Something I want to experiment with is IPv6 DNS. IPv6 has enough address space that individual devices are universally uniquely addressable. With an AAAA record you can point DNS at an IPv6 address. So I want to try setting DNS to point to a specific device... though I haven't gotten around to it yet.

IPv6 DNS certainly works, as long as you're not using ISP provided home equipment that's too stupid to let you allow incoming connections on IPv6; but only if you always have IPv6 access where you want to access the things from.

IPv6 on public WiFi or corporate networks isn't a given, and where I live, neither is cell coverage, so I wouldn't want IPv6 only for important services.

I wanted to try this too, but my Comcast IPv6 prefix is unstable, and keeps changing.

It makes it difficult to even use IPv6 internally, because the LAN tracks the prefix, so addresses keep changing.

If you aren't already aware, you probably want to use Network Prefix Translation (NPT) with Comcast.

I've been told that, and my router is pfSense, which claims that it is possible, but the documentation says something along the lines of "You can use NPT!" and then doesn't explain HOW.

I haven't figured it out yet.
