shows "connect: Network is unreachable". Am I using ping6 wrong?
We also need to confirm IPV6 works outside AT&T's network.
Edit: Just tried Google's DNS. 8.8.8.8 works, but their IPv6 doesn't, so I guess this was a bad test.
Edit2: Learned about nslookup, but it does not seem to work with either Google or CloudFlare's DNS.
nslookup reddit.com # Works
nslookup reddit.com 1.1.1.1 # Works
nslookup reddit.com 1.0.0.1 # Works
nslookup reddit.com 2606:4700:4700::1111 # Does not
nslookup reddit.com 8.8.8.8 # Works

Edit3: Apparently my ISP doesn't support IPv6 yet.
You're using the IPV6 address correctly, does https://test-ipv6.com report everything's dandy for you? If it does maybe they're blocking traffic or there's something else going on.
I'm using Bell in Ontario. It could be either my Router doesn't support it, the Apartment isn't wired up to support it (if that's required?), my ISP doesn't support it in my area, or my Bell internet plan doesn't cover IPv6...
I'll ask them about it when they ring me up next time asking for more money.
fwiw, I am an AT&T customer in Atlanta on their fiber service.
the nslookup reddit.com 1.1.1.1 does not return for me, if I connect to work via VPN it does. 1.0.0.1 and 8.8.8.8 do work without VPN. while the AT&T modem shows IPV6 I did not test.

You are definitely wrong. No daemons have to be running, ping operates using standard ICMP echo messages that are a part of any complete IP stack. Any meaningful OS will respond to pings unless prevented from receiving them by a firewall. It wouldn't surprise me to find that some embedded implementations skip that part for size reasons, but even in that category most devices I have available to me still respond. It's a basic network connectivity diagnostic tool.
What is unfortunately common though is people blocking ICMP at their firewall, either at the host level itself or further upstream. Sometimes they just block echo requests, but often they block ICMP entirely which breaks things in very weird ways from time to time.
Blocking ICMP in any way is generally to be considered harmful. It's not 1997 anymore, the "ping of death" is not a thing on any OS you should actually be connecting to the internet.

For me up in Canada, ping 1.1.1.1 works. But
