So, what is the threat to a home IPv6 user who has WiFi and an Internet of Things with minimal/non-existent security? I personally feel safer behind a nice natted IPv4 firewall with ACL rules between my copper and WiFi subnets. I just feel that I have more control of the situation with a simpler network.
Ditto. I freaked the first time I saw my shiny new Win7 box routing internal traffic out past my FW, using IPv6 tunneling over a IPV4 web-proxy to open IPV6 networking through a MS-ipv6 forwarder back several years ago. Ever since then I've been sure to disable IPV6 services in Windows and build my linux kernels w/o IPV6. Increased networking speed by about 5-10% too.
That would be the theredo service. You can disable it.
Teredo https://en.wikipedia.org/wiki/Teredo_tunneling
Also, if you disable IPv6 on Windows, you also disable Home Group networking.
Running Windows 10 as a virtual machine under Linux with vmplayer, I like to run on it "gkrellm" to see a bit of what it is doing. Well, it displays two network devices: one is an intel something that is the expected network interface, but another is "Teredo tunnel", wich is IPv6 and is the one you mention above. It is also displayed in the output of "ipconfig", with an address of 2001:0:...something, and another fe80::... I believe it is used, for instance, for peer to peer sharing of updates, if enabled. - -- Cheers, Carlos E. R.
