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.

Followup:
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
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
I’m sure he emails the kernel he works on regularly
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.
Truly a legend, if true
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.
Do you even DNS?
No. But if this is true (which I do doubt completely, Linus can’t be this dumb to singlehandedly cripple his OS), this should also affect every intranet address.
The current description of IPv6 intranet is just ridiculously dumb anyway. Should I want to ssh into a local device, I’ll have to type in for example
fd9e:9aa0:c00f:1::a, with only thefdpart being the same for all intranets rather than192.168.1.10with192.168generally always being the same.Edit: wait… Are you telling me to set DNS redirects on all my local devices? Yeah, that’ll work, but why the even…
I don’t think I’ve entered an IP address for a local device in years. Everything is accessible using
<hostname>.localthanks to mDNS. Avahi has been doing this for… 20 years I think?Cool. My mesh doesn’t have that though (I think?). But admittedly that’s a tangent. If IPv4 ever depreciates, I’ll have to toss my mesh anyway.
Pihole automatically adds clients that get an IP from its DHCP component. All my clients are server.local, client1.local, tv1.local, etc. So I can use their DNS name everywhere.
Even if it don’t want to use pihole(why?), you can edit the SSH config and add addresses for each host so you can just type
ssh serverOr I could also just edit
/etc/hostsif I’m just accessing stuff from my computer. I mean, I understand there are ways around this pain point. But, on IPv4, I wouldn’t have to do anything? Can’t really beat that, right?
I think ipv4 for internal networks is fine.
wait… Are you telling me to set DNS redirects on all my local devices? Yeah, that’ll work, but why the even…
What do you mean by that? I’m pretty sure people are telling you to run a DNS server and set up entries for any clients you want to regularly connect to.
with only the fd part being the same for all intranets
Why?
if this is true (which I do doubt completely
I really want to believe that you doubt it completely.
Yeah, I really have put too much time into replying to all these based solely on a hypothetical. But I did learn something from all these comments (technical something, not me being an idiot), so it’s all good.
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.
Maybe you shouldn’t treat random images you find on the internet as factual until you can verify the content.
I would have looked it up if the comments didn’t speak about it already. Don’t worry, I’m not a troglodyte when it comes to actually having critical thinking skills.
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.
A major ISP in the UK still doesn’t have any IPv6 support :( https://www.havevirginmediaenabledipv6yet.co.uk/
I’m on Spectrum in the US and their “support” is somehow worse than just not having IPv6. Tons of dropped packets, shifting IP address ranges, and overall a lot of headaches. Tried everything I could to sidestep the issues but there was nothing doing. Eventually I just disabled IPv6 and the issues went away. Maddening.
They give 2 options: “Sign the petition” and “Tweet them!”, but you could also just en-masse “Switch providers” and make them rethink their strategy.
I wonder if that site pings an IPv6 address on the virgin network and updates the output automatically based on the ping result.
I still don’t have an IPv6 address over 4G with Vodafone. I want to run a web server on my phone, isn’t this a normal use case? Nat444 makes that pretty difficult, just let me use IPv6!
Cabled from Vodafone is not much better, ip6 does auto configure from the router with a local address, so it at least supports it. but no routable ips yet.
Actually on someone else’s network right now and think it’s cabled Vodafone and I do have IPv6. Only got android to play with right now though, apparently Vodafone are tight bastards for the range of addresses you can get.
Edit: version of Android I am on only let’s you set a static IPv4 address, what a shit operating system
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.
I tried IPv6 only (with NAT64) and Steam didn’t work because it had IPv4 addresses hardcoded :(
I always hard code IPv4 addresses. Load balancing and DNS resolution are an admission of weakness.
(This is sarcasm. WTF Steam?)
You got me in the first half 😁
Well, I guess I would move back to Windows and try to find ways to block any IPv6 connections.
I believed it for a moment
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.
I need to inflict this reply upon others. It is so gloriously cursed out of context. And in context too.

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
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
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.
I don’t even have an ipv6 address, my ISP doesn’t provide them yet. Not much to do about it then lol.
You can maybe change ISP
I wish I could but I’m afraid it’s not possible at this address and it’s not something I’m going to move for
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.
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?
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.
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.
Why can’t you just use it on your local network? Don’t need ISP for that.
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…
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.
“IPv4 is running out of IP addresses so therefore every local network needs to move to IPv6” is a full clown move.
First of all, enterprises usually have at least one public IP (the one I work at right now has more public IPs than they have server VMs)
Secondly enterprises have big enough and complex enough networks to see other benefits of IPv6. For example IPv4 has some problems when broadcast domains are too large, so your internal network sizes are artificially limited when following best practices. Without private networks you don’t have to worry about IP collisions between different private networks that you have to route between (comes up more than you’d think!) etc etc.
Please, at least 85% of that network equipment hasn’t been updated in 30 years and they’re not about to start now.
I wish.
IPv4 killed my parents.
Can confirm, I was IPv4

Can we just treat this as real? Post it everywhere. You know in a sort of “alternative facts” / flat earth sort of way. So maybe the planet finally moves on from ipv4.
The Earth is as Flat as my wife!
Go ahead, argue I’m waiting…
I have a feeling, a lot of people willing to move to Linux are already open to trying out IPv6 when they get the time.
Pity my old router only bridges IPv4 and only does IPv6 with NAT (or maybe I just couldn’t understand the interface).
