To have an web address in "mywebsite.com" you need to purchase or have a web domain name.
We do not provide this kind of service.
Once you have purchased the web domain name, you need to make the redirection in the configuration of the domain name, and configure the redirection to 168.xx.xx (the IP of your server).
For example, tsplus.net has a dns associated to the public IP 18.104.22.168.
You can check that example this way: run CMD, and type "ping tsplus.net".
You will get: Pinging tsplus.net [22.214.171.124] with 32 bytes of data:
