False meme image that says “bad news ipv4 fans. linus torvalds has announced removing ipv4 support from the linux kernel after the maintainers of the network stack got into a fight over WHAT KIND OF HRT gives the best results. this incident will impact 5 billion people and will make 95% of all network equipment on Earth binnable.” with fake screenshots of the linux kernel mailing list a girl calling another one a slur from 4chan over HRT choices and Linus Torvalds saying he will drop IPv4 support and asking the maintainers to learn to shut the fuck up.
You must log in or register to comment.
I’m ignorant enough that I didn’t realize this wasn’t actually happening until I read the comments. My networking knowledge is piss poor haha.
Don’t worry about the network side of things. It’s open source. Before they turn everything on its head would be forked and it would be replaced.
I wish.
If you don’t use IPv6, you are behind. For me the transition was so hard, it’s a big step behind me, wouldn’t want to do it again.
I still remember my network lecturer telling us how IPv6 was the future and how we were running out of IPs back in… 1997.
That same year, during my work placement, I was introduced to Squid and all sorts of network fuckery to compensate for those supposedly disappearing IPs.
Honestly I need an AI to protect my data.
It’s too much atp
I believed it for a moment
You got me in the first half 😁
Ipv4 is simpler and therefore easier for my brain to comprehend.
I deliberately disable IPv6 on all the devices on my home network because it’s really f**n annoying when some service tries to bind to localhost but picks up the IPv6 localhost instead of the IPv4 one
IPv4 is very much not simpler. You just as used to it.
I’ve encountered way too many administrators and network admins who swear that “IPv6 does nothing but cause trouble” but the truth is, the trouble it’s causing is because you can’t half-implement IPv6. You either roll it out to the whole network or you don’t, and the longer you kick that can down the road the harder it’s going to be.
Basically too many professionals who haven’t learned a new technology since 2005 and refuse to try new things keep holding the world back
Can’t even attempt to learn it if my ISP won’t provide addresses though.
Not been able to use it to even try, but doesn’t IPv6 not have subnets at all? No 192.168.1.1 on your local network with a different public facing 85.136.52.142 (and with NAT444 you also have ISP facing 10.183.23.6). So does your ISP provide you a range of IPv6 addresses?
Correct, the ISP would assign you a /56 of public IPs that all share a prefix which you can slice and dice into however you see fit. All devices receive a publicly routable IP which your router/firewall would limit access to. So no running out of IPs ever, no network/IP collisions if you have to connect to another private network, etc.
A single IPv6 prefix has 2^64 addresses
Yes, your ISP provides you a large quantity of adresses. Not really, the adresses has several parts. Your ISP provides you with the prefix. Your devices complete the rest of the address automatically. You can also use a DHCPv6 server, but I don’t and some devices don’t support it anyway. Yes, all those adresses are globally routable, they are “Internet” adresses. You can still use locally routable adresses too if you want, called Unique local address (look it up on Wikipedia), but that requires manual configuration.
I don’t think unique local addresses require manual configuration. On linux at least, I get an
fe80::address derived from the interface’s MAC address even if there it can’t find any router. If the host receives a router advertisement, it will add a local address (the same suffix as the fe80 but with afd8b:something::/64)and the “internet”2003::.I’m not an expert and this may be just the configuration of my router, but all my linux installs automatically got these three addresses without manual configuration or issues.
That’s SLAAC not a ULA
Why can’t you just use it on your local network? Don’t need ISP for that.
I will happily enable and use it once doing so doesn’t break any of my connectivity.
I’m not managing an enterprise network, it’s just my home, but my ISP doesn’t support IPv6 so that’s one extra layer of complexity right off the hop. On top of that internal services switch which previously required no manual configuration just seem to randomly not work.
IPv6 is not going to see widespread adoption unless it can be implemented completely transparently for the end user, full stop.
IPv6 is widely adopted
I don’t even have an ipv6 address, my ISP doesn’t provide them yet. Not much to do about it then lol.
I think what those admins really mean to say is “We don’t need any of the benefits of IPv6, so IPv4 works just fine and making the large scale change is trouble.”, when you already got your DHCP, NAT, Firewall and stuff up and things do work as expected then you don’t really need NDP or SLAAC.
The issue for me is when I have it enabled and try to connect to a site that doesn’t support it fully (same thing / half assed) and the site doesn’t work properly. For home its my wife and kids that complain, when its the office then everyone complains. I get the blame for failed connections or things not working right when a fully compliant IPv6 site works just fine.
Now I am not perfect so It could be me but I have read up and learned as much as possible. No expert but I did deploy DHCPv6 in a test environment. However there is no reason as of yet to deploy DHCPv6 locally since the address space is so wide. Just saying Its possible that the issue is me but from my understanding its like the U.S.A. switching to metric. Parts of us tried it but others didn’t and thus we failed as a giant group.
I think there needs to be a big ass push and force everyone to switch as the same time. I know some of the old devices may not work however those devices have to be 20+ years by now.
Basically too many professionals who haven’t learned a new technology since 2005 and refuse to try new things keep holding the world back
If it ain’t broke…
^ the admin holding the entire world back
Imagine arguing that ‘solutions’ like NAT444 isn’t broke as fuck
Imagine arguing that ‘solutions’ like NAT444 isn’t broke as fuck
Well… yeah, why wouldn’t that be “broke as fuck”?
I always bring it up when the network is experiencing problems that they wouldn’t have with IPv6. Running out of IPs in a given scope, increasing costs of public IPs, etc.
In a local network there is no point in using ipv6.
It is interesting when you run out of ip addresses for the amount of devices you have.
So in the open Internet.
Unless I am missing something.
A couple of things that IPv6 does better for local networks is link local addressing (fe80::). and multicasting.
In IPv4, they kind of hacked something out of 169.254, but if you have more than one NIC, it pretty much becomes useless.
If you have a service designed explicitly never to be accessed over a router, then you can live in fe80:: a lot more easily than trying to do the same thing with 169.254.
Please, at least 85% of that network equipment hasn’t been updated in 30 years and they’re not about to start now.
screams in salt typhoon
IPv4 killed my parents.
Can confirm, I was IPv4
I believe it

Maybe this will move my ISP to provide IPv6.
Followup:
Truly a legend, if true
I’m glad that Linus clarified that it was High Resolution Timers. I was honestly thinking they were arguing about Hormone Replacement Therapy.
It ended up that way though
THE TOASTER WILL BE REPLACED.
Fucking legendary quote from Linus.
It’s a shame it’s fake.
do you have proof that it’s fake though
There is the rule number one of the linux kernel: “We don’t break userspace.” Linux has refused fixes for buggy behavior in the past because of this rule. This would most certainly break userspace.
Also the alt text of the original image states this is fake.
Chat, is this real?
Check the alt text.
Aw, dang it. I don’t know shit about IPv6 vs IPv4 other than how it be written, but I wanted some chaos
Is the raccoon gif real?
none of this is.
Truly a Solomonic decision.
A highly nuclear option. I hope that those developers get their act together in time.
this is a joke btw.
I noticed. But sometimes, LT can be a bit explosive, and we all know that devs can be bitches about their code. I would not put it past Linus that he actally threatens some fully nuclear option to bring some boneheads to reason.
Well I’m not going to switch away my perfectly functional mesh routers that uses IPv4 as using IPv6 on a local net that I may sometimes need to type in manually is rather stupid. And that would also bin my routers, so I’m not doing that either.
Oh well, I guess it’s been fun guys, no more Linux for me due to potential future security issues.
You will do as you’re told!
Yes daddy!
Do you want to play a game?
I think it is more likely that 95% of network equipment supports IPv6
Except whatever brings internet to my apartment apparently
Your ISP needs to setup IPv6 which isn’t trivial to do from scratch.
What provider is it?
Mine is Quantum Fiber, a sister of CenturyLink. CL has it, apparently QF doesn’t. Or at least not natively, rather 6rd. And then possibly not on the modem they installed? At any rate, I haven’t been able to find anything online.
It should have IPv6
Odd
🤷🏼♂️ When I had CL I could turn it on by enabling 6rd and it worked as expected. When I moved across town and got QF, their instructions didn’t account for it and following the same online instructions for CL don’t work. Others online seem to not have had any luck either, but some people’s comments make it sound like it’s the modem.
I’m on one of the regions of fiber that CenturyLink spun off to a private equity firm a few years ago. Zero IPv6 support here
Maybe this is the push that finally makes IPv6 go mainstream!
Nah, IPX is gonna take over.
What’s IPX?
https://en.wikipedia.org/wiki/Internetwork_Packet_Exchange
Internetwork Packet Exchange (IPX) is the network-layer protocol in the IPX/SPX protocol suite. IPX is derived from Xerox Network Systems’ IDP. It also has the ability to act as a transport layer protocol.
The IPX/SPX protocol suite was very popular through the late 1980s and mid-1990s because it was used by Novell NetWare, a network operating system. Due to Novell NetWare’s popularity, IPX became a prominent protocol for internetworking.
(Just to be clear, IPX is not going to take over, and my above comment was intended to be humorous.)
Let’s fire up a token ring!
(Thanks for the info)
Just got to wait your turn to get the packet
I only got the joke due to starwars pod racer, thankyou pod racer! The ancient pc version allowed you to play upto 8 people on a local network, but box requirements states it needed to be IPX. I have a dream of making a 8 player VM machine in one portable box for parties
It’s IPv10, which binds IPv4 and IPv6 together (4+6=10), sometimes known as Dual Stack.
What’s IPX?
I once asked my college professor of computer networking to explain IPX to me and this was the response I got.
What’s a Gigahon?
