /24 to the internet, using a protocol known as BGP. You can do that yourself, using a router, assuming you have an Autonomous system number (AS). Is this how BGP hijacking is done?

Technically, yes.

But good ISPs filter the prefixes their customers can announce to only those they actually own.

Then you have shitty providers that dont do it, and thats how you get BGP hijacking.

And you cant do this just from any connection, fyi.

You will need a datacenter, cloud host or residential ISP that actually allows you to peer with them and announce routes. This isnt a standard thing you get just by being a customer.

Can we go back in time and hit the designers of IPv6 upside the head? The decision not to make IPv6 backwards compatible, the belief that a beautiful new standard could magically replace something already so widespread... "Naive" is an inadequate word. We are still futzing with the transition 3 decades later, with no end in sight. Grrr, grumble...

Also, correct me if I'm wrong, but didn't they make the smallest subnet have 64k addresses? I remember a networking teacher say that by that point just ARP traffic will have long killed the subnet.

This is even better: game.latticeanimal.net. 3600 IN A 1.2.3.4

I don't know a single gamer who rented a domain for private use. In fact, I would argue than the hassle of setting one up is the reason why Hamachi got popular back then. You don't have to bother with knowing any technical stuff, just download a software, share a code and play.

Hamachi was popular back in the day because it meant you didn’t need to forward ports on your router. (Something that still confuses some of my friends).

just checked again on an iphone se, 1st-gen, ios 15.x on t-mobile reseller in germany: actually there is a v4 default route on the wwan-interface that appears to be a p2p link (192/32) probably to a cgnat. besides 127/8, there are a only v6 routes, a lot of them.

how do you check the routing table from the iphone? a jailbreak? some app?

Hurricane Electric Network Tools can do it.

Its an app.

I would hope that the migration would be more than "much further along", I'd have hoped it had been completed, like a decade ago. > is based on the same fundamental misunderstanding that one somehow can extend IPv4 in a way somehow, but remain compatible with IPv4-only clients I'm not a network eng…

I have yet to read any IPv6 alternative that can theoretically work or is not just IPv6 in disguise (or something that is implemented in IPv6 in a slightly similar fashion). It may sound like a great plan as long as one doesn't look too closely at the details. IPv4 has fixed 32-bit addresses and one cannot cram more than 32-bit of information into a fixed 32-bit field. But one would need to do that for it to be forwa…

I don't feel strongly about it, but my reading of the complaint is that the implication is it should've been something like an address in 240.0.0.0/4 plus more bits. Then to IPv4 it looks like a reserved for future use address (and we declare we're done with IPv4 now, there will be no (other) future use) but to (this hypothetical variant of) IPv6 it's a longer address.

I think what annoys people is everything else that changed with it, if DHCP (I know), subnets, NAT if you wanted it, etc. was all just the same, if the model was the same the IPs were just longer now, that they wouldn't really complain.

I'm not even sure it would be necessary to put it in unaddressable v4 block, since it would be too long and a different version anyway. Obviously people have thought about this a lot more than me so know a lot more about it, I'm not naïve about that.

Lol, I'd like to send this to DJ Bernstein, let him know that random Internet commenter thinks that one of his most well-known essays "must be a deliberate troll." Glad HN doesn't support emojis, not enough facepalms it the world for this one.

Bernstein is known for being very... opinionated.

For example his Qmail was conceptually a very well designed email server but the email standards kept evolving and I'm fairly sure at some point he just said "Qmail is feature complete and secure, no more new features and patches". Like, what? It's networked software, that's not how any of this works.

DJB's brilliance at some things doesn't make them immune from saying very silly things about other things.
