acme.sh/dnsapi/dns_dynv6.sh
Felix Schmidt a2bc79ddd5 Fixed a bug where trying to add entries where the fulldomain contains upper case characters would not be accepted (dynv6 API rejects those).
Now the fulldomain will be cast to lowercase first which should not make
any difference since DNS is case insensitive.
