Resolving servers internally

I have a server that I want to resolve internally, say the internal IP of it is, and I want to resolve it to a domain.

Do I need the Enterprise plan for the DNS mapping and DNS forwarding?

Neither of those features will do that. The client DNS mapping resolves VPN users in the format, the DNS forwarding sends subdomain requests of that domain to another DNS server.

Any DNS provider can be used to register a domain to resolve internal IP addresses.

Oh ok, wasn’t sure what those features were for, but that does make sense to what they are actually called.

So I’ve set up a DNS server and changed the DNS option in the server in Pritunl, but none of the clients are using it from what I can tell.
