Thanks for your update, though that wasn't necessary ;)
You can post IP addresses and the like inside code tags. eg. by surrounding these with `` (and/or using the <> button)
2A03:E600:100:0:0:0:0:79 or 2A03:E600:100::79

However, it works for me :(
I'm on Windows 10, which version are you using?
And are you sure you've got IPv6 on your device?
Can you ping this address? Win + R -> cmd -> ping 2A03:E600:100:0:0:0:0:79

I was trained with IPv4. I am using WinMTR64.exe from WinMTR-v100.zip on:
Edition Windows 10 Pro
Version 21H2
Installed on ‎8/‎16/‎2020
OS build 19044.2251
Experience Windows Feature Experience Pack 120.2212.4180.0

On my building's wireless network, ping gives me "PING: transmit failed. General failure." and "Packets: Sent = 4, Received = 0, Lost = 4 (100% loss)," but calls that host "tor-exit-anonymizer-v6.appliedprivacy.net". tracert gives me "Transmit error: code 1231." ipconfig gives me "Link-local IPv6 Address . . . . . : fe80::8e5b:8af4:7606:25a6%17", along with my normal IPv4 Address, Subnet Mask, and Default Gateway. Everything works if I switch to my mobile network (I guess that supports IPv6, as I get an "IPv6 Address"). Better error messages would help.

well.. it's hard to give any better error message if any of IPv4 or IPv6 don't work or don't even exist... especially when windows only returns "General failure".
However, maybe it wouldn't be wrong to add "please make sure IPv6 is enabled and working" to the message.
