Now that I think about it, DreamCompute is completely unrelated to the DreamHost nameservers. I create servers and then create the DNS records afterward, or not at all. I’m confident that we can create records for our DreamCompute instances on any nameserver, and thus get our LE wildcard certs.
I’m going to try this soon. As I said, I have my GoDaddy registrar pointing to the NS1/2/3 servers at DH, which then provides records for resolution to my DC instance IPs. I’m going to use the GoDaddy nameservers, create the CNAME, MX, TXTs, and other records there, and then apply a LE wildcard cert.
I didn’t think about this earlier because I just point from GoDaddy to DH DNS out of habit.
I don’t know if this will work for DH VPS, certainly not for shared hosting, where we must have the DH DNS resolving their internal IPs.
