More information would be helpful. I am not sure what you are trying to do, nor what issue you are having.
You can set an A Record for your server IP as your domain at the DNS level. I would suggest using CloudFlare to handle DNS as their resolvers are a bit faster than others, and it’s a much more simple task with CF.
