I got a server with IPv6 only.

ping 2001:19f0:5:65e0:xxxx:xxxx:xxxx:xxxx:xxxx
ping: cannot resolve 2001:19f0:5:65e0:xxxx:xxxx:xxxx:xxxx: Unknown host
ssh root@xxxx:xxxx:x:xxxx:xxxx:xxxx:xxxx:xxxx
ssh: connect to host xxxx:xxxx:x:xxxx:xxxx:xxxx:xxxx:xxxx port 22: No route to host

The Ubuntu 21.04 server is up and running. I am able to login to the browser version of the console. It's the OS terminal that's not recognizing the IPv6 address.

I am on macOS Mojave

UPDATED:

ping6 ipv6.google.com
ping6: UDP connect: No route to host

So this is my ISP blocking ?
