AT&T installed my fiber recently, and they don't even know how IPv6 works
I specifically asked AT&T to assure me that I would get a static IPv6 in addition to a static IPv4 address on my new AT&T Business Fiber. This is necessary so
that failover works properly at my DNS provider with IPv6 addresses. The installer tech didn't even know what I was talking about. The tier one tech I talked
to on the phone didn't know what I was talking about. I told him all I need is the IPv6 address and prefix length, and he couldn't even give me that. It then
occurred to me to just see whether my backup server has been assigned an IPv6 address and prefix length by the AT&T system, and it turns out that it has. As
expected, there is a /64 prefix length, but there is also a /128 prefix length. I can use the /64 as the public IPv6 address of my backup server, which I just
configured. Finally, IPv6 failover works properly! Thanks AT&T!

Good on you, man. I tried haranguing both of my ISPs about v6 ages ago and just ended up with nobody Of Clue. Then I
ended up using a Hurricane Electric tunnel haha.
Eventually someone somewhere must have gotten around to it. Sorta Just Works now, though latency even to the first v6 hop is noticeably worse than on
v4.
