AWS IPv6 only DNS does not work
I launched a instance with alpine-3.17.0-aarch64-uefi-tiny-r0
with a IPv6 only subnet and the DNS did not work.
$ cat /etc/resolv.conf
search us-east-2.compute.internal
nameserver 172.31.0.2
The resolve conf has VPC IPv4 address, which does not work. Manually adding fd00:ec2::253
to the file solves the issue.
