I’ve been hearing about ipv4 running out and the need to move to ipv6 for so many years/decades, but it keeps not happening. I’m wondering if anything will change in my lifetime.

ipv6 is _the_ mobile and india internet, mostly. iphones are v6 only as are indian consumer connections.

> iphones are v6 only

Are you sure about this? Do you have a link with details?

If I disconnect from WiFi and use the SIM card currently in my iPhone, and I go to one of the websites that tell me my public IPv4 and IPv6 address it shows that the mobile internet connection I have with this SIM card is IPv4 only.

I host a few video game servers for my friends and love the fact that I can say my easy to remember IPv4 address aloud whenever they forgot it. I have an IPv6 address but haven't bothered memorizing it or giving it out because it would just be more hassle.

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.

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.

Well again I’m not a network expert but perhaps we could look at the 240.0.0.0/4 reserved for future use block and add more address bytes in the payload or something. It’s not going to be elegant but IPv6 is kinda elegant and failed.

This is the most hilarious "I don't understand anything about the problem, therefore I don't understand how it's hard" comment I've seen this week. > perhaps we could look at the 240.0.0.0/4 reserved for future use block What's the current rate of v4 address space consumption? How long will this block last? > and add more address bytes in the payload or something. This is, by definition, not backward compatible.

I may not have been clear enough in my suggestion. The idea would be to use this unused block as a special block. Not to fill it up with normal IPv4 allocations.

See my suggestion as some kind of NAT-PT at scale. With a better marketing name and user experience.

The problem is indeed hard because no one manage to find a solution at scale since 3 decades.

Not OP nor a recognised network expert but here is my suggestion: IPv10. The next IP version number that is unassigned, that is conveniently 4+6. Basically something that is not breaking compatibility with IPv4 and doesn’t require those dual network stacks nonsense.

How do you not break compatibility with IPv4 while also getting more bytes in the address?

Maybe just don't? Let it be IPv4 with more bits, the software is already there so dual stacking isn't so bad, adoption might actually be quick if people didn't have to learn much to implement it.

If one has to go through the pain of changing everything why not make sure one doesn't have to do it again any time soon? Also having 64-bit for the network address (and 64-bit for the device) does have certain benefits that make it easier to use than shorter addresses in practice for a single entity, since one can hierarchically model the network and do things like : : . So even in absence of DNS one doesn't quite h…

But ever since privacy extensions, that's not how IPv6 is allocated, right? Each individual system is supposed to get a /64. Your household should actually have a /56 or something crazy like that, which few ISPs actually do. SLAAC doesn't even work if it doesn't have it's own /64 per host, I believe.

It is. A typical enterprise might get allocated a /32, which gives them 32-bit to nicely design their network and give 64-bit to each individual network where devices are connected.

A typical ISP will get allocated a much larger allocation like a /20, which allows them to allocate a /56 for each of their customers while still having a few bits to play with. But all starting with the same prefix.

With IPv4 you will have many separate fragmented networks that have no numbers in common. And this will only get worse over time.

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...

IPv6 is so awful. We need a re-do.

The cost to own an IP is about $45. But that is almost entirely a one time cost, you can rent an IP for well under $10 a year

How do you do that? I'd like to buy one.

You need to buy a minimum of /24
