Don't bother promoting IPv6 as "the future". It's never going to be the default. (feddit.nl)

Basically what the title says. Here's the thing: address exhaustion is a solved problem. NAT already took care of this via RFC 1631. While initially presented as a temporary fix, anyone who thinks it's going anywhere at this point is simply wrong. Something might replace IPv4 as the default at some point, but it's not going to be IPv6.

And then there are the downsides of IPv6:

  • Not all legacy equipment likes IPv6. Yes, there's a lot of it out there.
  • "Nobody" remembers an IPv6 address. I know my IPv4 address, and I'm sure many others do too. Do you know your IPv6 address, though?
  • Everything already supports IPv4
  • For IPv6 to fully replace IPv4, practically everything needs to move over. De facto standards don't change very easily. There's a reason why QWERTY keyboards, ASCII character tables, and E-mail are still around, despite alternatives technically being "better".
  • Dealing with dual network stacks in the interim is annoying.

Sure, IPv6 is nice and all. But as an addition rather than as a replacement. I've disabled it by default for the past 10 years, as it tends to clutter up my ifconfig overview, and I've had no ill effects.

Granted I have very simple requirements, so It does seem pretty easy, except

  • there are still too many devices that don’t support it
  • too many ISPs don’t support it, including mine

So switching to IPv6 means running dual stack and setting up a tunnel, and I probably need to relearn firewalls. I’m not sure any of those are very difficult but it’s enough, especially since there’s no clear win here

If Matter-Thread ever gets off the ground that would help: most of my newer IPv4-only devices are home automation so switching to an IPv6-based protocol should finally make that happen

Welcome to the Unpopular Opinion community!

How voting works:

Vote the opposite of the norm.

If you agree that the opinion is unpopular give it an arrow up. If it's something that's widely accepted, give it an arrow down.

Guidelines:

Tag your post, if possible (not required)

  • If your post is a "General" unpopular opinion, start the subject with [GENERAL].
  • If it is a Lemmy-specific unpopular opinion, start it with [LEMMY].

Rules:

1. NO POLITICS

Politics is everywhere. Let's make this about [general] and [lemmy] - specific topics, and keep politics out of it.

2. Be civil.

Disagreements happen, but that doesn’t provide the right to personally attack others. No racism/sexism/bigotry.

3. No bots, spam or self-promotion.

Only approved bots, which follow the guidelines for bots set by the instance, are allowed.

4. Shitposts and memes are allowed but...

Only until they prove to be a problem. They can and will be removed at moderator discretion.

5. No trolling.

This shouldn't need an explanation. If your post or comment is made just to get a rise with no real value, it will be removed. You do this too often, you will get a vacation to touch grass, away from this community for 1 or more days. Repeat offenses will result in a perma-ban.

Instance-wide rules always apply. https://legal.lemmy.world/tos/
