IPv6 Login

It is the year 2021, and I logged into one of my servers using IPv6 address. So far I had struggled with using IPv6 address for anything useful. Today, I was able login to a server directly from my home using an IPv6 address.

vultr.com provides servers for USD 2.5 per month, with a restriction that it will only have IPv6 address. But if you can ssh to it, why not get those cheap boxes?

$ ssh -6 root@2001:19f0:5401:129f:5400:02ff:fea8:1fde
The authenticity of host '2001:19f0:5401:129f:5400:2ff:fea8:1fde (2001:19f0:5401:129f:5400:2ff:fea8:1fde)' can't be established.

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
