it already happened. also I sure as hell dont remember my ipv4 address

  Adoption has been flat under 50% for a year now.

    A bit less than 50% of the whole Internet. Wow. That's so amazingly unpopular. Why anyone bothers talking about something untold millions of people use every day is beyond me.

    It’s not flat: https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html You have to take into account seasonal trends. The summer is always higher, so yes, we’re currently below last summer, but we are above last April 1st, and this summer will be higher than last summer.
    - Gigachad 7mo ago
      Also just looking at the history it always seems to have flat periods with sudden boosts which never go back down.

      It looks flat to me since July of last year. Regardless, when you extrapolate that curve, when do you estimate hitting 100%?

        > It looks flat to me since July of last year. That was the entire point of my comment. You can’t compare fall winter and spring to last July. You have to compare last July to this July, which hasn’t happened yet, but when it does, it will be higher than last July. Today (April) is higher than last April. The reason for this is that more people are on mobile connections during the summer (kids home from school) so the summer (as well as the Christmas/new year week) are the highest points of the year. The fact that it’s “flat” since last July, the high season, means it’s actually still increasing. > Regardless, when you extrapolate that curve, when do you estimate hitting 100%? Never? But what’s your point? IPv6 is a failure if it only replaces IPv4 for 99% of traffic?

  I don't remember my ipv4 addresses either, but I recognize them as mine when I see them. I've never recognized an IPv6 address or prefix used in my networks.

    You can set your ULA to something like "fddd:192:168::/48" and then on your vlan you prefix hint, say, "66". Now, any device on that vlan will be addressable by "fddd:192:168:66::$host". For example, your gateway ('router') for that vlan would be "fddd:192:168:66::1". If you want to be really wonky you can script DHCPv6 to statically assign ULA IPv6 leases that match the IPv4, and expire them when the IPv4 lease expires, but like said upthread, addressing hosts via IPv6 is the wrong way to go about it. On your lan, you really want to be doing ".local" / ".lan" / ".home".

      > addressing hosts via IPv6 is the wrong way to go about it. On your lan, you really want to be doing ".local" / ".lan" / ".home". .local is fine as long as all the daemons work correctly, but AFAIK there's no way to have SLAAC and put hosts in "normal" internal DNS, so .lan/.home/.internal are probably out.

The "official" is home.arpa according to RFC 8375 [1]: Users and devices within a home network (hereafter referred to as "homenet") require devices and services to be identified by names that are unique within the boundaries of the homenet [RFC7368]. The naming mechanism needs to function without configuration from the user. While it may be possible for a name to be delegated by an ISP, homenets must also function in the absence of such a delegation. This document reserves the name 'home.arpa.' to serve as the default name for this purpose, with a scope limited to each individual homenet.

  I know your ipv4 address, 127.0.0.1. :) There’s something to be said for human readable addresses. I’m a little nostalgic of how the .hack world was envisioned, where servers had address names like Hidden Forbidden Holy Ground. If roughly 10 million words exist, then allowing any three words in order creates a space for 10^21 addresses… five words and you’re close to ipv6 address space, six words and there’s more combinations than ipv6 addresses.

I think the Matter standard is going to cause IPv6 adoption to increase significantly in the coming years. People will demand it, without even knowing what Matter or IPv6 are. They just want to be able to turn their lights off from their phone without any extra hardware or software.
- spaqin 7mo ago
  They've had years to demand it, I don't see why it would suddenly change. Most users who buy "smart" appliances are not power users, don't set everything up themselves and just rely on manufacturer's servers anyway and don't need a direct connection - and are okay with it.
- Gigachad 7mo ago
  Matter is only local networking. Essentially everyone has IPv6 on their local network. That said, I disagree with the parent statement that v6 isn't going to happen. It's already happening at a steady rate. From the Google stats it's steadily rolling out. Some countries are reaching 100% v6 deployment. I wouldn't be surprised if we eventually see some countries with high v6 deployments see services which are v6 only.

I’m always bemused when I read comments like this. Regardless of whether you think IPv6 is good or bad, it is happening. IPv6 traffic to Google goes up by a few percentage points a year, steadily, and is at around 50% now.
