DNS should be auto configured and work with multiple redundancy these days. If it breaks, so much that you cannot do a dig, you need to re think your network.

Oh yes, that's really convenient for home users. "Install this thing on several computers and keep it in sync or you're not qualified to have a network"

really home users who mess with DNS settings? Lot of people here are living in a bubble.

Adding two extra bits to each octet, making each octet range from a still memorable 0-1023 rather than 0-255, would result in an addressing scheme 256x larger than all of IPv4 combined. The entire internet works fine even when IPv4 was nominally exhausted. NAT and CGNAT are not sins, they're not crimes, and there's no rational reason to be as disgusted with them as IPv6 fans are. Even then, IPv4 exhaustion wasn't rea…

I don't have your problems with ipv6, and I'm actively using it. I don't have to rely on extra commercial entities to be able to reach my network. I did have a problem with hosting my own shit because my ISP by default does cgnat. That cost me an hour of my life to convince a party to give what used to be normal, end to end connectivity.

The tailscale client and the headscale server are both open source, you don't need to rely on commercial entities.

Wouldn't easy and accessible self-hosting be a major privacy win if that's your primary concern? Sounds much more private to run a Minecraft and Mumble server on an old laptop in a friend group than paying a commercial entity like a hosting provider to know about it and have a back door.

Easy and accessible self hosting isn't the primary concern.

It's much more private and secure to run that Minecraft or Mumble server on an encrypted overlay network like via headscale + tailscale rather than exposing both services directly to the entire planet.

But again, the primary concern was only ever address space.

If you're remembering your IPv6 address you're doing IPv6 wrong. In fact, it's good practice to always use a temporary IPv6 address. https://datatracker.ietf.org/doc/html/rfc8981#name-problem-s...

Yet another reason why ipv6 will never happen

Go 128-bit or go ::1

Home users would ideally be served by things like mDNS and LLMNR, which should just work in the background. If I want to connect to the thermostat I should be able to just go to http://honeywell-thermostat and have it work. If I want to connect to the printer it should just be ipp://brother and I shouldn't even need to have a DNS server.

The only case where I care about an IPv6 address is for something I actually want to expose to the internet. A temporary address would be quite annoying in that case.

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 expi…

I run split-horizon DNS on mine. By far my preferred solution.

I don't even bother with split-horizon. My internal hosts are in public DNS under a subdomain.

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

It’s not flat: 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.

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

What would have been your solution to needing more bits? More information is always going to be harder to remember.

Adding two extra bits to each octet, making each octet range from a still memorable 0-1023 rather than 0-255, would result in an addressing scheme 256x larger than all of IPv4 combined.

I disagree wrt NAT. It creates huge problems for many p2p applications.

DNS, Avahi are super usefuler.

Good luck when you're trying to troubleshoot and DNS not working is one of the symptoms. 8.8.8.8 and 4.2.2.x are easy to remember.

OK, so use the IPv6 endpoints? Write them down if you have to use them that much?

- 2001:4860:4860::8888

- 2001:4860:4860::8844

If you hate typing that much, computers may not be for you.
