I feel your pain Atooyi
At this moment DCS does not offer Third Party Server support (Like you rent from a company like Gameserver). Some squadrons have there own servers, but they are not Hosted
Back in April 2017 Matt Responded:
For now, you will be required to purchase a separate map key to act as the host. At some point, we do plan for "server side only maps", but that will first require dedicated server support. While still in the cards, we currently have some higher priorities for those staff members.
Hopefully this will happen now that 2.5 is out.
