What's keeping autodiscover.cathaybk.com.tw from an A

Give autodiscover.cathaybk.com.tw an IPv6 address
Ask your hosting provider for the site's IPv6 address (or the hostname to point at), then publish it as an AAAA record. If your host doesn't offer IPv6, a proxy that does can sit in front. How to add an AAAA record
Mail servers without IPv6
Your domain's mail goes to its own address, which has no AAAA record.
Nameservers without IPv6
pxdns08.cathaybk.com.tw, pxdns09.cathaybk.com.tw, pxdns10.cathaybk.com.tw, pxdns07.cathaybk.com.tw all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.

What this means
