I don’t have IPv6 at home— how can I test it out?
See answer below
ping6 2001:4860:4860::8888If this is successful, it means that your IPv6 is configured correctly. It will be able to communicate with other sites and servers that have IPv6 enabled throughout the internet. You can also connect to your server through an IPv6 tunnel. DigitalOcean is directly peered with Hurricane electric for best IPv6 over tunnel performance: https://tunnelbroker.net
