Today in our newest take on “older technology is better”: why NAT rules!
I can remember an up, but would never an ipv6
Slightly related to the issue of remembering addresses, I think the main issue is with the fact that local nameservers are pretty much non-existent if you’re not running OpenWrt or OpnSense. Which is shameful because the local nameserver is an amazing quality of life tool.
Also the fact that officially there are no local TLDs except for “.arpa” while browsers won’t resolve one word domains without adding http://
And don’t get me started on TLS certificates in local networks… (although dns01 saves the day)
I’ve taken to using .here (or .aqui, “here” in Español, much harder to match outside) as alternatives until something better comes up.
Ideally I’d use .aquí, correctly with the diacritic, but DNS doesn’t seem to support even the basics of Unicode in 2024.
Well, there is Punycode, which, if I understand correctly, is a layer before DNS, which translates a Unicode string into a DNS-compatible ASCII string.
I don’t actually recommend using that, though. Every so often, the ugly ASCII string shows up in places, because Punycode translation isn’t implemented there. Certainly increases administration complexity.
I would love to start using ipv6 but my ISP decided that their devices won’t support prefix delegation because “nobody uses ipv6 and nothing works with it”
I feel like I could learn Dutch, my English is already broken
IPv6 = second system effect. It’s way too complicated for what was needed and this complexity hinders its adoption. We don’t need 100 ip addresses for every atom on the earth’s surface and we never will.
They should have just added an octet to IPv4 and be done with it.
Every time there’s a “just add an extra octet” argument, I feel some people are completely clueless about how hardware works.
Most hardware comes with 32-bit or 64-bit registers. (Recall that IPv6 came out just a year before the Nintendo 64.) By adding only an extra octet, thus having 40 bits for addressing, you are wasting 24 bits of a 64-bit register. Or wasting 24 bits of a 32-bit register pair. Either way, this is inefficient.
And there’s also the fact that the modern internet is actually reaching the upper limits of a hypothetical 64-bit IPv5: https://lemmy.world/comment/10727792. Do we want to spend yet another two decades just to transition to a newer protocol?
you are wasting 24 bits of a 64-bit register
You’re not “wasting” them if you just don’t need the extra bits, Are you wasting a 32-bit integer if your program only ever counts up to 1000000?
Even so when you do start to need them, you can gradually make the other bits available in the form of more octets. Like you can just define it as a.b.c.d.e = 0.a.b.c.d.e = 0.0.a.b.c.d.e = 0.0.0.a.b.c.d.e

If you’re worried about wasting registers it makes even less sense to switch from a 32-bit addressing space to a 128-bit one in one go.
Anyway, your explanation is a perfect example of “second system effect” at work. You get all caught up in the mistakes of the first system, in casu the lack of addressing bits, and then you go all out to correct those mistakes for your second system, giving it all the bits humanity could ever need before the heat death of the universe, while ignoring the real world implications of your choices. And now you are surprised that nobody wants to use your 128-bit abomination.
You’re not “wasting” them if you just don’t need the extra bits
We are talking about addresses, not counters. An inherently hierarchical one at that (i.e. it goes from top to bottom using up all bits). If you don’t use the bits you are actually wasting them.
you can gradually make the other bits available in the form of more octets
So why didn’t we make other bits available for IPv4 gradually? Yeah, same issue as that: Forwards compatibility. If you meant that this “IPv5” standard should specify compulsory 64-bit support from the very beginning, then why are you arbitrarily restricting the use of some bits in the first place?

All the 128 bits are used in IPv6. ;)
