wget included in alpine / busybox does not support IPv6
I was trying to download something from github, which is IPv4 only. The network provides DNS entries AAAA for github (so called DNS64) and wget should try to retrieve files via IPv6. However the result is that wget only tries IPv4:
Connecting to github.com (220.127.116.11:443) wget: can't connect to remote host (18.104.22.168): Network unreachable
This breaks Alpine on IPv6 only systems with DNS64/NAT64, which tend to become more common.
I assume there is a busybox config / file for enabling IPv6 - if you can point me to the config, I can make a merge request with the required change.
