  Certificate transparency, unless you use wildcard certs

    It’d be better and more accurate say the list of certificates then.

    Sub domains aren’t public unless your DNS server has XFER on.

      Interesting! I’m going to look into this. Not sure my provider has this in their UI

  It trivial to get a list of all registered domains and subdomains and the IP addresses they map to. There are any number of paid services to make it easy (e.g. subdomainfinder.c99.nl) but I’m pretty sure there’s also a way to do it yourself.

    Except it isn’t. Saying is trivial is just gross generalization. It’s trivial to configure bind to have internal zones that aren’t resolvable publically. It all depends on configuration, such as reverse ns entries, zone accessibility, etc.

      Actually, wait. Something you a said might actually be just what I’m looking for: you mean that I can have DNS entry for mydomain.com and no additional AAA records, and have a cert for nextcloud.mydomain.com (or wildcard maybe?) and somehow still be able to use name based virtual servers?

      Hmmm. I thought I was going to be limited to path-based.

      Explain more?

        A solutrly. Simply use ACME with the DNS validation method. Using bind you’ll want to create keys and allow TXT access for those keys to the validation domains. That’s all you need the actual domain doesn’t need to be resolvable with an A/CNAME record. Internally you can run an entirely different DNS server to resolve your hosts, use hosts files, or use bind zones.

      Okay. Yup, that’s probably true. I’m not that deep into network stuff. But, if you’re just doing the basic, ‘ha.mydomain.com => 121.41.38.9’ that works out of the box with host based b-hosts, then yeah, you’ll get traffic on that within 24 hours.

      I reckon if a person understands what you’re talking about though, they’re already doing better than most.

    This is kind of why I have wild card on my main domain… Nothing on www.
