- Understand the difference between a joke and an insult.
- Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
- Don't get baited into back-and-forth insults. We are not animals.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
- Bigotry of any kind will not be tolerated. This is an LGBTQ+-friendly community -- if that is a problem for you, you should leave.
3. Post Linux-related content
- Including Unix and BSD.
- Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of
sudoin Windows. - No porn, no politics, no trolling or ragebaiting.
- Don't come looking for advice, this is not the right community.
4. No recent reposts
- Everybody uses Arch btw, can't quit Vim, <loves / tolerates / hates> systemd, and wants to interject for a moment. You can stop now.

But I doubt your momma can read that.
Mine can't. She's not interested in binary or hex, despite my efforts to convince her how fascinating the topic is.
Could we have an IPv6 one? Itβs 2026.
no.
But it's not possible to do this joke since ipv6 does not have subnets.
What? There's no way that's right, right?
Well, sort of.
You can divide up IPv6 addresses as you like.
But ... there's so much space there that they are typically just divided in half.
64 bits of subnet (aka routing prefix) + 64 bits of host address.
They play a lot of games with the first 12 or so bits to say what kind of network it is, and the rules change a lot for multicast and other address types.
So its not a subnet as you know it, but it still is.
/24
/128
um ... that's wrong.
why?
Two reasons.
You were responding to someone who offered a /24 as a subnet.
There are 32 bits in an IPv4 address. /24 is 255.255.255.0.
So they were wrong too in reference to IPv6, but at least they were making sense.
You responded with /128, which is the full range of the IPv6 address.
That would be like the prior poster saying /32 aka 255.255.255.255.
There's no usable range there.
And, see my post above for the rest of the breakdown, but you were looking for /64.
That's way too broad, for protection it should probably be 255.255.255.254
255.255.255.252 for your significant other
I think you both have an off-by-one error there. Itβs /32 for one device and /31 for 2 devices (selected by the last bit). It feels wrong to have /32 be the entire adress space btw.
I don't need a gateway or broadcast to talk to my SO just .0 for me and .1 for them
Just use IPV6
/64
how is this a Linux meme?
its hardly even a meme.
He runs allpine btw
A subnet mask mask!
I'll get your coat
