A fake email. It reads: From: Linus Torvalds [email protected] To: [email protected] Subject: [RFC] Remove IPv4 support from kernel, effective next merge window Date: Sat, 15 Aug 2025 10:42:00 -0700 Message-ID: [email protected]
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.)

Honestly, I get this is a joke…but it unironically wouldn’t impact me, I run single stack v6, so let’s do it. I’ll grab some popcorn
Isn’t like 50% of the internet broken for you if you’re only running IPv6? It seems like so many websites , especially small ones, still aren’t setting up v6 addresses
Now that’s some April Fools trolling done right.
I forgot what day it was.
Me too. This is the only one that fooled me at first today. Ill take it. If you have to make a joke about ip addresses and the kernel to fool me, then I guess I’m still pretty sharp.
HRT :3
blåhaj :3
If we magically got rid of IPv4, I do wonder if the world would decay to a state of utter chaos like the tabloids were touting for Y2K
\Just in case you guys want to fight each other like kernel devs, and need some raccoon GIFs for that.
GIF is pronounced /ɣi:f/ by the way.God I fucking wish. I hate ipv6 but I hate this split world even more. Nothing but headaches.
It may be inevitable, but if you wonder why ipv6 has been slow to adopt, it’s because no one want to type in 32 alphanumeric digits for every single device, every time…
I’m slowly moving in the direction and have learned a lot, but in my home network, all my devices get a bunch of IPs and services seem to choose at random the IP to listen on. My ISP changes my prefix at random. Devices don’t register in DNS. So even if I use the ULA it’s a lot of fucking typing.
I also had this thing for a while where the MAC of a bhyve VM would change at boot so even the ULA changed. That fucked me for a while.
Opnsense lets me create aliases allowing me to create firewall rules, so at least that works now… kinda. But i haven’t figured out privacy extensions.
So yes, you’re right, 32 digits is a lot to keep in mind.
Just give OpenClaw unrestricted access to your system and make the AI do it. /s
I mean I did say I hate ipv6…
But seriously, I think it has more to do with it’s slightly different, easier for ISPs to just add another NAT layer or whatever instead of learn the minor differences.
Also gives them more control, and they can charge extra for open ports.
High Resolution Timers aren’t even the most controversial HRT.
I was dying with suspense wondering if he would weigh in on that.
Not really.

Based and v6 pilled.
I really gotta see this racoon gif
Finally some welcome news. I’m tired of simple easy to understand addressing.
Also, DNS is now depricated and will be removed in the merge window after the ipv4 removal. This will fix 90% of all networking problems.
The kernel doesn’t deal with DNS, that is a separate process/library
Embrace hexspeak.
Odd day for him to post this…
You did check today’s date?
That’s why I posted it.
How can anyone even be bothered doing 1st April anymore with everything going on?
What’s going on?
Were any toasters harmed in the making of this
toastpost?
