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 think having both is nice.
Linus did a follow-up: https://⚧.fm/notes/abh00crrs1gcja8q
Fine lol
Real
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.
My dream. IPv6 adoption would skyrocket to a degree unimaginable and those who don’t want to, will fall behind unless they move their asses and learn.
ipv6 is great for public networks/ wan or extreme large nets. but for a small local net, ipv4 is so much easier if you need to access a single device. if ipv6 is parallell too, great but I hope ipv4 wont be disabled/ non existens in the future bc of this
I need to make sure you know this is a joke
I need to be told as well.
Tell me. Tell me now, or I torch my fiber modem!
As long as IPv2 support remains intact, I’m good.
/s
As a modest proposal, let’s just kill anyone who disagrees. These troglodytes had long enough time to get on speed with the world and human progress cannot further afford individuals unwilling to adapt.
Renewal! Progress! Electrification!
Moderates nowadays be like:
Followup:
THE TOASTER WILL BE REPLACED.
Fucking legendary quote from Linus.
It’s a shame it’s fake.
I’m glad that Linus clarified that it was High Resolution Timers. I was honestly thinking they were arguing about Hormone Replacement Therapy.
Given the demographics of Linux devs, it probably would be the latter.
I know! It seemed totally plausible! There is a very odd discrepancy between that and the general population.
It ended up that way though
Chat, is this real?
I’m sure he emails the kernel he works on regularly
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
A highly nuclear option. I hope that those developers get their act together in time.
this is a joke btw.
Is the raccoon gif real?
none of this is.
Truly a Solomonic decision.
Thanks for the alt text & transcript in OP. It’s missing here, though.

Subject: [RFC] Remove IPv4 support from kernel, effective next merge window
Date: Sat, 15 Aug 2025 10:42:00 -0700
Message-ID: <20250815-drop-ipv4@linux-foundation.org>Hey folks,
After yet another deeply technical and entirely calm discussion about HRT (High-Resolution Timers) that somehow devolved into 200+ replies, personal insults, and at least one GIF of a raccoon, I have decided it’s time to take drastic measures.
Effective next merge window, we will be removing IPv4 support from the kernel. This will both (a) resolve the maintainers’ scheduling disputes, and (b) force the world into the IPV6 utopia we were promised back in 1998.
If you need IPv4 after this point, you can either:
- run an ancient kernel from before the change (good luck with the bugs), or
- rewrite your applications to use IPv6 and learn to love colons in your addresses.
Yes, I realize this will break roughly *everything *.
No, I don’t care. I have already switched all my machines to IPv6-only, except for the toaster, which unfortunately still insists on using a 192. 168. x. x address. The toaster will be replaced.If you disagree with this decision, I suggest you take it up with the HRT maintainers. But please keep it civil this time. (Or at least keep the raccoon GIFs under 1MB.)
- Linus
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 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…

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.

Why?
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 serverif 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.
Something needed to happen here, we’ll see if even Torvalds has the power to kick massive telecom and consumer electronics conglomerates in the butt. It’s been too long.
- My fiber provider started an early rollout of IPv6 like a decade abgo, and it’s been stalled out ever since.
- I’m still seeing new consumer electronics being sold even though they’re IPv4 only.
I still miss IPv5
For real, what the hell happened to IPv5?
The same as winamp 4.
We don’t talk about IPv5.
About time too.
I’m kind of weirdly horny for Torvalds making unilateral decisions about long running controversies? Tell me what standards are best kernel daddy.
Maybe next he can ban tabs and ‘\t’ from Linux? Everyone indents with spaces now, debate over.
I’m sorry, WHAT? SPACES???
You ever find yourself lost for half a day indenting 1000+ lines of code in a random script you opened because the original developer was lazy?
I’d never do such a thing manually. I’d toss it in a formatter and call it a day.
No
(As a lover of mixed-style and chaos in general, I picked what seemed like the “normiest” option for maximum impact, haha)
Picking the wrong option can be the way to go, sometimes. I used to pronounce it gif, but I switched over to gif instead, and now it’s just how it be
So which is the best?
IPv6 is 50% higher than 4, so obviously it’s better.
No, IPv6 is in 6th place. We need to find IPv1st.
