Are there any advantages to IPv6 other than more addresses ?

In theory, IPv6 could be slighty faster over IPv4. https://superuser.com/questions/1055584/how-does-ipv6-affect... - Smaller headers - Simpler routing

And no CGNAT which should make a bigger difference. Xbox live supported IPv6 for years because gamers really care about latency.

>IPv4 servers are reachable by IPv6-only clients How does this work?

I forget this part of IPv6 class (I've literally gone to several IPv6 classes throughout the years but then end up forgetting details because I've yet to use it in production), but since the IPv6 space is so large, it's trivial to put an IPv4 address into it, and so they make NAT 6to4 type gateways that map the IPv4 internet into a block on the IPv6 network.

I'm curious how much of this is mobile vs desktop. My assumption is that a much larger percentage of the traffic on mobile is ipv6.

In Germany, where the Google statistics show 64% IPv6 adoption, mobile carriers were actually the last to support IPv6, but even the last mobile carrier enabled it around a year ago. Now it's mostly businesses that are still not using IPv6.

I believe in the US ipv6 mobile adoption was much quicker.

I realize there are a million ways to leak addresses, but in theory is a private ipv6 space brute forceable? ie: I have every service listen on a port on some IP, they all discover each other through some specific channel (like dns). Assuming the attacker doesn't have access to that channel, they would have to start scanning every ip to try to discover services, yeah?

There's neighbor discovery.

Get a raspberry pi, set up two vlans, run wireguard, and send 100% of your uplink traffic to a remote vpn endpoint. This gets you off their IP, and also has the added benefit of not letting them analyze your traffic.

Oddly the hardest part of this right now is getting your hands on a raspberry pi!

You can get wireguard running on any consumer network appliance capable of running OpenWRT.

Northern countries have lower adoption, I wonder if IPv6 works better in warm climates.

Just a small anecdote (I’m usually based in Asia); Recently I’ve been building a network analysis tool (like mtr) and I wanted to test it on macOS with IPv6 and struggled to find _anywhere_ where I could (i.e. home broadband, office, Internet cafes, mobile hotspot etc).

Of course, spinning up a cloud VM is an easy solution these days, but I was surprised at how poor the IPv6 adoption was where I live.

I’m on Vodafone/Kabel Deutschland. IPv4 only, my only option would be to switch to CGNAT to get IPv6, which I’d rather not.

My website has a few hundred thousand users. My development is completely user driven. I get hundreds of feature requests and other emails regarding my site per month. So far, not a single user mentioned IPv6. So I never added an AAAA record. The codebase has grown for over 10 years now. God knows what subtle breakages would happen when IPv6 requests come in. I wonder if I ever will add IPv6 or just leave the site ru…

I think most or even all http servers and operating systems already can handle IPv6 no problem, one can set server bindings just the same as for IPv4.

Hetzner and other providers of this size already support hosting options for IPv6.

That said - my home ISP is not providing IPv6 at all, ISP we were getting office connection also provided no IPv6.
