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.

Maybe this is the push that finally makes IPv6 go mainstream!

    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.)

    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

    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.

    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

    A highly nuclear option. I hope that those developers get their act together in time.

    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.

    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 the fd part being the same for all intranets rather than 192.168.1.10 with 192.168 generally 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>.local thanks to mDNS. Avahi has been doing this for... 20 years I think?

    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 server

    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?

    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.

    πŸ€·πŸΌβ€β™‚οΈ 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 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

    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.

    Just remember, a lot of trans people have internalized transphobia - that doesn't excuse it, but it's important context that a lot of this is self loathing.
