user name = zxcd, newly added DDNS = db.zx-invest.com, where zx-invest.com is registered elsewhere, entered correct IP address. But cannot ping nor ssh to it,
while ping/ssh IP address work.
Does that mean I need to do this delegate from the registered (Alibaba Cloud, in this case), but I only want to have 1 subdomain (db in this case) to
be delegated to zeonedit while keeping others (such as www) unchanged. Can I do that? If I delete zx-invest.com as my DNS from zoneedit, and create another new one that is not yet used, then I can avoid this delegation?
