subdomain

Our company owns a domain say www.mycompany.com. I understand that it is trivial to get an SSL certificate for above domain since we do have a website running on that address. We want a certificate for a subdomain say sub.mycompany.com. We intend to use this sub-domain in our organisation network only and have no plans to publish a public website on this subdomain.

So the question is "Is it necessary to have a DNS entry for subdomain, resolving to our IP address and host some page on that address?" I hope proving that main domain is in our control, we can get an SSL certificate for sub domain also. Is it possible?
