Well, not ALL Windows machines…

“Systems are not affected if IPv6 is disabled on the target machine.”

I can’t remember the last time I saw an IPv6 machine…

It is on by default in Windows… More likely people have routers with it disabled.

Where I work, everything is on IPv6. Both the infrastructure for the software services that we run, and our own internal corporate network.

My ISP also provides publicly routable IPv6 prefixes over DHCP. Any layman in my city with this ISP will be on IPv6 by default.

I also use IPv6 for my LAN.

Like, it’s just kind of the default in my neck of the woods…

I have two different ISPs offering gigabit fiber to the home, neither offers IPv6 at all. One of thes years I’ll tunnel an IPv6 prefix or two onto my network to actually get some real world experience with…

That’s strange. Mine dual routes. So we get both. I don’t know they generally tell you the ipv6 unless you ask though as most internal networks are still using primarily ipv4

ISPs nowadays tend to be either having offered 6 for years or never offered it. Not much middle ground

My entire network runs IPv6. I don’t have any windows machines though.

IPv6 is enabled by default on windows. Additionally, MS does no testing against machines with ipv6 turned off. People that go through the effort of turning it off may run into problems.

It’s on by default with Win10 at least.

I disable it on all machines I build. And use GP to ensure it stays disabled.

There’s just no need for it on small networks. Just another thing running that can go wrong (as it did here).

It also contributes to increased troubleshooting when networking is acting funny, because now you have 2 stacks to consider.

My ISP enabled native IPv6 for me a few months back. It’s pretty great. I don’t have any windows machines, but I doubt my wife has disabled it on hers.

Anyway, our router is set up to drop incoming IPv6 traffic by default, sanely enough.
