IPv6 address detection fallback not working correctly #95

Open apschultz opened 2 years ago

apschultz commented 2 years ago

The +short method of dig may return outputs in the case of an error. For example, if no IPv6 DNS server is available:

/ # dig +short @2606:4700:4700::1111 -6 ch txt whoami.cloudflare
;; connection timed out; no servers could be reached

It would be better to check the exit code and that the contents conforms to an IPv6 address string.

It appears this is the same as https://github.com/oznu/docker-cloudflare-ddns/issues/92 just for IPv6
