I'm interested to purchase a wild card SSL certificate for my public domain (say example.com), so that we can run intranet web servers using a universally recognized CA (e.g., GoDaddy). I do plan to publish the DNS names publicly (e.g. internal.example.com), but their IP addresses are actually LAN addresses (e.g., 192...*). We want to use public DNS, because these web servers may actually be development laptops which travel around, and thus we will use Dynamic DNS to update. It's our intention that these web servers will only be available on the LAN each one is currently running on.
Will that work universally with all clients, e.g., TLS v1.2 ?
Thanks.
