No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

I know that IPv6 was created in 1998 as a future-proofing, to make sure that there will be enough IP addresses in the works for large networks. IPv4 uses 32 bits and is represented with denary (0-9) while IPv6 uses 128 bits, so there are far more possible addresses, and it is represented using hexadecimal (0-9 then A-F).

What I'm wondering is why IPv4 is still so common, even though the number of devices connected to the internet have skyrocketed with more computers, laptops, smartphones, game consoles, embedded systems, etc. all connected! If it was thought that there would be too few available addresses in 1998, surely that has to be a bigger problem in the modern day?

Additionally, why didn't IPv6 replace v4, even after nearly three decades of existing? Is it a technological limitation, cost, or something else?

And online I see many sysadmins online (!) complaining about IPv6 being more difficult to work with. Is this because the addresses are harder to remember, are adaptations of the protocol by manufacturers all different (similar to USB-C), or is there some other problem with IPv6? Or is this a case of a loud angry minority, especially in chat forums where people tend to have more polarised views?

Many devices do support IPv6, but it's not universal like IPv4, despite the standard existing since 1998 and having many advantages. Why is this?

One of the main issues I think is holding IPv6 back is that we keep needing to memorize IPs and type them by hand. 192.168.0.16, 172.16.0.0/12, and 10.0.0.0/8 are easy to remember, and usually it's just the last number that's important, anyway, because we all use 192.168.1.0/24 by default.

But then IPv6 comes along with /48 prefixes and endless numbers to read, analyze (same subnet? typos?), memorize or write down. Ain't nobody got time for that.

IPv6 would have to integrate some sort of DNS resolver on a network level so that people can work with computer names. That would make the hostname actually relevant and not have every Windows be called DESKTOP-W38D6M5P. If you already have a separate DNS service, it's only the registration step that has slightly more friction, but still.

E: I guess you could argue that it's a UI problem. IPv6 has neighbor discovery and the UI can just show a list to choose from. Still no hostnames, though. Is configuration part of a layer's responsibility?

because we all use 192.168.1.0/24 by default.

This is a bigger deal than you may think. Those of us stubborn enough to use one of the other defined internal network ranges already hit more obstacles than we should, and that difference should be trivial to non-existent.

For me the latest is a smart home device that hard-coded 192.168.1.x, so I am not able to connect it to my network

[–] False@lemmy.world 2 points 4 days ago* (last edited 3 days ago)

Most network devices can have multiple IPs. Assign 192.168.1.1 to your router (in addition to your normal one) and it should probably start routing traffic to that device

You should see the unfinished proposal for ipv8. The authors think yes to a large degree, though not how you're thinking.

https://www.ietf.org/archive/id/draft-thain-ipv8-00.html

I wish they would say that IPv8 is a proper superset of IPv4 and not that IPv4 is a proper subset of IPv8, just because they're building IPv8 on top of the existing IPv4.

[–] mech@feddit.org 2 points 4 days ago

This sounds like they realize v6 sucked and want to build something you can just plug into a v4 network.

Without a central server, hostname resolution is handled with mDNS. It is designed to do exactly what you're asking: allow you to resolve hostnames to IP addresses without a DNS server. A node simply broadcasts (multicasts) a request for who has a name, and whichever node has it responds with their IP.

[–] Randelung@lemmy.world 1 points 3 days ago

Whenever I've come across mDNS it was unstable and not installed. Bonjour was distributed with iTunes and sucked (15y ago). I could see mDNS supplying additional info for a configuration tool, but the IP layer remains reliant on IPs.

What bugs me is that IPv6 has built-in neighbor discovery that almost does what mDNS does, which could just have included a hostname... It's a replacement for ARP and only ARP.
