Just Fucking Use IPv6

While I mostly agree with the idea, I dislike the appeal to original intent that often comes along with insisting "well direct device to device addressing is the way the internet was originally designed."

And its like true, but also the internet wasn't built with the intent that my fridge, lightbulb, etc were all gonna be online either. Of course the solution is a sane firewall not NAT, but similarly all of that is beyond the original scope as well, such is life.

In any case, ipv6 is an easy qualifier of several for me to apply stronger anti-bot checking, without really impacting my intended audience. Of course geolocation, ASNs, alleged user agents, etc all weigh in too.

Oh no, the devices in my WAN aren't directly exposed to the internet! What ever will I do‽

There's lots of reasons to push for IPv6, but the ability to not have a NAT is not a good one. I absolutely want everything on my network to be behind at least one layer of NAT. When setting up a router, I have two choices of internet protocol versions:

    Choice A: If I set it up right, everything is behind a NAT.  If I set it up wrong, there is no connection to the internet.

    Choice B: If I set it up right, everything is behind a NAT.  If I set it up wrong, Everything gets directly exposed to the internet.

Someday I'll get around to learning how to properly set up an IPv6 LAN, but until then, I'll just use the default IPv4 setting.
