# Start at some time between 2025-02-20T08:32Z and 2025-02-22T11:21Z, this VPS
# can't ping public network ipv6, e.g., `ping 2606:4700:4700::1111` will have
# no response. So default ipv6 DNS will not work, I have to force to use ipv4
# DNS here to make the VPS partially work. But still, can't ping outside ipv6
# issue is not fixed.

# the last address seems is the default?

# use the following will not need GatewayOnLink=yes in [Route] section, but I'm not sure if it is correct, I'm not sure if those ips could be accessed without gateway, more see https://superuser.com/q/1562380

# GatewayOnLink=yes needed for 2606:a8c0:3::1 gateway, maybe because 2606:a8c0:3::1 is not in the same subnet as 2606:a8c0:3:38d::a/64? see: https://serverfault.com/q/814419
