Website url

I’m hosting my wordpress website on my own VPS. The url is IP of my VPS, and then I bought domain on godaddy. I forwarded my bought domain to my website url which is IP of my VPS. Now when I type domain I bought on godaddy it goes to my website but you can see VPS IP and I don’t want that.
Ex. I bought http://www.example.com and when someone type http://www.example.com it goes to 111.11.111.11. I want http://www.example.com to stay and not change, so if they go to http://www.example.com it stays http://www.example.com. Is there any way to do so ?

Thanks
